Hey Spliff. I did use a Pro-200-PAR on that run and yes it will flower. For a small 3 x 3 with 1 or 2 plants keeping it around 30-40" it's ideal. Give it a try if you have a spot where you could run it through a full grow. I think many who are into trying low wattage LED panels for these smaller grows will be interested to see the results and the area of coverage from a single 200.
On another note; I'll be posting pics up as this grow develops. This is a 20 x 25 room within a licensed dispensary here in So Cal that is 215/420 compliant, under the 99 plant limit and not too far from where I live. In meeting them I found them to be not only great guys but experienced growers who love the 420's for their clinics quality med's.
Day 3 Flower Update: The beautiful girls are already pistiling hard after just turning them over on Monday

This following picture shows the one area they were short a 420 so they ran a single 8 lamp T5 VHO. You can see the T5 plants are shorter, show more internodal stretch and the canopy is uneven. Comparing the stalks between the T5 and the 420's you can also see some of the T5 plants leaning over from an earlier foliar spray that under the 420's all of the plants are self supporting and there is no lean. Should have used T5 aquarium lamps I guess. Next update will show all 420's and this area should catch up.
