Ready to buy: Which CO2 controller to get?

I plan to keep my grow around 1500 ppm. I am currently running the tank on a timer. My grow is sealed with AC and dehumidifier. It is a 4x4 secret jardin tent running 1000w on a 9 site rdwc.

I am really split between a Cap PPM-3 and a Cap PPM-4.

PPM-3:
Pros: More control.
Cons: cost more

PPM-4:
Pros: Cheaper, simpler.
Cons: Simpler.


I found the PPM-4's online for 190 shipped. I also found a PPM-3 refurbished with 5 year warrant for 250 shipper.

Is it worth getting the PPM3 to get a new unit and save 60 dollars? Is the PPM4 much better? Will I notice any difference in them in use?

I am going to order it tonight or tomorrow. If anyone has any input on this, please make me feel better about my choice! Thank you.
 
I prefer the sentinel cppm-4, but that may be to much $$ for you. it has a sensor with a photocell, it reads levels at plant height and up tp 16 ft away. it shuts off when the lights go out.
 
i have been looking at those but i just use a timer and alot careful calculations(enrichment times, time to disparate i test with simple co2 tester just so i know how long co2 stay in the area, vent times to balance co2 and humidity). i plan on buying the sentinal for later use... but as long as its small scale i probably wont buy a controller. but i have been thinking about it i think the downside is that you will need a dehumidifier because the same air will be constantly recirulating

My grow is sealed. Nothing goes in or out. I have the AC and dehumidifier all set up. The reason I want a controller is because I am concerned that I am either not filling tent with CO2 often enough or too often. The simple testers would cost me 30-40 before I got it dialed in. It isn't a money issue for me, it is about return on investment. I'm going to get like 20-30 ounces on this grow. What is 200 bucks?

That controls when the CO2 is released, it doesn't control the PPM. I appreciate you looking though.

My choices are:

PPM3 for 250$ (refurbished)
http://www.horticulturesource.com/c...=ppm3&osCsid=fa521e4f1e62d25f772d7838a620415c

PPM4 for 190$

Both come with a 5 year warranty. I won't be buying them at that site, that was just the first place that popped up.
 
I have the Titan Atlas 1 co2 controller monitor with their regulator on a 50 lb bottle going thru perforated tubing that's below & around the two air cooled reflectors (600w hps). Have had zero problems with it and the bottle has barely moved off full in over 3 weeks. I set it for 1450ppm, altitude & it has an auto shut off for lights out period. Shop it, there are deals to be had.
 
The new Iponic 600 is DELISH!
For the price of 1200 and what it does... its a indoor growing DREAM!!
I'm getting on after this grow!

For just CO2 Hydro Innovations puts out a great simple CO2 Controller
