Hello DrBreeze Hope your having a good day & thanks for your feedback.
In answer to your question, other than having some seeds from product I have bought, the only other real expense involved was the purchase of some plant food. I did find out one thing tho, as they grew, I have been regularly been removing large sun leaves to allow more light. Don't know if I was right or wrong by doing so. These plants have been growing since about early May, took a gamble on any late freezes. OH! I did build the enclosure but out of materials I had laying around.

What should I be looking for next? About when should I stop feeding the girls?

Thanks again for your feedback, been a big help.
