In the US, I use the "Big Mama" rockwool cube, which is 8x8x8. It cost under $6 each at my local hydroponics store, which I can cut into 512 one-inch cubes. So the cost is about a penny each. I can cut it even smaller depending on the seed size, making it even cheaper. You use the same on the previous video and a clip in this video.
@@makeevenbetterlifechoices have you checked Growtopia Hydroponics in Buford? They have the Grodan slabs, 8x3x36 for 15.95. You could cut that into 864 1 inch cubes and be about $0.02 each.
@@pistolschlapper I actually cut into about one inch (25mm) size and use it to start seeds. Saves tons of $$, about 20x less. I think the Big Mama is the biggest out there.
In the states, I literally used to get paid to pick these up at the 'tomato grow shop' for growers, ha. We pay in the states (grodan brand usually) its 8 to 12 dollars for a 45 pack of 1.5 in blocks, with the paper wrapping of course, which most people dont even like. Thanks for this tip, bud!
Another great video! I've been doing a very similar process but within net pots using a smaller amount of Rockwool suspended in clay pebbles, works very successfully and has a little more reusability of resources. I've recently designed a 3D printed seed "pelletizer" which allows me to create a perlite/coco mix to suspend/sandwich the seed instead of Rockwool and it's working great so far - germination in 2 (cold) days and 100% germination. I originally tried 100% coco/peat but found, like you, the germination rate was poor - definitely linked to oxygenation or oversaturation of water. Happy to share some information if you'd like.
First time watching your show, great info. As a first-time Rockwool user, I bought my first set of cubes from Amazon, what a mistake, I opened the bag and had my scissors ready to cut and separate, but the first few fell apart, literally crumpled in my hand. Out of a set of 28 cubes, I probably got 6 good ones! So I'm ordering from the link you placed at the bottom.
I had found a really pretty good deal for Rockwool cubes at temu for about 7 or 8 bucks and the amount of them that I had gotten was quite a lot! If I remember correctly it was 100 cubes of Rockwool for 7 or 8 bucks definitely a steal if you ask me!! And I only have about 3 cubes left right now after taking care of my spinach and tomatoe seeds!! I'll probably wait until next year to get more though because I'm finally all done with planting my seeds in the cubes for this growing year!
Once again Hoocho! Informative, innovative , educational and so much more. Hands down the best channel for hydroponics in AU and possibly mother Earth. Not only do you give us product reviews and sources, methods and insight, you also convey in an honest, enlightening, conclusive way, with simplicity. Well done Sir!
Great video, but a mask would be beneficial when cutting dry rockwool. Those tiny fibers can easily get airborne and make their way into your respiratory system.
I love your 'No.8 Wire' style of thinking my Aussie cousin. As long as there is minimal to no compression/compaction of the 'rock wool' when cutting them, there should be no problem with this method. I agree, you are negating the whole purpose of having individual 'rock wool' blocks by having them packed together so close to each other in the grow containers.
I love the old peat pellet hoocho. But I dont use humidity domes with them. That made a HUGE diff. Or run the dome with the vents wide open from day 3 or 4 onwards.
In the states, and youtube, one of the top shops online is GrowersHouse (Arizona). Or MonsterGardens(california). Right now case of slabs looks to be 75, and you can get a discount coupon if you signup for newsletter on the growershouse website, with popup blockers and all that turned off. Thanks again man, I cant believe we never thought of this.
Great information on hydroponics. I want to start, but still concerned on United States suppliers. I have worked in college to make extra money years ago (over 40 years ago). I am determined to get myself into hydroponics in my retirement years. Thanks for the super presentations too!
Cut with size of 25mm³ ..we use 25mm x 25mm x25mm in our hydroponic farm , can save you alot of money. Cultilene Slab can cut into 720 cube and work well .
Here in Southern USA I find that a grass that grows along bayou waterbanks and also on ditches and waterways are a great sub for this. It forms a tangle of very dense roots. However, they are very hard to cut so I have to use shears. A slab cardboard or paper cutter (With gullotine blade) would be just right to cut dead roots into slabs...
I am a newbie but as a contractor , they use the cheapest form possible to get a result and for the US concern they will use all types of chemicals to achieve that result without a concern for health issues
Tried germinating some in wet paper, nada. Switched to 50/50 perlite / vermiculite and boom lettuce seeds were sprouting in 2 days. Have yet to try rock wool!
Great video dude, this’ll be awesome for getting a bigger garden started. Orrrr if you’re me and kill plants a lot, then it should make my failures a lot cheaper :pppp
So 2 questions 1is " hydroponic Rockwood same as the one used for construction? 2will it be mold resistant? Peat plugs suck and all of the one I did got white mold on it. Thanks
whats the difference between this rockwool and sound proof high density Earthwool insulation bats at $12/m2? they look similar especially when its being cut.
I'm lucky and have a commercial supplier an hour away. I can get rockwool ready to use for 4 cents each (I'm in US). This is definitely a good idea to save up.
So I bought a few of these bags today and it got me thinking wow $5 each that's cheaper than the Coco perlite mix...... But then again that's why the industry uses them.... I know your a busy guy and all but can I request, yet another grow.... Using these bags? Paying attention to the cycle times. Cheers mate keep up the awesome work.
@@Hoocho yeah I went to by one bag for doing the cubes. Then using them in my stormwater NFT. (Using red bull cans for net cups 🤪.) But at $5 each I bought 5 of them. You know because I was there and they were there and now here we are... ,,😆
Thank you for this very interesting video as always. Just a small remark, I think you like dogs a lot, because in Vietnamese the pronunciation "Hoocho" means "love dogs" ;-)
That really looks like it would be kinda hard to deal with cutting your own cubes! Thankfully the ones at temu were already cut into cubes and they all already had little holes in them I just had to separate the cubes from each other and get them all wet and then put the seeds into the little holes! Other then that that's a lot of work that you are doing with that Rockwool!!
I would love to know what kind of pumps you use. I have been using EcoPlus and was not happy with the 350gpm pump. After one year the flow has been cut in half and you cannot buy a new impeller. I am looking at using a sauna circulating pump and have one on order. It is 2 or 3 times as expensive but have a sauna and have never had to replace it. Immersion pumps seem to last only 2 - 3 years. I am working on 3D printing an impeller for my Ecoplus 350 with rare earth magnets and seeing if that improved the life of them. Also will replace the flimsy plastic shaft with a stainless steel shaft.
You can't really reuse it if the plant ends up growing into it. If a seedling dies in it, you can reuse it. It's not organic, and won't break down. It's a manmade product from inorganic natural materials, not something found in nature.
I live in USA... rockwool locally is dirt cheap in NYC lol. You must be needing rockwool cubes by the dozens of thousands. Also, if I were you, it would be wise to check the MSDS datasheet for the "construction grade" rockwool, the factory that produces them probably did not meet health and safety requirements that is safe for cultivation of plants that will be consumed/inhaled/smoked or ingested. They might spray some crap into those construction grade rockwool from degrading over time which is not good for planting or what not, you would be surprised what you'll find in the MSDS datasheet.
Hey buddy, please do more 3d printing vids , just waiting for my ender Neo to arrive ! Found a farm selling off nft channels at cheap prices . So scaling up from one chop N FLIP NFT ! PATREON supporter as you have cost me so much money so far I thought I had better send some your way lol😁
Curious to know what you do with the coco perlite mix post harvest. Is it a spent consumable or can you reuse it? Does it need to be sanitized in some way? Or maybe just composted and end life in the soil patch, creating a throughput consumable...
I'm in the states and putting together an aquaponics system. I appreciate this info and the info by others in the comment section! I would recommend for ease and less fly around, to either use a knife that will cut all of the way through instead of having to go in at both sides, or to cut off from the end and then cut that in half, to look like 2 sticks of butter then cut the squares. It would be a little more work but fibers would stay more intact.

