yeah i was thinking to add another 85W this will do fine i guess no? and also i want to ask on how to keep my plant short and bushy the light is like 4 cms far from the top
Keeping the light close will keep it short. Keep in mind CFL's have a very short penetration rate, so 1 or 2, and your still going to need something for the lower half.
i have found a 35w fleuro light comes as a circle i will use it to light the down side and the 85W will be on top what if i cut their leifs
