Thank you for your support! - Розваги
what a legend! germany just legalized a specific plant for recreational use including home-growing them, so i got into indoor-gardening :D your explanation of the ventilation system helped me so much! also: listening to your calm way of speech is rly wholesome, i wish you were my pops.
Lucky Germans. I’m in prohibition land. Can’t wait for legalization of its coming to my state.
@@Danieltoshsplumber good luck it wasnt easy i tell you :D
Dude Bob Ross of growing tomato plants
Ps....how do I use the duct temp. Control???
Scott, excellent in formation . One point you may not be aware of but one that is important to me. I am hard of hearing. It's not a volume issue, but a clarity issue. Very common on those with a hearing deficiency. Your speech pattern is superb, separating your words for comprehension. Thank you for that. I have no problem understanding every word you say. The information you give is first rate and easy to un derstand. You break down everything extremely well. Thyanksagain.
Simplest, most detailed explanation of the use of an inline fan with carbon filter. Thank you, kind gardener!
THANK YOU FOR THE EXPLANATION! There is not a lot of videos explaining why or when to use the exhaust system and I appreciate the thorough explanation of why we exhaust!
As a commercial HVAC expert, either one of the fan/filter configurations you explained would work depending on the users mounting requirements. However, you want the exhaust air leaving the tent to be drawn from the top of the tent to remove any stratified air (stagnate air pockets of heat or humidity). You want to utilize the mesh screen(s) at the bottom of the tent for makeup air or fresh air going into the tent. This creates a complete airflow pattern from top to bottom (Chimney effect). Putting both exhaust and makeup air at the same level will cause uneven airflow because the fan will "short cycle". Meaning, the incoming makeup air will not circulate through the space first before being exhausted.
Also, use the cords and the cord locks that are provided for each hole to secure the flex duct. Not only does this support the flex but it also closes the hole around the flex duct creating a tighter seal. When installing the flex duct make sure you do not leave any excess that you do not need. You want it as tight as possible with a few bends as flex duct really creates a lot of static pressure losses which results in loss of airflow. It would be the same principle as installing a dryer vent. Tight and straight but not so tight that it tears or pulls off the flex duct.
I wouldn't get too caught up in air changes per hour calculations. Like you rightly pointed out, the manufacturers have sized the fans included with the kits to provide more than enough air changes. The user just needs to make sure the fan installation allows the fan to function proficiently by the proper install and setup.
Good info. Thanks!
How do you get fresh air into the tent passively without a inline fan?
@@sean1325 Chimney Effect - The heat from the lights will rise. Open the TOP hole for heat to go out and open the bottom screens to allow fresh air in. As the hot air rises it will pull colder air from the bottom.
However, I don't think this will be sufficient to keep your tent temperature below 80°F. From my experience running temps above 82°F can cause plant stress. The leaves turn brown, the flowers drop, and the fruiting slows/stalls. With the amount of BTU's being produced by the lights you're going to need a fan.
Thank goodness I read you both info. I was looking to hear that and I found it here😘😘😘
I use a 6" inline duct fan going into, as well as a seperate one, to exit my tent. I also use a I use a charcoal filter mounted inside of my tent, for the exhaust, which is then ducted to a window fitting - to expell the air outside. Then my entry is pulled from the same window fitting, as to pull cold, winter air over my LED lights. It's amazing, when blowing 40°F straight into the top of my tent, creates a perfect 77°F environment for my plants. These leds can get HOT!
Perfect timing, thank you! I was looking into a vent fan for my orchids. I moved them all into one area, to protect them from damage from guests and children. I was concerned about heat buildup and lack of air flow in their little space.
Makes very good sense. And more reason to operate a little fan for my seedlings in months ahead.
Thanks for helping us
Thanks much! Absolutely amazing the effects of different levels of air circulation I've seen on indoor pepper plants. Cheers!
You say “ vegetables” I hear “festival!” ❤
This is Fab, and Thanks for having No back ground music, Cheers to ya..
So again another valuable video. Let me explain. My winter indoor greens seem to be very slow. Then as soon as you mentioned the importance of a fan I paused your video and ran to my seed stations and installed a fan. LOL. Thank You Again!
