I have a grow box, not a tent. The interior space is relatively small--it's really a stealth box. The reservoir lid has holes for 4 5" net pots, and the height is around 48". On my first grow, I only had two plants (got 2.5 oz) and on my just finished second grow, I got bad algae in the res. during flowering, and they all survived, but they stopped growing, never fattened up. I got a good sticky harvest, but it's small. I figure 4 oz. I just put in 5 purple haze x malawi seeds to germinate last night, and I'm hoping that during this grow there are no hurricanes (power outage for a week during grow 1) or light leaks (fixed). I have learned a lot, but it would be nice to have a "major problem"-free grow... And a big fat harvest that I have to put in the freezer, that my friends can't smoke up too fast, that lasts and lasts....
