Snow white | Nirvana

Hello there! I'm trying to grow snow white, i bought 10 feminized snow white seeds and all of them germinated. I planted them in 2L pots they're growing now for a month or so. The plants will grow outside, in our forrest
I've got big problems with snails and deers and i'm afraid that other animals could eat my babies to, so any good advices could help me. I've heard that urine smell makes animals not to go near the plants.

fucking ants getting a free smoke off u man kill lil fuckers

I've read in other threads that you should wait till there 12 - 18 inches so they can handle a little nibble and with the dear get a bit of barb wire and make a little perimeter that's what i would do.

Any idea how to get rid of snails? I've heard that salt kills them, maybe i should use salt around the pots?
