Your call but I personally like that SNL x NH.....I think you are MUCH better off starting in some sort of starter plug but I'm not familiar with that particular brand. Either way, clone or seed.....the plug will make things much easier.

Treat it like a soil thing and water like you would normally....that's what I do with my rapid rooters.

I definitely DONT recommend taking something out of soil and putting it in hydro if that's what you are thinking. Just be problems waiting to happen imo.

PS.....Sounds exactly like what happened to my clones. I soaked them.

Also....be ready with your setup running and going when she sprouts so you can move her right away.
