water every 3 days, like above, when it gets dry ontop, truth is there is no one way, use common sense, be consistent and use moderation, there is no need to go to extremes, besides once plants get over 3 feet its hard to kill them.
Growing WEEDS is really easy, you dont want to baby them, you want to make them tough,,,get the best soil Ocean forest,,, and good lights and water them, and leave em alone!!! Most problems come in is when people tamper around with things too much, and end up complicating things. Take a botany class!
