Nice grow I've been looking up and down the net trying to find grow diarie on the ts600, thank you for that!!! So was it Light burn? Did you find out what was it? Im currently about to finish a grow with a 3 master kush that i think are going to be a nice yield (1rst grow ever with equipment) with 2 ts600 in a 2x4 cloudline s4 for intake and t6 for outake. Got some weeding cake and cheese seeds for the next grow, 3 and 3 so now i got 6 plants on seedling stage and am thinking if to get another ts 600 to cram up in the 2x4 for a total of 3ts600 so all 6 would have enough light to develop properlyon veg or when flowering but dont know if it would be overkill for the plants.
