I have been growing for 50 yrs. but first time with auto’s, root balls seem very small does this happen with all auto flower.
These root balls are from amnesia haze autos. From left to right (all 3 gallon pots) Vivosun, Vivosun and smart pot. The small root ball in the middle produced really nice quality dense buds. The plant overall was compact. The one on the right produced the most weight
I have had small root balls to massive ones that stretch 8 feet in length while in a 5 gallon bucket filled about halfway with FFOF. Switching to 15 gallon fabric pots as I type this.
