old thread, but OP is running a sealed environment w/ co2 supplementation and is no stranger to proper room builds.

I believe that some cultivars just don't like the 80-85F temps despite the co2 supplementation. I'd maintain a day temp of 76-77F or so and see if that improves anything.

My mentor so to speak has also warned against too low of temps during the night cycle. A lot of people accept the mid 60s as being ideal, but with certain varieties (more sativa dominant phenotypes) I've been told to maintain warmer night temps and keep the differential as tight as possible. Say 70-72F night temps with 76-78F day temps.


Vostok, OPs pics of his foxtailing are in post #23.

I also agree with VG that sometimes foxtails are perfectly normal and a natural expression of that cultivar.

ive seen outdoor plants foxtail,it seems to be a genetic thing as well as enviroment.

Ty for posting this you just answered a question of mine, and prevented me from making a little mistake.

Can someone explain with images what exactly foxtailing is?

this thread is filled with pics of foxtailing.

only time i see foxtails are.

a.)too much nitrogen too long
b.)too hot
c.)genetics

it's usually some combination of a or b.

All strains i grow end up foxtailing to some degree. Even ones that would not for most growers. Is this because of the ever present 65%+ Relative Humidity in my room? Are the flowers elongating in order to protect themselves from mold?

The only part of my room that is not dialed is the humidity level. I can't get the humidity below 60% ever during lights out in flower. The expensive santa fe dehumidifier i bought a few years back could never do the job, just have too much plant matter in too small an area. I installed a 10 inch max fan to exhaust during lights out, but the condensation was causing issues and i had to ditch it. If i thought a better dehumidifier could solve the issue, i would consider purchasing one. When i grow sours and such they become a major pain in the ass to trim, and their appearance is altered due to all the foxtailing. By the way, whats the proper scientific name for said foxtailing? I'll read up on google once i know that!

Thanks for checking out the thread and have a nice day, would ya.

Lots of sativa genes in a high IR environment.

I don't see foxtails on cuts that don't foxtail even under really high IR.

The only thing you can do if you want to keep your cuts is use lots of blue light and take the hit on yield...there are growth hormones, but thats not for our business since we are legitimate people not looking for easy wins
