Here is my room friend. Trust me when i tell you its a 4x4 area. Yes you can grow under 5x5 i guess. You do it though, I will not.
Look at your reflector, ffs man you are restricting the hell out your light. If you had a better reflector you would have a better yield.

Also it looks like you don't have very much ceiling height, I wouldn't run any open air reflector in that area, that's KILLING your light , at least 20% reduction in light from the airflow past the bulb + the glass.

9 foot ceilings and i won't.

Yeah most of the larger scale operations I have seen are all 15+ foot ceilings. The DE bulbs are PERFECT for high ceilings , no air running across them or glass to block their light, they give you 100% full blast power all the time.

Seems the ac/de scored best, it being air cooled and all seems it scored better than open reflector .

Doesn't seem right, they probably just trying to sell those cause they cost more or something. Air cooled reduces light output its a known fact. Could have been tested with glass opened and no air being blown across.

Dunno why they would rig a comparison since they seem to sell everything compared.

Not to make this about DE anymore than we've made it but that particular hood doesn't actually cool the lamp.

I was recently in a med grow facility. If by PERFECT you mean weak ass small buds that are half the size they should be, then sure, DE are perfect for high ceilings. IMO, grow facilities put lighting way too high. I understand the idea, I understand the commercialism, but it could be so much more efficient with a little bit of technology.

wow, I joined RIU 6 years ago when I was just getting into growing, and LEDs, and this thread looks like it came right out of that era, cant believe we are still fighting over which system is better. They have pros and cons, none are better than the other yet just depends on your situation. Most people that are still laughing at LEDs are probably jealous because they can't afford them. The shit I grow with LEDs is always top notch bag appeal, potency, flavorful and smooth. I recently got my best yield ever out of 1 plant in a 7 gallons pot, half a pound. That was under COBs.

4 ft plant, 3 ft clearance for light... makes 15 foot ceilings kinda silly
and how about you show us some average numbers for that standard 1000w in a 5x5 footprint and then you tell me again its all good to flower

4 foot plant is really small, that's like 3 foot from the base of the container, that would be a tiny yield.
