Timers ,Co2 and exaust fan sync?

[J DOG 6000]

I found this and wondered if you guys would approve of this method or is there a better way?If so please help me!

Two timers synced can be used, but the only ones cheaply available are the 30 min interval, 48 trips per 24 hours. So I could have a fan run 30 mins on, then 30 mins off. I could also sync it to the light so that I don't vent when the lamp is off. I can sync this to an identical timer that will turn on CO2 during the time that the fan is not on, and vise versa. It would be difficult to sync them closer that 5-10 mins, but at least there would be a possible inexpensive solution. $20 for two of these timers. :confused:

I have a timer (I think you e-mailed me) that has a cut off switch so when the lights go out on my air cooled hood the exhaust shuts off as well. You can click the grow lights link under my signature to see the new one i have for sale. (same as I desribed above.)

You can run a whole room with just timers and math. I did for years before I could afford controllers. It takes years to build up equipment but you need to use it while you are buying, saving and building up your equipment list.

This timer makes it easy

Thanks Zandor I like that timer...I think I might get that kind.I might just sync up a few of the same braND for this first indoor grow and buy an expensive one that hooks up to my Mac after this next harvest. :stoned:
