Small space grow
Puffdamagikchillumstarted grow question 1d ago
If you grow in a 2x2x3ft tent and grow autos I'd like to hear and or see how you manage your light distance to tops of colas. I'm using a blurple 390w from wall. Will it burn em up? I have roughly 5" left between light and tops.

Honestly, that's pushing it—blurple LEDs can be pretty intense up close, and 5" is definitely in the danger zone for light burn. You might start seeing bleaching, curled leaves, or burnt tips if it hasn’t already started. I’d recommend some quick LST or supercropping to lower the canopy a bit and give yourself some breathing room. If possible, try to raise the light, even if it means zip-tying it directly to the tent frame. If your light isn’t dimmable, you could even consider reducing light hours slightly to bring down the DLI. Keep a close eye on those tops daily—better to catch stress early than lose your colas late.

It's a fairly short distance, but it happens that the girl grows taller. The distance between and the tops of the plants is optimal from 30cm to 50cm. As we've already discussed, it's not always possible to keep this distance. I wouldn't solve your distance yet (according to the picture), the plant shouldn't even grow too tall at this time, rather it should gain in buds. If it were to get even closer to the light, I would GENTLY bend it (NOT HST) and use a string to stretch it towards the light, so that the girl doesn't burn directly, but is still in the light spectrum. This has happened to me several times. Specifically in my Sunset Sherbet Auto diary.

agree, not familiar with that light but turn it down if you can, that's a lot for the small space unless you can keep the plant short. if you grow a photo you can could switch to flower at 3 weeks to keep her shorter along with LST. My auto that has been LST is still 20" tall, still has almost a week of stretch left and light 11" away which would leave 5" in your tent. LST is an art and requires daily attention, the more you grow and incorporate it you will get the hang of it and should be able to grow one plant in your setup.
