Hi. I'm the guy who asked about the cannabis plant. I am thinking of making an ebb/flow system for my plants, for the simple reason that it would take up less veticle space than using the 2 litre system. I am gonna be growing in 4ft tall grow box, and the reservoir and grow tray alone are going to take up about 20 inches, so I need to spare as much room as I can. I am going to be using sterilized lava rocks in the grow tray which will hold six plants. I have 3 questions.
1. Will the 2 inch pvc hose connector that I am using to both fill and drain the system get clogged up by the lava rocks, and prevent the system from draining? If so, how can I prevent this?
2. How often should I flood the system? I will be on a 24 hr. lighting schedule for veg. growth.
3. I want to try to use Miracle grow as my
nutrient. What would be the best kind to use for growing buds?
I know this is a lot of questions, but I want to make sure that I get everything right the first time. Thank you for your time.
