What is the garage door opener for? light timing?

Sounds like you will like hydroponics.. but it will be frustrating at first.. start reading up on it now..

I have two of wally's finest digital timers that I set exactly to the same second a week ago that are now a couple minutes apart!! yea.. DIGITAL lost two minutes in a freakn week?? Thanks walmart.. I now get supplies at lowes or home depot.. bypass wally world cuz its not worth the savings when the savings dont work.

I actually got two other digital timers from a pet store (supposed to be used with automatic feeders) and over the same week they are now almost 2 seconds apart.. not quite two seconds.. but more than one second.. I can live with that I guess.. but freakn A 2 minutes deviance in 1 week?? How long would that leave my 1000 watt hps light running without a fan going after a few weeks?? enough to kill.. damn you wally!

Oh and while you are reading start gathering your supplies.. some you can use with your setup now.. like CO2.. I just scored a digital CO2 controller brand new in box of e/bay (like the kind that sell in hydro shops for $500) for $32.50!! My 1000 watt hps came from a police auction (confiscated goods.. imagine that).. I got it for $40!! Im going to put that bad boy right back to good use You can do this shit cheap just dont get in a rush.. start reading and collecting supplies now for when you switch over. Keep a watchful eye for things that you could use.
