Growing in a prefab grow cabinet 18"x13"x48". Temperatures are way to high. The fans were not strong enough to move air adequately. Later on in the grow I assemble a makeshift mini a/c that takes care of the temperature, but struggle with high temps for the first few weeks.
@Moneymitch125, that's an AN product right? As soon as I finish off the GH stuff I bought I was going to switch over and give a few of their ph perfect products a try anyway so I'll pick some up, thank you.