I immediately wondered: what plants emit such a strong aroma that they would need to be filtered? As always, thanks for a fine video. I have learned such a lot from you that I feel personally in your debt.
Hint! Hint! It’s legal in the state @gardenscott live in lol!
@@nkc9788cannabis
Weed, but even if legal in your state, the odor of cannabis is offensive to people, can make some sick, and believe or not, some have allergies. When your next door neighbor is a zero lot line, or townhomes, apartments. I personally can’t deal with it and it makes me very sick like throw up sick. And you bet, I’d be calling the authorities.
But as he explained well - there are growing reasons for ventilation.
Weeds legal in alot of states here in VA every citizen can grow their own
Tomatoes, sage, spearmint to name a few that reek and require filtration every minute they are lit up indoors.
Really interesting stuff and very appropriately timed. Love seeing your seed sowing set up.
Thank You for this video. I always wondered about the grow tents and how to get air in it. I hope to use some of this info in my greenhouse in my garage that I start my vegetable and flower seeds in.
Thank you very much for such a detailed product introduction!
Thank you, Gardener Scott!!
Very useful information, thanks for covering this topic. First time grow tent user, starting tomatoes and flowers
Most tents have a top vent. Cut a plywood board (or similar) the same size as your tent, then cut a hole in the board the same diameter as your fan intake. (Make sure you match the position of the hole to the position of the vent.)
Place the board on top of the tent, resting on the frame, then put the fan intake into the hole in the board. Add a filter on top of that if you need one. The whole contraption looks like a chimney.
Pro - No ducting is needed. No hot and stagnant air at the top of the tent. No space is lost inside the tent. Airflow through the entire tent (if the intake is at the bottom). It takes up no space outside the tent except above the tent, which often isn’t used anyway.
Con - The fan might need additional L-bracket support to stay in place, especially if the hole in the board is too big. It might be too tall, depending on the tent and the room. Vibrations resulting in noise might be transferred from the board to the frame (put something “bouncy” between the board and the frame).
One of the best and most informative segments I've seen on the topic of venting a grow tent.
Thanx
Very detailed and exactly what I needed to hear. Thank you for your time, good sir 🙏
Very cool setup
If you want to get fancy, they have temp/humidity sensor controls that will turn on your ventilation automatically when a pre set limit is reached.
The only problem I've seen with the automatic fan control is that it only controls to a temperature set point.
@@timdavis6088 look into ac infinity. They have really nice setups, and almost everything can be controlled via bluetooth.
Edit: They can be set to humidity, temp, or timed.
@@timdavis6088 😊😊
What a great and concise video! Full of great information!
Great information, thanks for sharing your experience
This was really interesting, thanks for the great explanation!
Wow, the new sf stuff is looking nice. My SF-2000 has been amazing for the past 2 years.
Thanks for your love and support~
@@SpiderFarmerjust order a full grow tent kit 🙏🏽💯
Cheers, which you a happy grow journey@@blockg2256
Another great video. That carbon filter is needed to keep the smell of those terpenes in check! 😁
Bro attached his carbon filter when the video was done. 😊
Great video! Very informative and funny wink and a nod to the aromatic plants
Great video thank you so much. Very informational.
I throw my fan on the top of the tent, about 12 inches of duct through the top of the tent will daw the heat out of the tent and pull cool air through the bottom. That's how I do it gives you max room in the tent.
11:47 Can’t wait for that video 😁
I'm beginning to work in that direction. 😉
@@GardenerScott Iv been watching you for over the past 5 years or so. Mainly along gardening, fruit and veg, organic growing lines etc. I'm actually currently looking for various equipment and the Spider Farmer caught my eye. Got space for a 150x150x200 and was thinking about getting the SE7000 730W to pair with it. Do you think the 6" extractor would be able to pull that sort of air space without having to be on full? Also would love to see Gardener Scott branch into other passions, interests, avenues etc ;)
@@theseeker4911 You might want to contact the company for more info, but it should work. I am looking into branching out. ;)
Great info, thanks
The Carbon Filter does actually lower the humidity of the waste air exiting the tent a little too.
Great video!
