Can TGA strains handle intense light?

My vortex seems to get light burn easier than other strains I've grown. Does TGA gear get used to low light conditions during the breeding process?

Dunno but my Querkle does seem to bleech out just a little after 6 weeks under the HPS. Could just be natural flushing but seems to be light bleeching.
Nothing to worry about tho.....

Check out the vortex buds, closer to the light I get this....


I doubt I'm over feeding.

curling like that would be from the heat and not the actual light itself.
Unless its a different issue altogether.

Room temp at 82, leaf surface temps get up to 86. I've got another round of vortex going, but not sure what to change in an attempt to get flat happy leaves. It does appear only on the buds closer to the light.
hmmmmm

obviously if you have buds closer to the light you have differing leaf temps, not sure how you would even measure that (laser temp reading?)
86 is pretty high anyways.
Light itself will NOT curl leaves, it WILL bleech them however.

I use an infrared thermometer. 86 seemed ok considering I'm running co2. I can run the lights closer during early flowering without any ill effects, this up curling kicked in about day 30 or so. thanks for sharing your opinion :)

You're not having a "light intensity" issue.
It may be something else, but the distance from the bulb does have a direct influence on the degree of curling. Perhaps it is just the normal finishing response for vortex. I've cooled down my room and vented hoods a little more, 77 room temp and 81 max leaf temp. We'll see how the next batch do.
It seems odd that I would have heat issues at 86 degree leaf temps, 50% humidity, and co2 boosted. Bud growth is still adequate, but I would like to figure out how to grow vortex with out curling the leaves. It's the only strain I'm growing now, I'll keep at it till I get her dialed in.
