Thanks for ur help

I dont know about the other stuff but dont bye a hanna ph pen off ebay or at a shop they suck

Depends on how your growing,

most things on ebay wont be the best quality your best of going to your local horticultural store. they will tell u everything you need to know

So basicaly the Hanna ph tester off ebay suck???

You can pick up a $6 temp/humidity guage from walmart in their home improvement area along with a timer for your lights, a brinks timer is like $7 - home depot and lowes carry $10 Ph testers for soil and another model for $12 or so that is a ph meter/watering meter/light meter rolled into one. Rooh is so right, take a trip to the local garden center. Good advice and decent prices, without the shipping costs!
