First Grow: Heat Stress

I’m growing 7 autos outdoors in a greenhouse. I have 5 white widows and 2 amnesia haze from King Crop Seeds. They are planted in 7 gallon fabric pots in a 50/50 mixture of Miracle-Gro Nature’s Care Organic Garden Soil and native soil (where I’m at it’s a more sandy soil) with hella perlite for drainage. I water them daily and check them for pests which I’ve only had one problem with and handled quickly.

I chose a greenhouse because where I’m at weather is extremely unpredictable and heavy rains are common. More likely than not at some point in the next couple months there will be a hurricane or some other natural disaster that destroys tons of shit, it happens every year. I also liked the fact that I had more control over the environment of the plants.

My white widows were planted 4/19 and amnesia haze on 4/28. I’m worried that they are super behind schedule. They still only have a couple of leaves and they’re small. The edges of their leaves are cupped and one even has a small dark spot on it. I’m almost 100% sure that it’s heat stress, but I’m not sure what to do about it or if it’s too late anyway. It’s really hot where I’m at, this week has been in the low 90s. The greenhouse is so hot and humid that I end up drenched in sweat after being in there for 20ish minutes. The tent is in the middle of the woods with no access to power so I can’t use fans or anything to try and cool it. The only solution I see is bringing them outside which I worry will cause more problems for them (if they aren’t too far gone already).

I’m sorry to bother you guys I just really need advise before I make a decision

Again, I’m really sorry guys.

A greenhouse in those temps without air circulation will cause you problems that will only get worse throughout your grow. Get a solar powered fan. They'll recover.

Thank you drsaltzman!

These will also make a big difference, as they heat the gas in them expands & opens the window.

Somatek, that looks awesome! Unfortunately that won’t work with the kind of greenhouse I’m using (plastic), but that is really cool and maybe I’ll be able to use it in the future. Since the temperature in my area has risen so much i rigged my flap door open and covered it with mosquito netting to hopefully keep bugs to a minimum. That has overall helped with the temp a lot so I’ll just have to wait a few days to see if the girls start looking better.

Thank you coreywebster, this website has been super helpful and I’m glad that the growing community is so accepting and willing to help others.
