It's a little late to start building a quality hydroponic system when you've got plants that are almost ready to put into one. You may want to put these plants into a dirt system while you gather the parts for and build a quality hydro system. If you'd rather go Hydro, you could go with a bubbler system for the least amount of money. You'll still have to order nutrients if you don't have a hydroponic store near you.
Let us know more about your situation so we can help you.
What size of grow area do you have?
Have you bought lights yet?
