I Want to grow 2 faily large plants in there own pots, im starting from seed and not sure if i should use the clay rocks that i have or the rockwool or a combination of the 2 for the medium but the rockwool hold alot of water\nute solution and the rocks drain better and im not sure what feeding technic to use....with rockwool i normally feed it 2-3 times a day but worry about wether the rockwool meduim is still moist in the pot between feeds and the rocks i usually put it on a constant flow until the lights go off.
The next thing is my lights, A 1000w hps, 400w hps, 18w twin glow lux fluro about 2 foot long use for clones. The room is 6 by 4 by 7 foot high with 2 10inch double bladed fans. So should i use my 1000w straight up and all the way or should i start on something smaller since ass soon the seeds sprout i want to put them under the light straight away or is the 1000w too much for that even with a good distance between the light and seedlings?

Any Ideas would be much appreciated, Thanks
