www.discounthydro.com

i've used them several times and they ship discreetly from california. insidesun is also very good...

for other growing needs i use www.gardeners.com a lot. they have battery operated pump timers for indoor and out along with other growing needs that help when going away for up to a few weeks.
del... Reviewed by del... on . Buying lights? Anyone buy refurbished ballast online for the lighting system? You can save a lot of cash doing this. Or would I be better off going to my local grow shop and buying a brand new light system so I know it is safe? I am going to purchase a 175 watt or 250 watt hps for my new grow area soon (3 max plants). They are going to be some killer tomatoes! Rating: 5