Love your channel ☀️😃👑💯
Doesnt have to be smell, could be spores aswell if you growing mushrooms in there :P
Awesome video
Nice video~
Understand that for good results you should be dumping the used air outside of the room the tent is in. If you do not do that then you will be recirculating some of your used air. That will of course lead to slower growth and lower yields.
“Particular aroma” ;)
Scott, I'm just getting interested in tents to extend my growing year. The explanation of the 4 options for installing the fan/filter is INVALUABLE and worth the price of admission!!!
I foresee growing some tall stuff and would want both those bulky items out of the tent; suggestions on how to safely & securely accomplish that?
Thanks for making life easier for your fellow gardeners!
Depending on what you grow you may not need the ventilation. My tomatoes and peppers are doing fine without the machinery and with the door continuously open. If you need it, installing on the outside and plugging the airflow through a tent vent is probably best.
get a co2 system and mini air conditioner - double your yields without any need for ventilation
great video thank you. im going to setup my fan on the outside just like you up until now i just used honeywell house fans one on bottom sucking air in the vent and one sittin on top sucking air out top vent, im sure it will help keep my light cool and prolong the life of it
You are supposed to run the extraction system 24hrs a day. Outdoor plants do not stop getting air exchange at night do they?
So you should do the same thing or you are putting stress on the plants.
Can’t wait for your cannabis growing video!
Fan-tastic
I bet Gardener Scott can grow some killer weed 😂
😉
Everything Gardener Scott grows is exceptional!!!
Nice video!🙏🏽😃👑 I’m watch later today. Peace and Blessings to you
Awesome thanks for the video, i wondered if you used grow tents. Can we get a video for LED lighting and watts per area coverage
Thanks. That video will be coming in the months ahead.
I just use your discount code on a 2x2 full grow kit. Save my self $31 Thankyou! Hope it everything is legit and I get my package soon can’t wait 🙏🏽💯☀️🍇🔥👑
if this interests you watched weed growing channels they have growing down just do what the say but grow tomatoes flower cycle and fruiting stage need to be varied. It is likely the most researched indoor grown thing in the world.
I didn't get those climbing hooks wit my kit...
🍃 ❤🙏🏽 good vibes ⚡️
who else has those aromas?
I have a fan like yours but no controller. It was given to me but without the controller. Can I get a replacement? I’m so new to this and love your videos
You can contact the company and ask.
One thing I forgot to mention was to make sure your exhaust and makeup air are not on the same side of the tent. The exhaust needs to be exiting one side of the tent and the makeup air needs to come from the other side. If you have them both on the same side it will also cause the fan to short cycle. Meaning, your hot humid exhaust air will be pulled right back inside from the makeup air vent at the bottom.
Think of a bathtub full of water. If you ever played in the tub as a kid by paddling the water in one direction on one side of the tub, what would happen to the water on the other side? It would start moving in the opposite direction as the side you were paddling on. This creates a circulation in the water that you can see. Well, the fan creates the same effect only you can't see it. Only in this case you do not want it to recirculate the same air over and over. You want it to mix with the room air so you can better manage the temperature, humidity, CO2, and O2.
Thanks for the great expert suggestions.
I have the fan at the inside with a Carbon filter and a second Carbon filter at the outside where the air comes out, just started growing those smelly plants will this work out?
It should work if the fan is strong enough. Two filters puts extra stress on the fan and reduces airflow.
Hi. Great material. I have 1 question. Must be the growbox completly closed(only air going outside? Or some hole under must be opened to make a fresch air intake? Sorry for my bad English...
It does not need to be completely closed. Most of the time I had the door open for fresh air.
@@GardenerScott thanks for your answer. 👌👍❤️
I notice some people also use small clip-on fans. Is this necessary when you have one of these in-line fans?
The clip on fans are often used to strengthen the plant with direct air. The in-line fan doesn't have the same affect.
The submit button on your web page doesn't seem to work
I just got an AC Infinity setup and have it all installed now. The tent is trying to collapse when the fan is running. I have not seen any videos that suggest leaving flaps open for ventilation. I thought keeping the flaps closed is best to reflect lighting. How are you handling this situation?
