but to grow in 30-33degree temps, i have done it many times, just have to water more frequently and they are lankier . A question back at you, what are you using as a light currently in your tent, and how is your exhaust setup with intake details ?
Also to note once the plants get big enough to start absorbing all that light energy, and they start transpiring your temp of you tent will actually drop just so you know.
Example is say my current cab, if nothing is in it or small seedlings, my temps are 28-33 degrees with the lights on, once the plants grow enough it drops down to 24-28, aka natural swamp coolers lol
Edit: btw get a grow journal going, then other can follow along and help you get things dialed and then we can watch the progress
