Yeah... it will work for 4 plants... you should read the grow faq LOTS of good information. When to flower?? well, plants will double or more in size when you flower.. flower a plant at 6 inches it will finish at some where around 12-18 inches. Like i said the faq is full of good information. Good luck.
