Running Bubble ponics, beacuse of the drip thing is differnt, This is what I did in DWC which is the same, just no drip.
I raised the level of the water to just bellow the level of the rockwool cube (Like 1cm bellow it), that meanse it was covering the bottom of the net pots. this kept the cube damp and once roots started to grow outside of the pots I started to lower the water level untill it was the 1" bellow the net pot.
Using Bubble Ponics and there drip, you may not have to do this, but I can't suggest drip times for you, as I have not used the system.
Regardles of what you do, you want to keep that air stone running 24/7. if the water is left sit it will go stagnant and breed all sorts of nasty Bactira.
Good luck.
First of all, thanks for the responses they are much appreciated. (greenestheory and I are together)
attached is a crude drawing of the system.
There is no drip system, so what we were worried about is that even with the bubbles going, maybe the water would not reach the roots, which are protruding only about a cm from the bottom of the rockwool plug.
You suggest keeping the water level 1 cm below the cube and covering the net pots. Just to be clear , do you mean that part of the netpot, including the hydroton, will be completely submersed in the water up until 1cm before the rockwool?
I have heard of putting it right below the netpot, but havent heard of actually having the netpot in the water. Attached is another pic of what I am interpretting your suggestion as:
Am I correct in my interpretation?
Also, when do you suggest we start feeding nutrients to them.