I've been leaving the flap open. I have my tent next to my other lights so I'm not as concerned about reflective light and the extra air seems to help.
Can your fan be placed in the attic to save tent space or is that too hot for it?
If you have an attic and enough tubing it could work
Did I miss it? Or how are you getting the intake? If we have the exhaust set up, do we need another fan for the intake?
I leave the tent vent holes open and the air draws in there.
@@GardenerScott oh ok, thank-you.👍
I’m wanting to get a nice grow tent for my basement! I have a house with a full upstairs and basement two bedrooms living room and a huge bathroom! But my brother said that I had to run the exhaust pipe out of some windows? Is this true? Any help would be greatly appreciated thanks.
As I mention in the video, a charcoal filter can help avoid venting outside.
Hi, great video! Got one question, for a growing container similar to yours (a cabinet), do I need to have a small hole somewhere on the bottom so that air can get in? Does it need to be partially covered? Thanks.
Yes, there should be ventilation holes. Mine has a number of them already built in on the sides. They can be covered to hold in humidity but it's not always necessary.
@@GardenerScott Thank you very much!
@@GardenerScott Also if the whole system is set up on the inside, the smell won't be cleaned by the carbon Filter? Does it need to be on the outside and the fan blowing into it?
The filter can be installed to fit on the inside and vent filtered air to the outside.
@@GardenerScott Thank you for your fast replies
i got a question about air supply inside the tent do u use extra ventilator to supply fresh air while the other one filter the inside air ?
The single fan is enough for ventilation.
@@GardenerScott what if the room air isnt very fresh all the time ?
Is it just me or does that sound about double of the 32 decibels they claimed?
If you have a humidifier ensure it has a filter or it Will kill your carbon filter. Buy the tallest tent you can fit, this helps with plant management and temp control
Besides gardening, I'm also into home brewing. I wonder if all the carbon dioxide given off by the yeast as they break down sugars into alcohol would benefit my plants. 🤔
It sounds like it could work.
I can't believe I have never tried or thought of that before! I like your thinking. Have you tested that out yet? Would need a CO2 measuring device
What happens when we go off the grid?
Are these rendered useless? Or is there another way to give the plants their nutrition?
The grow tent doesn't need electricity but the fan does. Making your own compost, worm castings, and organic fertilizes are easy to do.
I read it’s bad to push air out the filter ?!
Is there a way to email you some cover crop questions I have?
You can leave a question on my cover crop videos, like this one: ua-cam.com/video/zsgmn4WkDiw/v-deo.html
Gardener Scott: Were you completely satisfied with this grow tent kit you purchased from Spider Farmer? Would you buy another system exactly like this one, should you require another? Were you happy with the total cost you spent on this entire system? Do you think there is a better system out there for approximately the cost of the Spider Farmer system?
I won't say I'm completely satisfied. The small size is the limitation I'm dealing with now. It is very well made and will last for years so I look at it as amortized cost over a long period. I'm waiting on final judgment until I reach the point of indoor harvest.
But Scott, if you ventilate the grow tent, wont you be purging
the etylene gas tomato plants offgas to ripen the fruits?
!
Much of the ethylene gas remains near the fruit and it's enough to ripen it.
11:53 lol
👍🌱🇬🇧
nice thank you i have the same size tent and same size fan
My tomatoes stink! Definitely need that carbon filter
Does this device act as an extractor and offender simultaneously?
It can filter air using the carbon attachment.
I would not purchase any spider farmer productsGreetings from Spider Farmer.
Sorry, our tent does not have a warranty, so we cannot accept your request.
You can seal it with tape on top and open the window from below.
If you have any further questions in the future, please feel free to contact us any time and we will be happy to assist you.
Have a nice day!
Best Regards
Viewing window velcro falling apart within 30 days they do not stand behind their products
Yeah. That’s why it’s priced for a single use! We all make that mistake our first time. Spider or vivosun. Then we upgrade!
To tell you the truth, even with your explanations, the assembling of this ventilation system in the best/correct way, looks complicated to me. And the amount of clarity provided by the manufacturer's instruction? Oh Boy!
Lol just put fan it in the tent/room. Then Vent outside.. 😅
