I have hung the lamp all the way up and am now trying to keep the shoots at the right height, but I have brought the upper shoots to the right height by super cropping, but I hope that the stretch phase is almost over. The predatory mites have now done a good job against the fungus gnats. I'm going to install an exhaust fan this week to get rid of the humidity, and I've bought an air filter for the apartment that also has a built-in activated carbon filter to combat the smell.
