weedhound: very comprehensive link on the rockwool, thank you ;]
The next reservoir change (basically once I can collect my 40 gallons), Ill stick to just the grow nutes, and calmag (and probably 15 drops of superthrive heheh)

40 gallons seems ridiculous for 4 plants.. Too late now however but next grow I think I'll be sticking to 5" net pots, just a little bit over the tray so that will only use about 20 gallons or so.

Great idea on the trash can for water storage, I was thinking of saving each milk jug I had but that would take way too long to save 40 milk jugs.

Opie: I'll consider anything that could be concieved as negative well deserved. I made a lot of mistakes early on due to mostly impatience. I'll just try to do things correctly from here on out. Good news is, the one thats showing a root has maybe 3 or 4 tiny ones still in the netpot that are about to pop out. I'm crossing my fingers and hoping that they will explode pretty soon.


Oh yeah, the 250w HPS light is about 16" away, I'm thinking I could bring it down to maybe 12"-14", thinking some of the slow growth is not only contributed to my mistakes early on, but also possibly not ideal light strength.
