It varies ... light aerated mixes perform well.
Hydro / DWC seem to make larger autos as roots explode in these setups.
Some are strain specific and grow large ( Big Bud XL / NL / Mephisto / others )
One trick to getting them to VEG better ( start at a high cycle 20/4 or even 24/0 ) plant will energize growth faster under long
cycles THEN when transitioning to sex / preflower either leave cycle or go to 18/6. You want that shorter veg stage to get all it can get.
That’s why I just let medium feed it and light power it. I no longer feed ( bottle ) during this stage as a well ammended soil will do the work. Less chance of fuck up.
Once you start burning , overfeeding , overwatering, stressing these autos during this critical stage , you will notice less than stellar
returns. Autos do not have time to recover from any mishaps. Sativa leans do benefit from LST and some minor topping , but that’s about it. You can also Bend her over for a simple tie down ( 3 nodes growth ) and lateral branching will now grow upwards .
2-3 ounces per smaller autos is about average ... some can push 100 / 200 grams and better. Seen some outdoor autos really get large in 20gallon bags . Breeder estimates are to be taken with a grain of salt on yields ..... some say 600 grams ... but expect those are outdoor greenhouse monitored grows ( or lab ). I grew 4-5 foot indoors so it’s possible I guess.
It’s trial and error period . Some breeders are better some are bunk. You can have super autos that have strong parental
lines and shit like dwarfy strains ( perfect for SOG perpetuals ) ...
I recommend minimum 3/5/7 gallon for most indoor —— 1- 2 gallon ( bags ) for SOG grows.
They grow pretty much in any container ....
Solo grow for seeding / fem pollen experimenting....
Would have showed you more but since this site update ......
BUT All my journals are pretty much gone apparently.
Pics and all .... FFFFFUUUUUUCCCCCKKKK
Just remember LESS IS MORE with these. GL
