it's possible. even possible to get 1.4gpw. you would need to be a very experienced grower with the right strain and your nutes dialed in. plus you would need the proper environment and space layout. anything aroun .75+gpw and you are doing just fine.

2gpw is possible but you would probably need to go with a vertical stadium or colisseum grow to take full advantage of your bulb. the only 2gpw+ grows i have ever seen were done using these methods.

I'm assuming since you are asking this question that you don't have much growing experience. With that in mind, you've got to know that there are so many things that can affect a grow. You could have insect problems. You could have equipment malfunction, or a hundred other things. Grower error is always possible. Growing weed is like any other kind of "farming". If everything goes according to plan you could have a bumper crop, but with so many variables yield is impossible to predict accurately. If you concentrate on quality, yield will take care of itself. Good luck!

wow that last one was a very good way to put it. true do not have many grows under my belt only about 8 and only my 3rd doing hydro. i was the most curious about my clones yeild. i never rooted them before 12/12 always straight in when it was cut. this clone is 14 in tall and the leaves are so crowded with many sites im excited.tn2.jpg

If they are 15 inches when you switch the light to 12/12 you will have a small harvest.
I'm guessing 15-20 grams dried/cured per. that's optimistic.

no way bigsteve i have to disagree with you on that one.. im thinking two oz each but we shall see. im a lil new but got a mean lil setup

I disagree with Big Steve.
I vegg my ladies to 15" to 17 " , and I harvest about 15 ozs from six ladies every harvest.

ya brotherman you tell em. that would make me stop tryin to grow tomatoes.

also 600 watt hps has higher lumens per watt than all others so you get more bang per watt also more points of light but its cheaper to buy one 1000 watt light than two 600's you will yield more with 3 600's than two 1,000's and use less power and a lot of growers will go hps-mh-hps for flower rooms
