get some 5 gallon buckets
some hydroton
they sell net pots that fit perfectly over the bucket i think like 9 or ten inch.

ph/ec/ppm tester
thermometer\hygrometer
fans
gh bloom and gh micro for nutes and youll be cool for 1st time
once you see how fast they grow in water you will be amazed
after that you can upgrade
