Really Lip...a 2 gallon container can hold 2 gallons of water in the soil?

Flush for 2 weeks. Your friend is right.
the plant will look pretty dead by the time it's done and ripe.
A magnifing lens with a light on it. Helps . You need to look in the grow FAQS.
Water with alot of water like Lip said. But not 6 gallans. Thats way too much. Just use about double what you usually water with.
