for the first two weeks i had 4 plants on one flouresant light. Seemed like they got big too quick and started to fall over. thats when i used pipe cleaners and bent them to a circle just below the top leaves. since then i have had a 400w MH for the last 3 days and already look much better. should my plants be fine now that i have an HID system?
No one can tell you from here if your plants will be fine. I can tell you that you have now given them appropriate lighting. Your plants did not get "big" under the fluoro, they were stretching to get to the light and fell over from literally stretching too thin.
