I can’t even confirm that. It was just something I read. I haven’t seen it myself. When my closet got too hot, I just saw some leaves wrinkling slightly, maybe a little droop. I think they just got dry though.
But I agree, longer internodal stem lengths gives you more flexibility with training. But if height is an issue, stretch could be a problem.
I don’t think height will be an issue. I’ve got 6 ft to the light. I’ve had issues in the past with drooping. But water usually cures that. It sounds as if I’m set to go.
There’s one great way to find out! 
Drop those beanie babies!
Tomorrow ill grab some insulation from work and get these clones rolling. Sorry @PurpNGold74, no beanie babies. Next seeds to drop will be legit ordered beans.
You think 6’ is plenty of room until you take into account how close you can get your light to your plants without burning them. Most are around 18-24” So 6’ becomes 4’ quite often. Don’t forget about the stretch and veg too long. Supper cropping can help with height issues, to a point, before you have buds everywhere and on top of each other; and then grow too close to minimal light distances.
Shoot, I also forgot to include the height of the grow bags or whatever. This further reduces your grow space height as well.
Well that’s my $.02 for the evening. 
I appreciate it. Ibe got seven foot to the ceiling, but I figured the light hanging a foot down. If I flower two plants at four foot tall that should yield a decent amount. Usually I train my plants low. I don’t need to grow monsters. Although it would be great! With two separate rooms I can keep two small clones, two ready for flower, and two in the flower room, with two months for each stage. I figure that would keep everything in order.
Although, time frames usually don’t fly well with me.
There are tons of outdoor growers that have dealt with 100+ temps and there’s are just fine no stretch just requires you to give them cool drinks to cool down roots and more often
Do you think directing the intake air directly on the pots would help keep the root cool?
Sorry I’m so late to the conversation. CO2 can help the plants inside handle the heat better than without. Yucca root has also been known to help combat heat stress.
Not that it will happen, but expect some foxtailing with the higher temps. Not as pretty, but it’s not a problem unless you’re selling.
Hey, if you can’t make it on time, make it when you can! Hahaha My flower room has a.c… So there won’t be any foxtailing. But about the yucca… Could I dig some up, slice the tuber, and boil it? Use that tea as water and add nutes as normal?
I don’t think boiling it would be a good way. I only say this because I think it may kill the good properties.
I wish I could remember who was using it so I could tag him in.
I would think you could mash it and then place the mash in a bubble bucket for a couple of days. An aloe leaf in the mix may help too, but @Mrcrabs would be more help in the realm of using aloe.
Hmm…maybe @pigSquishy would know about adding Yucca. You would be amazed with the info he has! Lol
I think additional CO2 would be the easiest route to beat the heat, but let some others give some input. Outside, I just don’t think about it.
I see @peachfuzz is active! Hey, Brother! Do you remember who to tag for the Yucca info?
Ive got the cylinder for the co2, but I refuse to use it until I can get a meter/controller. (Which isn’t going to happen anytime soon, unfortunately.) Damn you adulthood and your shitty bills!!!
Maybe dry it down so it can be powdered.
Not off hand @FloridaSon… glad to see you around my friend… 
All the advice you have given so far is solid…
In veg I really dont worry about air temps… i run rdwc units with built in chiller… the only thing i try to do is keep my humidity around 60 to 75% and water temps no higher then 75 degrees and my plants go crazy… especially if I’m adding co2… i cant keep up with them…
But I really dont worry about air temps… my veg room is running at 87 deg right now and my plants are growing like weeds… 
That would be better than boiling it.
Most of my online time is spent in the lab forum now. With my connection problems I have to decide where to spend the most time and the paid site won. Lol
Nice to “see” you again too! I’m usually here long enough to catch up on tags, but that’s about it anymore. Learning some good info on living soil growing, so been busy over there.
Until next time, Brother…
I use this:
NPK Industries RAW Yucca 2 oz
