I just ordered seeds for this charming looking grass called "bunny tails". I got a packet of 9 seeds from Ebay (since I'd had good luck with ebay sellers' seeds in the past) but unfortunately, the instructions aren't what I'm used to. (enclosing a photo of the envelope I received)

Do I really need to go through all this noise with a milk jug and plastic bag? Or can I start these indoors in a Jiffy greenhouse (as I've been doing with all of my other seeds)? How deep should they be planted? I'm confused on the 1"15" part of the instructions.

Thank you for any help you can provide! :)
