Do you run a staggered grow blue, or just like 1 round of plants at a time?
I just run the one at a time - It's just much easier that way, and with my limited space, the results are always better with one plant filling the tent. And less nutritional requirements and messing about - less chance of mold ... less leaf matter to get rid of at the end .. lots of benefits for my setup!
I could probably squeeze 4 grows a year .. maybe 5 if I were to get lucky with finishing times, but i only really need to grow 2 ... so sometimes get a 3rd in for variety!
