I have a grow going in soil however for my next grow Im going to be building one of those DIY 5 gal Bucket DWCs. My question is some of the ones I've seen have a tube along side the bucket some dont , I need to know the purpose of that tube before i can decide weither or not i need it. I assume its for water level purposes but i could be wrong i also have a hunch its used to feed nutrients in but hell IDK lol thats why im asking also if any of you have used DWC is there a potentcy lost vs soil Never mind taste I mainly care about Potentcy. Thanks all
