Def try to get a good soil. Most backyard soil is full of rocks and drains horribly. Trust me I tried my first time. And at this stage of its life it dont have the roots to drink up as much as you're giving it . let it dry out a bit before watering. A misting every now and then would work at this point. And as far as pots. I got from a little seedling cup and once that fills out with roots I transplant to a 1-3 gallon. Then a 5-7 gallon. And this run I am finishing in a 15 gallon and a 20-25 gallon pot. But thats just me.some Ppl on here can grow in a solo cup so its all preference and what not.
