Growroom Electronics! Need some help! Cycle Timer, CO2 Monitor... ???

I am searching for a device which will handle a continuous timed cycle, 1 minute on, 5 minutes off. It will need to be able to supply power to five water pumps total. Three for my aeroponic flowering systems, one for my cloner, one for my aero veg unit.

I am also looking for a CO2 controller/monitor to keep a constant 1500ppm in my flowering room.

I know some devices out there may actually handle both of these tasks.... Any suggestions?

I'm trying to stay within a reasonable budget and I'd like to stay within $300-$400 if possible, perhaps a bit more depending on the item.

any suggestions\ideas feel free to comment.

For that amount of money, you're gonna have a tough time. If you are willing to do the calculations regarding flow/ppm for your cubic footage Co2-wise, then you can probably manage it with just two intermittent timers. If you want something that's going to be able to actually measure Co2ppm and adjust it automatically, you're going to have a tough time. Green Air Products make some damn good equipment. Try them.

I may actually bite the bullet and dish out the $700 or so for the CAP XGC-1e Xtreme Greenhouse Controller. I spoke with a few people running similar setups to mine and this pretty much handles everything I require. Its over double what I was looking to spend but hopefully with such an investment I wont have to bother with any "addons" down the road, this seems to do it all. I'm still uncertain, blowing that kinda cash on a single peice of equipment has me a bit shook. I think I'll so a bit more research before deciding...

I bought the greenhouse xtreme.. I went to discount hydroponics and the guy there was kinda pushy on taking the refurbished one (the only one they had) but it was a couple hundred cheaper.. so I went for it.. when I unboxed it, it started making a rattling noise as I moved it around, like it was a nut or something.. as I moved it the noise eventually stopped, but I am still concerned.. all in all I feel like this unit is very cheaply made and I really wish I would of put more thought and went for the sentinel. I went for the greenhouse X because I saw Stinkbud was using it... and he has some STINKy buds... haha
