Top of my Purple Punch is just 5 inches from the TS1000 and it seems to like it fine here towards the end/harvest.It seems that growers all try to keep the tent temp around 78f, 26c. If we keep the canopy temp don't over 30c, the light won't burn the plants, why not slow down the light hanging height as much possible as we can? 6 inches, 8 inches?
