Tree grow with sog

Ok, you want to use the tip, not much light comes from the tip. Very very little. You can grow something under there, but it will be stretched. You can get light meters to test for yourself, a worth while investment IMO.

My question is how much light comes from the tip of a hps bulb and will this be worth attempting?

It's less light but still enough to grow. The plant under this 1kw produced 2oz I was going to leave that grow site blank and have my fan blowing up at the bulb, instead I put the fan on top and used the grow site to see what would happen. Yes it works and it will up your gpw.

yeah t;htat would be cool but i would use all hps and vent them together

UCDWC has the right answer, I think he understands... You will definitely maximize your space and yield, even if the stuff on the table is half the size of your trees.

I've been reading more and more that the light below is a "dead zone" personally I think they'd be half decent.

Wish that picture was a little clearer as to how you have things set up ucdwc
