yeah dude i know the feeling. bought a new 4x4 tent had to give the old tent back to a buddy, 1000 digital ballast, 400 digital ballast, 400 mh bulb, 1000 hps bulb, 8 inch hydrofarm fan, fan controller, new air cooled hood for the 4x4 just cuz my old one was kinda ancient and i told my buddy id hook him up with it when i got a new one and a couple other odds and ends and it all cost a little more than just ur co2 rig. lol. i want to set up a 4x8 for flower with 2 1000hps in it and i want to use my 4x4 for veg with the 400. gotta buy a 4x8 tent now and another xxl hood and im in business, so co2 may have to wait a little while. how much r the tank refills and how long do they last? it will return ur jew gold in a few months hopefully with a little hard work. lol. the 1000 stuff is for the 6x4 i already flower in. it just needed updated equipment. stuff it had in it was getting kinda old and the warranty dates were approaching and the bulb has had a few goes at it already too so it was time. lol.
also have u figured out how ur gonna dry and cure ur buds yet?
