- Join me as I conduct a comprehensive test of a DIY venturi in my DWC hydroponic lettuce system, using the precise Milwaukee MW600 dissolved oxygen meter. Watch as I explore the efficiency and effectiveness of this setup, providing valuable insights for fellow hydroponic enthusiasts. Discover firsthand the impact of venturi oxygenation systems on nutrient solution oxygenation in recirculating hydroponic setups. Gain practical knowledge and real-world results from this in-depth experiment.

• Stop using airstones!!...
More videos please! Good stuff.
Thanks! Will do!
Love your videos, im learning alot from your content. Thanks alot and please keep posting more.
Thanks! Let me know if there is anything specific you want to see!
@@SaludaGradeFarm things like how to do a price break down to know how much it costs to make one or 18 heads of lettuce? Can you show more how you prep your greens before selling in bulk or retail. Also whats the shelf life and some ideas for packaging. How many men does it take to run the show ? How many hours it takes a week? Also do u sell by weight? Whats the weight of lettuce in the nft and dwc what u think is better or use both a nursery and an nft.
Thanks from Australia appreciate the vids
Glad you like them!
Wow. Thanks!
You're welcome!
Hi Dave, many thanks for your advice❤ I forgot to ask your experience against algae what to use . Greetings
Hey! So I use a product called “garden friendly fungicide” sold by southern ag. It’s a concentrated BA bacteria that destroys algae and protects the roots from root rot! It’s not instant, takes about a week for it to fully dissolve the algae. Hope this helps!
Is the venturi runs 24/7?..
Is the Venturi less noisy than air pumps?
It depends on how big of an air pump you would need. I did find that putting a valve on the air intake can reduce the noise without sacrificing air flow. The benefit is added circulation and 1 Venturi can aerate thousands of gallons, and is quite simple!
Hi, this is Gisela from Germany.
Please tell me whats the name of the fertelizer in each tank.And whats your advice to use for to reduce PH. Thank you!
2 tsp per 5 gallons of 4-18-38 water soluble fertilizer, 2 tsp of calcium nitrate, and 1 tsp of epsom salt. Good luck!
Where are you located in what country?
US
how many aerator did you use in 1 system?..
I have one aerator which turns all the water about once every hour for fall-spring, and I double it in the summer when it’s hot.
are you using masterblend nutrients in your DWC? if so what formula??
4-18-38 plus calcium nitrate and magnesium sulfate. The 4-18-38 is similar to masterblend, but made locally at a ag supply store. It’s much less expensive, but basically the same stuff!
@@SaludaGradeFarm wow! thanks! you're right that's basically same. may i know your mixing ratio? like how many grams of npk(4-18-38), CalNit, MagSul per liter or gallons of water?
How many gallons per water pump are you using in that particular floating raft bed?
Right now 4500 gpm, if the temp shoot’s up past 75 degrees I will double it. So shoot to push the water through once every 2 hours in cool conditions, 1 time per hour in hot conditions.
@@SaludaGradeFarm Is that a typo (4500 gp'M'); vs 4500 gp'H'???
If it's not in error, then how many HP is your pump? Good video, thanks.
