At the moment I am running the Pro-Grow 260 which sucks in about 190w, and I also have 4 x 20w CFL in there for heating purposes.

So that gives me 270w. I only kept 2 plants so I could have done much better if I managed the canopy better and had 4 plants maybe.

Keeping the plants short and not growing over each other is important. I learned this the hard way !

I couldn't hazard a guess right now as to what the final weight will be. I know I will be happy anyway. I have my axe sharpened and 6 large storage jars at the ready for curing.

On average 70% of the weight of the freshly harvested weed will be lost through water. So 100 grams wet is really 30 grams dry... (not that I don't think you can do the math )

It won't be too long now until I hack these babies down ! Yummy I think I can see a few ounces dry so far I hope. I can't wait to take the harvest pictures

So at 270w your friend would get 270grams dry... I don't think I will get that but I did have some teething problems during my first grow with LED and in a tent.

I'm happy I could have been of some help to you I'll be keeping a close eye on your grow

My progressing journal with LED grow lights LED grow light was invented four years ago,over the several years,it has been being used by minority gardeners.But there are still lots of users suspicious about the LED grow lights, I am one of those ones LOL! But since my tent was only 4x4x6 ft, and my old HPS and MH lights always emitted too much heat, initially I had a 220CFM fan on the exhaust to a carbon scrubber, but the temps were still too high. Of course, I didn't realize that I got a booster fan! So I got a 440CFM 6", which is much Rating: 5
