I'm looking for a dual timer that can turn on a CO2 and turn off a fan. I wonder if anyone can recommend one. I was looking at the Sunleaves SunDial Dual Timer, but not sure if it can do it Sunleaves SunDial Dual Timer

you need a climate controller. something with a photo sensor so that it can keep the co2 off during night cycle. i was looking at one of these a while back when i was thinking about upgrading the co2 system i have. i didnt get it, but if i do, its most likely what i would get.

I use Control Wizard for my brain to run my co2 and fans, they run right around a bill I think. Only turns the co2 on during daylight hours, and when the fans come on, turns off the co2. Have a couple of them, and been using them for years now with great luck.

Happy Co2ing

i bought 2 shit timers that didnt work properly, my brother (electrician) suggested that i run half the current on one timer and half on the other.

hehe it works fine, although they seem to have a 18h day (says 24h on them)

but that was cool, i needed stash quicker (was going abroad)

so how about using 2 timers (good ones ) and synchronizing them?

or make the shitty timer trip an AC relay. that should handle your load.

Those control modules are nice, but a bit out of my price range.

I only put the CO2 on 4 times a day for 15 mins. I was going to use 2 independent timers, and just have the CO2 come on when the exhaust turns off. My only concern is keeping the 2 syncronized. Maybe some sort of relay switch that would turn off the blower then the solenoid on the co2 is turned on. Maybe something like a cut-off relay switch type deal
but not sure where to start on components. Any help? Maybe I should ask in an electrical website.

i made one with this time clock

59-581-1015 is what you want (mfg # TA-4079) ...

what you want to look for on them is the SPDT That stands for Single Pole Double Throw

one load is off while the other is on

i was going to use the one i made for when i get another 600w hps ... two rooms, one is off while the other is on so there is just one constant 600w load
