I would.
2-4 inches most of the time. by the way after the t5 they will go under 600w hps
Right on I'm doing the same just set up a smaller veg tent with t5 and my flower tent has the 600 hps
Sounds like we have the same grow setup. I have a 4 ft 4 bulb T5 in a 2 x 4 tent for veg and then a 4 x 4 with a 600 watt HPS for flower. Works like a charm. The T5 is great for vegging. It's got to be the high output bulbs though.
Yeah man so easy to keep temps and humidity with the t5.....how do they like the transition from t5 to hps haven't done it yet do you keep the lights higher at first
Keep the lights high doing the switch and have a lot of air moving. Lower the lights gradually over a few days and you will be fine.
and watch for stretch. so far all of mine have stretched lots going from t5-hps minimum double in size and one crop tripled (sativa)
Yeah I hear ya on that one lol
