so i have 2 40 watt hps's in a 3'wx6'lx4'h
good air flow with temps never higher than 85 (i live in a HOT DRY aera)

you gotta buy some hydroton man,

you cant just use rockwool cubes i mean its working pretty good but your roots are being exposed to the light, and thats not good.

get hydroton rocks and just put them on top of the rockwool cubes and you should be good. you can

also, push those roots down that are already popping out too :)

gotta agree you need hydroton ! beter still is to root on it using an aerponic cloner straight into hydroton.and if useing rock wool the smaller the better that way the roots will get into that lovely arlita and get plenty oxgen

be sure not to let the rock wool become soaked or it could rot those roots

THANKS! im looking for all the comment's i can get!
but for the light issue im using lid's on my net pots and the lid's are over sized so not much chance of light geting in there i think the only way light is geting in is from my thin white bucket's

for the hydroton im trying to keep supplys to a minium and just plain simple (im trying to teach a few friends that soil is not the only way and im trying to get them set up as simple as i can...personaly i have never had a MJ plant live more than a few weeks in soil)

and the wet wool..it stays moist from the humidity from my splashing bubbles in the water and i dont overfill my buckets i try to leave a few inchs of air so they can breathe

THANKS AGAIN please leave me more i wana learn as much as i can from as many people as i can

if u want more pics of my room lemmie know


P.S how does everyone feel about CO2? use it or lose it?
isnt it a pain to make your room so controled for air flow and saturation of CO2?

Someone already said it but tou should lightproof those containers. It can be easily done with a layer or two of duct-tape. I can see the roots through the tubs in your pictures even so it's probably a "good idea", as Martha would say. This just helps eliminate the growth of algae and other bad things that require light to thrive.
