Hi everybody on R.I.U. My plants are 6 weeks old in an nft hydro system and I was thinking if I can switch to 12/12 for maybe 3-4 days to determine sex, then switch back to 18/6 and then take clones of the females and veg the clones for maybe 2-3 weeks. I don't want to clone all the plants and...

I have lowered the net pots a bit so that the water level almost touches the net pots, maybe 0.5 cm (0.19 inch) between water and pots. Does that sound about right? And I have also pushed the rock wool cubes as low as I can in the net pots.. And one question: is it not ok to blow the cold air...

So it is a heat problem then? Would it not fix it if I just blow more air through the tubes so that the root zone gets colder?

I have already used bleach on large parts of the room including on all the mold i can see, but some parts are difficult to get to. yes I have exhaust fan and planning to buy one who is able to change air 30 times an hour, I feel confident that i can keep RH fairly low but I am afraid if mold...

Hi everyone, i have got leaks here and there in soon to be my grow room (hopefully). But there is mold growing on walls and in some corners, i am able to get a lot of ventilation and possibly a humidifier and of course I remove the mold as soon as i see it, but it will probably always come back...
