I was able to get the 1020 trays by Bootstrap Farmer and am quite pleased with the quality of thick, sturdy plastic. I'm able to fill the whole tray and carry it very easily on the end with both sides balanced without any signs of bending.
As for quality white pots, there's these ones that a good number of members here likes to use and vouches for them, which is this one: https://www.amazon.com/Active-Aqua-Squa ... 421&sr=8-6
However, I don't really like the holes on the side which I'm sure is an easy fix. Bootstrap Farmer also sells white pots which is this one: https://www.bootstrapfarmer.com/collect ... astic-pots
. I'm positive that they're the same great quality as their trays. I'm interested in trying them out but it's a bit expensive and am in no rush of needing larger sized pots. Maybe next year for my mother plants is when I'll be able to give my input on them.
