a little help

Ok, so far I have a small hydroponic set ( which looks like a small tuberware container with holes in the top for 8 plants, air pump, and rock wool) and am waiting on my 250w hid system which includes mh and hps...can anyone tell me what other items ill need or cheap substitutes ? I hate having to run to the store all the time but am not sure what all is necessary for my project...thanks!!! O yea I'm using seeds as of now but plan to use clones also

If your doing hydro, you want a PH meter and a ppm meter.

you will need a fan whose sole job is to blow gently on the girls to keep the air moving. Two timers. One for the lights . One for the pump cycle.
A good air stone.

You'll need to do some research on RIU, there's a lot to growing. Sounds like you will have the basics but you'll learn what you need as you grow, or research.

Yea Oct done quite a bit of research but it seems to like to some people some things are absolutly necessary but to others they're not needed at all...I'm sure as I gain more experience ill learn a lot but I'm a little confused atm
