I am working on a new grow room. It's roughly 125.67 cubic feet. How many lumens or watts do you sugges I use If my calculations are correct I should need around 150,000 to 200,000 lumens?

You estimate based on square footage. Floor measurements are . . . .? Remember sativas require much more light than indicas. But you can average 3000 watts/square foot.

3000w/per foot? That's not right. 60w/foot is close. I'm guessing type to fast or medicated. Your to good to state that

Trying to talk to my ahole boss. Trying to say 45-65 watts/square foot. 45 will do only indicas OK but I go big to grow big on air, containers and light. 1000 watts on each 5' x 5' is what I do. I have a 400 HPS (2) for each 22-gallon DWC unit I just finished.

Not good enough to work all Saturday on the holiday weekend so they call and want Monday. Medicine sucks. I ain't going in. I have clones that will buy it if not transplanted and some into my new DWC experimental hydro I built!8) Thanx, Warlock!

I knew what you ment. Just needed to point it out.
Glad you did. We were talking the cost of a single hemodialysis treatment. $3000.00 for a 4-hour treatment. 3 times a fucking week until dead or they quit. And the bitch squawks about a raise I need for new equipment? We run 29-36 a day at that rate. Or more in a pinch.

i grow in 60 feet of space and i use 400w if your room about double my size then imma say 1000w mh/hps would be sufficient

Even thow I would love to see how someone can get 31,250 watts in that area. It's not happening. So I knew it was a mistake. But if anyone wants to try post some pics. Lol I'm having fun now. Got a few drinks in me.

well my measurements aren't totally accurate but its very close more like 3.3x2.7x8 so around 71 but either way not that far off

Its a loop style green house. The l x w x h is 16'x10x 4.7 Because of the curve at the top then obviously the real value will be less. But depending on the exact shape of the inverted "U" then the l x w x h is a bad formula.

Oh and im putting 34 plant in the space. Most of the plants are
indica/ sativa autoflowers. Easy Ryder, pandora, amnesia, and cheese.

Think I have a idea of what the greenhouse looks like. Is it out side? If so just use it as a green house. Keep it warm. Autos will do fine in the short hours of light. But your going to need to lst big time if it's only 4.5 foot high.

I thought I would have to. I found the formula to measure the cubic feet of my house. After a little legends lesson. How many wattage am I looking at