Hey hooch, thanks for the videos mate, I have the spider farmer G12 - little hydro set up for the kitchen - herbs etc, but they give these grow sponges, that i dont think are ideal - the holes are 28mm then a net piece, so im dealig with under 20mm and its round, do you think I could get a block like this and make 20mm dia rounds? what would you suggest is better? stick with the grow sponges (approx 30$ aud for 50 at a deal) of start experiementing with rounds of rockwwool - also I kow you can get loose rockwool, have you played with that, the small circile shape is my problem, thanks mate
Get wet before cutting rock wool . This is the same as Asbestos fiber. Use a N100 Mask. Drodan blocks need to be drained fully 4 times in 24 hours. On a 4" or 5" block, I drive 25 small holes from bottom To top , stopping at 2/3 the way up with 26 small nails mounted on a 5X5 wood board. 1/2 ' thick. Poke holes when block is wet.
Root riot offer a tray form for £12-£14 pounds sterling uk, not sure if thats a good price considering a slab is only £2.50 but must be brought in bulk min of 5, I don't really see the point unless I'd be using the slabs for mothers and the cubes for cuttings
When leaving the seedlings in the rock wool, for the bottom up feeding do you just leave water in the tray? Or is it water with nutrients? Aaaand do you feed regularly or just the once? So many questions 😃. I’m new to all this and 3D printing a a system as I write this
what he should of did as a test is put one with the real rockwool cubes and in the other his 2.5 Cent one and have the same seeds and see the result for fun of it and this way it would prove with out a doubt there just as good and to see which one grow better or are they the same
Hoocho Thanks again, for an informative and enjoyable segment. Can you tell me if there is a minimum buy with the Cultilene slabs from the supplier in Caboolture? That's convenient for me as well. regards.
Hi, thanks for the details and all your vids. During the time lapse, do you add water or anything or does the lid make it a fully closed system? BTW, is it water or nutrient that you use to make the seeds germ?
I was about to start using coco perlite mix to sprout because I'm doing your gutter system (with great results so far!). Do you think this is a better method?
This may be a really dumb question, but I am new to the hydroponic growing method, I have wondered if I started seeds in rock wool but ran out of room to grow hydroponically could they be transferred into the soil garden?
Rockwool isn't biodegradable. I guess you can transplant it into soil, but you will have to dig it out after plants dead, otherwise it will just stay there.
Yeah wear gloves and mask when handling those mate, I heard their dust is toxic to humans. Especially in large amounts like that. Maybe look up the safety data sheet.
Its not toxic it's more so that the fibers are so small and they splinter off. Being made from Volcanic ash You could get it in your eyes and your lungs or it may cause skin irritation. Personally I've never experienced these problems from grodan. How ever if you get rockwool insulation from say a home improvement store because it's cheaper than hydro rockwool then yes it is toxic. Back in the day Asbestos was used In the manufacturing process but now it's banned you may find It's still contains formaldehyde used as a bonding agent. That may hurt your plants and you.
@@heywoodjablome5630 only because it's been compressed. Hydro rockwool only allows water through the air pockets, that are created in the rockwool during its manufacturing process. If you were to compress hydro rockwool it too would become water resistant. This fact does not stop people from using insulation rockwool sadly.

