Alright a few quick questions: First, I have outdoor plants that are in holes filled with FFOF soil that I started late (but they're auto-flowering so they'll be fine) and they're estimated to grow to 120cm, therefore, I'm wondering on average how much water should I be giving to each plant per week? I'm thinking 1-2 gallons? Lastly, if I take tap water and let it sit for 24 hours then boil it, will that be good enough water for the plants?
