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.
I have almost the same thing going on here. I actually got the idea from the FAQ that you linked. I used the small 1.5" RW cubes but I have been wanting to try out the other starting mediums. I really don't think it will make a difference either way. Anyway I hand water the small cubes on a plate under a small CFL until my I see root coming out the bottom of the RW cubes I use. Then I just stick the small cubes in a 5" netpotfilled with hydroton, and stick them in the top grow container that is also filled with Hydroton. Here are some pics to show you what I mean.
You can see thatt there are 2 cubes in the first pic that is just for right now. Of course when they get bigger they will each have their own net pot. Also you will see in the secong pic that I have only one plant and it is sitting in the net pot in the container of hydroton. So there you go I hope I helped.
As for a watering schedule I water them every 4-5 hours and they container floods just below the RW. Also I make sure that the small RW cube is covered with pellets to keep the light off the cube. I have a CAP timer that is set to flood for 30 seconds every 4-5 hours. When they are first put into the system I only need to food for 15 seconds. As the plant gets older and the root sysem more robust I need to increase flood time to ensure the root mass is saturated.
Thanks for the response! haha. as promised +rep
Helps a bit... gives me an idea what to expect with the rockwool. Anybody got anything for the rapid rooters or the oasis cubes??
side note... is that used as an oversized hempy bucket??
