How many autos??

I would never get more than 2 in that space but for whatever reasons my autos are always over 10 oz dry , from what I see in here most people would get 4 in there comfortably. You could throw in 4 seeds and see what happens , leave it up to the Auto gods .

You'll get more than 3. That's just a waste of time. Unless your pulling 200+ grams a plant. And in reality with autos most of the time that's far from reality unless your running rdwc or dwc. I've had nearly 200g from coco but that was a 1 off. And I wasted my time taking and bringing to harvest all of it. Which I would never do again. You'll find a ton of growth that will have lil hairs remove them or anything before it flowers. As it'll just be larf. You have a decent size tent so you don't need to focus on quantity focus on quality trust me I focus on quantity big mistake. I have 8 autos that would fit fine in a 2x4. I actually have 8 autos in or around a 2x5 and I've room in the middle for at least another 2. And as this is your 1st

Well I got 5 autos in a 2,3x2,3 70x70cm. Would have been better with 4 so I'd say you'd easily fit 8. Good luck .

I’d recommend 3 maybe 2,but that also depends on the seeds you want to pop, some autos can get pretty big! I wouldnt do more than 4 since I tried 2x auto sour diesel that didnt get that big and still I had to remove one cuz they werent fitting into that 2x2.

0 auto's suck. Cheers!
