this would be an excellent setup for growing lowryder or smaller plants. But then again, any plant can be a smaller plant if you grow it that way! Check out how it is coming along with only 2 plants in there! This is the same grow box as earlier, meaning it still does not have any active ventilation. We did however add a passive carbon filter (see top in picture) We will flower in the next week so we are working out the ventilation logistics. We are thrilled with the results thus far and can't wait to have indoor soil AND hydro grows running at the same time. Heat stays around 74 F and about the same when the light is off and the doors are shut.
