Thanks everyone:thumbsup:

Well the 1000 watt is working out just fine. I was really worried about heat and frying the tops of the tall plants. The hood is doing an excellent job keeping it cool in there.

It is unbelievably brite in there now and light is penetrating the canopy much better, this bulb has a more blue tint so I think it will help them grow even better. The only problem is it makes it more difficult to see the tops of the plants because it is like looking at the sun. I need to were sun glasses when looking in the box now

Medjuana,

To answer your question I really don't do a flush in the common way. How I water is to alternate between plain water and nuted water therefore giving the plant time to absorb all the nutrients, therefore preventing nute and salts buildup. I also let the pot almost dry up before watering, and water until excess comes out the bottom.
