I like using Solo cups too. I transplant all my tomatoes into them after they have their true leaves. I poke holes in the bottom and the cups are nice and big for a decent root system. Not only that, I can write directly on the cup with an indelible marker. No more lost tags!
They are also a nice size for starting things that you don't want to transplant more than necessary.

I like your site! Good luck with your seedlings!

oh - I did have a giggle when you described yourself and your roommate as "collage students".....

Trishcuit, I find the convenience unparalleled, and I usually try to minimize transplanting, so their perfect for me to just germinate directly in the cup. I found out last year though that transplanting isn't all that bad... I think they compensate for whatever stunting that happens with the added space for the roots, which allows them to grow a lot faster than they were before transplant.

t-bird, Whoooops :0. Thanks for pointing that one out. It pretty much sums up my collEge experience though... misspellings everywhere! I'm in more of an engineering program, so spelling isn't exactly my forte (although I do like to read and write a lot). Thanks for the encouragement. I just updated the site with some pictures of recent growth. Check it out :)
