yield per watt

So far the only side by side test I've seen was done by Migro. They claim the average yield of an HPS is 0.5 grams per watt and 1.0 grams per watt for a quantum board (Samsung LM301B). Do you agree with these numbers and where would you position a standard LED light?

What would you guys say is the most important part of growing that determines yield. Speaking both quantity and quality. I've been told that the amount you yield can vary between 1 gram for every 0.5-1 watt of energy used in lighting, determining in skill, and as far as quality goes, that's...

Honestly, I know I need a 1800w of light for 32sqft. That is optimal. But how bad is it to veg and flower with a 1000w in an 8x4 space? Anyone ever try it out. I'm guessing my yields and quality might be lower, much lower. I'm pretty bummed about that. But the person who set my grow tent up is...

Hello I'm a first time Grower, Poster, and straight up noob. I'm looking to get insight on how much you guys think I could grow with my setup. Here are my specifications. If prediction is hard give me a ball park estimate. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tent: 4ftx4ftx5.7ft or 91...

My set up is going to be..... - 2 Black dog 600 lights (heard there pree much the best) - 8 seeds/plants, fem cali dream (should i out more or less [info say medium height]) - 4x8x6.5 tent - 6 inch Carbon filter and 6 inch fan (?) - 2 monkey fans (do i need oscillating?) - Mainline for...

The age old question, and the most wrongly answered question all cannabis related questions among growers because it has no answer you can take to the bank and say, "Hey, I'm about to start this grow operation, I got two 1000 Watt hps lamps and twenty seeds, my grow space is .... I'm about to...
