LOL, Rick ! If those plants have 4-5 leaves, I'm thinking they must be in something bigger than a plug or cell...
@Maxcaviar, help us out here!
My main concern is that -- depending on where the OP lives -- there isn't enough time for "starts" to grow out.
(if I don't start squash in April in the greenhouse, to plant out in June, there's no way they would ripen before we had a freeze)
