how often do you flood the system?
 

Ron, I just found your site!!! Whoaaaa the best hydroponic website in the cyberworld!!

Can you kindly answer the following questions before I mess up my plants?

1) Im using 2 liter bottle setup to grow some kind bud. Once I put my 3" sprouts into the grow rocks, from then on how often do you flood the system? Like what's the water cycle from then to maturity? How many times per day and for how long?

2) In growing with limited height (5 1/2') with a 400 watt hps, when is it a good time to switch to buddin stage?

I water every 20 or 30 minutes in all my gardens no mater what I'm growing and whatever age of the plants. I also water 24 hours because it's convenient not because you have to.
