i was thinking that was the case( over watering) i get get abit paranoid when i start seeing the soil drying out...i feel the need to give them a spray...
im not sure whether i need more ventilation, i have 9 x 120mm x 35mm arctic cool pc fans running inside the box, 4 on 1 circuit and 5 on another, i have fresh air being pulled directly from the outside of my garage and the warm are directed into the garage itself....once i get to the satge when i can switch my hps on all 9 fans will be on, i tested the box for week with my hps on 24hr just to get the temp perfect ( i did have to add 2 more fans)...but it runs very stable at a considant temp, but once the temp outside starts dropping dramatically i will have to knock the fans off 1 by 1....
theres not a chance in hell the all 6 will fit in there once they get to a decant growth rate, im hoping to pull the best 3 out from the 6 and use them untill they need transferring to a bigger room.. the other 3 a dude across the street will have them........i really need to start getting my arse in gear, i defo need a ph tester ( i know i should have 1 already !!!!) but i think the next try for my is gonna be rockwool cubes from what i hear they are pretty much the bees knees......
stay strong
