Styrofoam egg cartons for starts

I'm new and used Styrofoam egg cartons to start some seeds. I had a good turn out however when I transplanted into yogurt cups they were very wet even though each cup had a slit in it. Is this a possible issue? Is this a benefit? Do I adjust watering? Do I make an actual hole? Should I just start in yogurt cups and nix the egg cartons? I'm Learning so all suggestions welcome. Ty

Hi Rebecca!

So very wet and saturated soils could be problematic especially if they stay that way a long time. I would hold off on watering until things dry out a bit. A hole on the bottom of the egg carton cavities and also a few holes in the bottom of the yogurt cups will drain better than slits and help resolve any water logged soil. I think you certainly could skip the egg cartons and start directly on yogurt cups if you wanted to. Hope this helps and good luck!

James i think I will do alot more of the cups and make holes instead. Ty

I’ve found that the styrofoam cartons aren’t really big enough after a week or so, though I’ve successfully used the paper cartons to get a jump start on peas as the carton can be cut apart and planted directly in the ground.  Yogurt cups and pudding cups are great!  I usually stack about four together and drill drainage holes in the bottom.  

I've ordered some 2" hydroponic cups to start seeds in.
I saw video by Larry Hall( I think) where he uses 3" cups, with great outcomes.
He really insists that 2" cups are too small,  but I'm just too cheap to not try.
I plan on putting them in a tub and adding potting soil in and all around each cup.
About an inch from the bottom of tub,  I'll drill over flow holes.
A very short length of hose will be a fill tube
After soaking the soil I'll sow seeds in each cup.
The idea is to have a way to evenly water the seedlings from below, plus the roots won't circle and get bound up,  because they can easily escape the net cups.

I have an idea for making seedling cups from nylon screen, to bring down costs,  but that it's pretty far from realization.

I like the hydro cups in theory because of allowing for the roots to be able to grow past the pot. Seems like a nice idea
