you say on top of hydrton how high do you fill with hydroton and then how high up the RW cube do you flood? how often? I got a dozen clones in oasis waiting to go into the same set upi used rock wool starter cubes then went to 3" rock wool cubes set on top of hydroton in an ebb&flo system and had no problems.............................
i recommend the others over rockwool it holds too much moisture imo.not too sure about how well the coco would do in a flood and drain... think jiffy in hydroton, ebb and flow would do well??
Squeezing rockwool is a bad idea because it collapses the fiber and it is not like a sponge and will not spring back. Then you are left with little airspace and soon root rot.I let my RW grain out and I squeeze out the excess water by pinching the little cubes.
The spirit of this thread got lost in translation. It was more focused on which medium to GERMINATE, NOT which to use for cloning.I have a new outdoor grow planned out in an ebb and flow system, based on the two tub system in the FAQ. I plan to fill the top tray with either hygromite, hydroton, or gravel, foregoing the 6 planters shown in the FAQ.
What I'm trying to decide now...
A-Which should I start the seeds in?
B-Transplant directly to grow medium, or into larger rockwool cubes and then to the medium?
C-Do rapid rooters and/or oasis cubes transplant easily into the larger rockwool cubes?
As a side question, what is a watering schedule like for each type?
do you have a grow log with the suretogrow? I bought 5 freaking cubic feet of their new size called hail. Worked ok for germination but they hold LOTS of water. I'm too much of a newb and have not done enough research to realize that I needed to have LOTS of roots coming outta the germination medium before putting into my NFT (pump always on). So far I have not killed any of my 3 babies but they have been tremendously slow (due to too much water and cheapo LED lights). I have finally gotten them under t5's.check out suretogrow if you want to get fancy.