I was going to say this,
It's recommended to wear a mask and glove when working with Rockwell!
While Rockwool is a fibrous product, I much prefer using it to fiberglass because when cut, I deal with very little airborne particles.

You can't really reuse it if the plant ends up growing into it. If a seedling dies in it, you can reuse it. It's not organic, and won't break down. It's a manmade product from inorganic natural materials, not something found in nature.
What's irrigation rate ? And how much drainage volume ? If I want do it in my home

This is made for growing plants.
Does this technique only work for hydroponics? Or can you plant the seedlings into soil?
the downside of rockwool is not biodegradable, and it should be cut under water to avoid breathing in rockwool dust.
What are they made from? and can you used in soil in the garden?
Where did you get the propagation tray and domes from?
And how far was the SF600 from the tops of the plants?
Excellent video thank you 🙏🏻

There is also slabs containing moss or coir material available. They are environmentally better alternatives to that pesky glass fiber.
Peat isn’t very enviromental friendly is it?
Oh. Sorry.
I meant _moss_ - more specific Sphagnum moss, in a product called Mosswool.

Its not toxic it's more so that the fibers are so small and they splinter off. Being made from Volcanic ash You could get it in your eyes and your lungs or it may cause skin irritation. Personally I've never experienced these problems from grodan. How ever if you get rockwool insulation from say a home improvement store because it's cheaper than hydro rockwool then yes it is toxic. Back in the day Asbestos was used In the manufacturing process but now it's banned you may find It's still contains formaldehyde used as a bonding agent. That may hurt your plants and you.
@@ascendordie7427 insulation-grade rockwool is water repellent
@@heywoodjablome5630 only because it's been compressed. Hydro rockwool only allows water through the air pockets, that are created in the rockwool during its manufacturing process. If you were to compress hydro rockwool it too would become water resistant. This fact does not stop people from using insulation rockwool sadly.
Do we separate those rockwool cubes from the seedlings to relpant them into the soil?
Great video thanks, do you know if they also supply NZ or if there is someone here similar. 12.5 cents for a 1 inch cube here
what is that green stuff on top? Algae?
Thanks for the video. How do you prevent mold attack of the seedlings? My seeds start to sprout and catch mold and die, sorry total newbie.
Make sure you don’t keep the humidity done on too long
Impossible to find Rockwall of that type. I am trying something else.
Just a question, do you think using white foam a more economic substrate for propagation?
Use it a lot , don't touch your eyes after !
