Amazing! Your picthres have disappeared for some reason though!? If possibly upload them to RIU so I can show them to my disbelieving friends that think rock wool is crappy!? Thanks!Thank you JDMase!
The plants vegged for about three weeks. I chose the big blocks over slabs because they are easier to prepare (lay 'm on the floor and go) because of mobility and since i water by hand i like a bigger medium. This is my first run on big blocks and i couldn't be happier. There is absolutely no more forgiving medium i have run across and i neglected the plants big time.
Looks like a pretty good system! I recently invested in a gravity drip feed system. My plants liked the regularity but it needs to be topped up as I realised it only gives a tiny 1.2 litres PER DAY. Definitely not enough. Ah well, it got me by whilst I was away!I upgraded to a ebb and flow system with two plunger pumps and a water reservoir of 200 liters. I pump the water in the leak tray until the rock-wool big blocks are flooded and pump the water out again.
The cubes suck up as much water as they can retain, so i only have to flood a few times a week.
What is your view on non-recyclable plastics?I have not tried rockwool and never will probably as it is not a renewable or an eco-friend option at all. .
That's leaving little oxygen at all.The cubes suck up as much water as they can retain, so i only have to flood a few times a week.
That is no problem for DWC neither.That's leaving little oxygen at all.
Wow i kust started rockwool ur pic is insane wow brother u know ur shit what stran is that kick ass grow brotherView attachment 3815701
Works for us 4 inch stacked on a 6 inch set on a drip tray hand watered with supernatural brand nutrients. Many many ways to utilize rockwool
Top feeding ANY rockwool from the top in a drain to waste setup IS IDEAL. And much more forgiving than a flood and drain recirculating system. You got it backwards.If you can get away from it that is definitely a plus, but i have noticed too that feeding the blocks from the top with a drip feed system is not ideal.
The ebb and flow system i use is not at all expensive, what you need is a leak tray that is waterproof, a water-reservoir and two plunger pumps. One to pump the water in the leak tray and the other to pump it back into the water-tank (which can be set with timers too). Make sure you flood until the blocks are under water, so they get completely saturated, which is a huge advantage of this system compared to drip feeding in my opinion.
You must be growing 12 footers! can grow a big plant in just one hugo.Is it a bit late to write on this thread lol I’m a new grower aswell and I love these Rockwool cubes , I just switched over to the 4x4 cubes stacked on top of the 6x6 and stacked again ... lol but so far I only water about 2-3 times a week which is awsome! Anyone else still on this thread ?
