I've always purchased seedlings but this year I've started to grow some of my own stuff before moving them outside.

In the past I did:
eggplant
green peppers
tons of tomatoes
lots of herbs
strawberries
garlic which didn't grow but I did end up with 1 giant leek

This year my plans are:
green peppers
zucchini - my seeds are doing awesome!
cucumbers - my seeds are uber failing. I've never grown them and don't know what to do so I'll look for some seedlings
lots of herbs
eggplant
not sure what else yet

Anyone have experience with cukes from seeds?

Everything I grow is in big pots in the backyard, not large enough to build in a veggie garden, but I will in our forever home!
