Greetings fellow gardeners. I’m debating on down-sizing my autoflower containers from 5 gallon to 3 gallon. I’ve had great success with the 5 gallon containers but I could always use more room in my tent. I use fabric pots, probably should have started with that. Anyway, I’m looking to pick the brains of you that have tried/use 3 gallon grow bags with autoflowers. I’m growing my first photoperiod grow now but I’ve got several autoflower grows under my belt. The photoperiod plants will continue to be grown in 5 gallon containers using SCROG. I’m hoping I can grow autos in a SOG. Any and all advice will help. Thank you for taking the time to read my first post on The Forum.
It has been a while since I grew autos. When I did, I used both 3 and 5 gallon fabric pots. I have a 3x3 and 3 gallon works great in it.

@beardless Thanks for the reply. I’ve been gardening in the dirt outside since I was big enough to walk. My family always had a 2-3 acre vegetable garden. This indoor growing is all new to me! The last couple of grows I looked at the root mass after harvest and figured I could drop to a 3 gallon but I wanted to ask everyone their thoughts. Thanks again!
When you say sog, how many plants are you thinking and what are the measurements of your grow space? When i think sog the picture in my head is basically 1 gallon pots stacked side to side or close to it.

@dbrn32 My tent is 4’x2’. I’m thinking as many 3 gallon pots as I can shove in there. With LST I should be able to have them touching or just overlapping. I’m kind of scared of topping or FIMing autos. I think I’m going to try this after the grow I’ve got now is finished, just depends on what kind of luck I have with the photoperiod plants. Right now I’ve got four plants going, 3 photoperiod and one auto. The photos are all indica strain: Granddaddy Purple, Bubba Kush, and Pure Indica. I’ve got one White Widow autoflower bringing one up the rear that’s 3 weeks younger than the photos. I may order some 1and 2 gallon grow bags to experiment with. I use Fox Farms Ocean Forest and Happy Frog in the center for seeds to start off in. I don’t transplant. It’s easier and better on the plants to start them in their final home. I’m retired so I can keep a careful eye on them. Thanks for all the help!

You should check out mattybear’s grow. He’s running 8 plants in 2x4, pretty sure they are in 1 or 2 gallon pots.

@Aussie_autos that is my thinking exactly. I just ordered some 3 gallon bags as I’ve got plenty of fives. I thought I was on the right track but a little reassurance has never hurt anyone. Thank you for your input. I truly appreciate everyone that helps me out! 
No worries at all anytime i hope it all goes well for you
