I use rockwool. Try growing with all mediums. There is no best medium. (except organic soil)
(I see why you said that... because of the algae.) I use plastic covers on the top of my rockwool. If you do not you do get bad algae. The algae has never done any harm to me.


T5's would work good. Not as good as a HPS. The T'5s would really help with heat issues. The T5's would look good in your setup. LED's are nice but pricey. I would do some research before getting lights. I love my HPS. Most people do start out with T5's or cfl's.
demoreal Reviewed by demoreal on . SOG question Im about to start a SOG setup and I have a question. I have to hand water the babies cause i have no room for anysort of automation. i picked up 6" RW cubes and have four side by side in a tray. i dont want to put just the RW in the tray cause im afraid of algea forming on the bottom of the tray. i was wonderin if i could put about 2" of lava rock on the bottom and place the RW on top of that. would the roots grow together and fight with eachother? There wont be any veg time, once the clones Rating: 5
