Yield depends many factors including grow environment, genetics .
SOILESS , hydro , DWC , Hempy grows the biggest autos. Outdoor grows can get pretty big too. Average pot sizes range 3-5 gallon containers. Bagged soil is the easiest , but custom soil mixes work well too. Any bigger container is a waste with soil medium .... but you can get some big ass girls with Hempy , octopot , Rez grows.
The more compacted the soil medium , the worse it roots. There limited veg stage needs to have as aerated a medium as you can get. Peat mixes work well plus adding perlite ( 25-30 % more ).
Yields vary from a couple ounces to more. You can top “ some “ strains at least once. You can LST them to open the mids and lower area. The key to more bud is breaking the apical ( Xmas tree ) shape that they normal shape to. Autos can run different even from the same seed stock , different structure, different feed requirements, sensitivity to stress , etc. ........ that’s why it just better to let them just express naturally. But simple tweaks can help ... like the LST .
Overfeeding , overwatering , manhandling and other unnecessary things that may slow it down will impact the end result. It takes a little practice to see what they like and don’t like.
Some mini scrog them , some LST the stalk to the side ( for lateral growth ) , tomato cage them ( to help shape ) ... etc. ....... SOG bag grows ( 1 gallon bags ) or black pots .
They are perfect for perpetual growing ... staggering a couple weeks between so you can harvest every 3 weeks for example.
3 gallon pots ... soil
5 gallon .... soil
It really surprising there is still a lot of hate about them ....sure you get duds , but you get good meds out of them too. Most of the crying comes from those that can’t grow them properly, it’s a god damn plant for crying out loud .... lol.
