It will vary. My first use of those were with Autos that got stunted when seedlings due to starter soil Ph being too low and caused problems with them losing some time growing in veg before they started flowering. I had 2 of the 45 gallon pots each with 3 Autos…can’t remember the yield but wasn’t bad but wasn’t phenomenal either and still had plenty of room in them for more plant or growth as they weren’t covered…soil wasn’t covered with branches like the middle one is now.
Autos do what they want when they want but Photos you have control as to when they flower and if issues you can extend veg time to correct issues.
This go I have 3 of the 45 gal pots with 3 photos in each.
The one in the middle has 2 gold leaf and 1 blue dream and they are getting huge and are the youngest planted about 30 days after the other 6. The other 6 I had in there with a couple photos that were finishing up and those went into flower and had to reveg back from flower so that really stalled them out but are now coming along.
My guess … and it’s only a guess is that those 2 gold leaf will probably end up yielding about 12 Oz dried in the end and the Blue dream will get 4-6 Oz dried but again it’s kinda early to know…just a guess. Again if I veg them longer they get bigger and usually end up with higher yields so you have to decide how long/big you let them get and if the increase in yield is worth that vs flipping earlier and getting more harvest per year etc.
If I had it to do over again those gold leaf could have each been in their own 45 gal pot and would have covered it…right now I’m fighting keeping them within reason footprint wise between each other and the other one in there and the other pots.
A couple grows ago I used 7 gal pots and with 7 photo plants I yielded about 3 1/4 to 3 1/2 Lbs dried combined but I also had 2 autos in there as one of the photos ended up being a male.
An idea of them above link
I’ve gotten 8 dry from an Auto in 3 gallon pots and I’ve got 3 dry from Auto in 45 gal pots…just saying
