I really like SQUARE pots and mine look similar to yours Oakley!
I have 3" green square ones (from Greenhouse Megastore) that I start off with and I plant up to 4 seedlings per pot, then I pot up into taller square ones. These were all saved from various perennial acquisitions by me or my friends. (I ask a couple of friends to save square pots for me
). When potting up, I also use waxed cartons (that creamer comes in) so that I can give some plants away and not worry about getting my pots returned
.
I still don't have perfect trays for these pots. I bought some opaque ones (with turquoise handles) from Walmart which fit quite nicely on the growlight stand, but there is wasted space and the middle is raised a bit so they are not perfectly flat. When I need to put more pots under the lights, I have to put them individually on the growlight trays which isn't really such a big deal except for unloading.
