Lighting an 8 x 12 room

would 2 1000 watt lights on an 8 foot rail cover an entire 12 x 8 room no problems? would they need to be vertical lights or could they be in a hood? or would 2 1000 watts in a vertical parazontal reflector do the trick?

i recently gained an extra room to veg so im wanting to turn my grow room into just a flowering room any ideas are great im still trying to brainstorm what i want to do. i could probably get a 25k btu AC for the flowering room if needed but i was thinking with light movers i may be able to get away with not having air cooled systems and just AC and filter in the room. but i may just use the hoods with the glass taken out for now till i switch to the other reflectors if i decide on this set up.

or do they have like a crossbar where you can mount 2 lights on onerail?

if they on a moving rail i don't see why not i do have 4x 1000's in that space an without AC struggle with high temps 2x 1000 on rail would be perfect

an yes of course fit them both to the same bar

I wouldn't expect a light rail to turn your 2000 watts into 4000 watts just magically. Its about lumens per sqft, you are gonna have to take measurements with a light level meter to know whats going on. Spread the light too thin, and all you are doing is spreading your yield across the room and creating more work and costs for yourself.

A lot of guys I've talked with on the issue generally are using light rails to expand their grow space by 20-30% tops, not 100%. A lot of sad pandas out there who thought they were gonna double their yields just by adding a moving light.


Just ask yourself this question. If it truly doubled the amount of coverage, then why aren't we all using them by now, especially considering how cheap the systems are?

Light rails are used to cover the gaps/edges and spread the hot spot around a little more as to increase the premium grow space just under the bulb while giving a little more to the edges of the grow space.

i wouldnt see how a light mover is not increasing yield even if you have to do a little more work which really isnt that much in costs considering even 10% yield increase would more than pay for itself and labor in 1 grow.

Movers don't increase yield as much as they spread it around.

Ideally a 1000 watt light would cover a 4x4 foot canopy area during flower.

If you like trimming a lot more to have a very modest increase in total yield then spread light thin.
