this might sound like a stupid question, but whats the difference between using the airpots and using regular pots? i was telling my bro about them and he was like itd be interesting to see a side by side grow of both of them like a 15 liter regular pot and a 15 liter airpot. do one of these threads or journals exist on this site? btw those are some sweet looking plants, but when you say upgrade the modules you mean upgrade the LEDs or the drivers?
