Ok so I have done the "research" and now I want to ask the people who actually grow in a home setting. I have my seeds in the soil waiting on them to sprout. More info is this, I know the Ideal temp range is 68 to about 77 degrees Fahrenheit, and warmer durning germination, But the lowest i have seen in my tent at this point is 84.7F durning lights on. Humidity runs about 66.5% to about 75% depending on if I put the humidifer in the tent or not.

Questions:

Is a temp that is gonna be around 84 to 85F going to be a problem for my grow?

Is Humidity in the mid 60s to mid 70s going to be a problem for my grow?

Aside from sitting a frozen jug of water or 2 inside the tent, I really dont have any way to cool it nor can i afford to buy an Ac unit for the tent.

Based on yalls personal expierence at home, do you think my temps and humidity are going to be an issue?

Like I can deal with maybe some stunted growth or the plant not getting huge, but if those temps and humidity are gonna kill the plant later on in late veg or flower stage I need to figure something out to cool the tent.

Are you exhausting into the room your tent is in?
If your humidity is that high without plants in there, it will be raining when its full of plants.
I only grow indoors in the winter. The normal lack of humidity here that time of year, plus being in my 63 degree basement makes conditions in the tent manageable without anything aside from the exhaust and light.

Yes, I have no way to vent it anywhere but the room its in. It is winter here in Ohio, and the humidity outside the tent is reading at 59%. My basement where the tent is, just happens to be fully furnished with heat vents, so its about 75f Down here in the winter.

You'll be fine at ~85 with a LED lighting setup. Usually the offset for LST is -2f degrees...which really is a good sweet spot for lights on. If you can keep the temps within 10 degrees of that with lights out you're good.

Keep a fan blowing at the top of the canopy and temps should be fine. Check the actual soil temps as that is more important IMO. Around 76-78ish which should be the case based on your data. As far as humidity, if I am around 60-65% I am good, much more than that I have seen powder mildew but that also could have travelled with the clones.

I dont think you will have any problems in the mid to high 80's, and possibly low 90's. I know my tent would jump up there during the grow in summer when I didn't use LED lights. The one thing I would be concerned about is the high humidity during flower if the buds are dense. You can get mold so make sure you keep the air circulating out of the tent.

I have an intake and exguhst fan plus a fan inside the tent moving air.

That's for HID's. If you're using LED's, you should raise the temps to 82F or so because it doesn't produce the same infrared heat that HID's do. It's all about leaf surface temp.

Your worry should be the humidity come flower and your setup of recirculating tent air back into the tent.
