I'm going to start into tissue culturing soon, and between books I've been wondering what material I should use. I have a few Pinguiculas flowering, and thought I would start with their seed. Lately on Ebay, though, I've noticed a seller offering In vitro material such as N. Eymae, D. ordensis, H. Nutans ect. I am wondering if it would be a good idea to purchase the flasks, since they would most likely be sterile, and it would be a matter of replating to another flask and growing a callus until I have an army of plants. My only concern is that I would contaminate a flask because of my lack of experience, and have to just plant it in soil. Any input is appreciated, Thank you.
