<clip> Plus they take up a lot less space than other kinds of watering trays.
-Hermes.
so do u recommend just buying those size pots instead of making them from 2 liter bottles?
I have to agree with Andrew, square pots fit nice and snugly together, and they are of great quality(I bought 10 of each of the 3 sizes). If you can afford them(15$), go for it, AND you'd be supporting TF!
And it's much nicer to look at.
Yogurt containers work really well, though they aren't too attractive.
A few years back, someone on the forum recommended yogurt containers for plant pots (with no warnings). I planted a bunch of stuff in them and a few months later, they literally disintegrated - usually at a bad time - like just before bedtime when you wanted a closer look at that blotch that might be an aphid .... pick up the pot and the container falls apart. Now there's a mess and you disrupted the plant's growth (or maybe ripped it apart) & now you've got to find another pot, mix up new media ....... and they also seemed to deteriorate very quickly after being under the lights (not like in a week, but most definitely quicker than a pot that is made to be in those conditions).
