  4. Excellent Controller Review by Bruce

    This product is excellent in its ability to control temperature, humidity as well as your CO2 equipment. I'm using mine in a small grow tent 2.5 X 2.5 X 5.5. The control of CO2 is a bit tricky to adjust and is important that the flow meter on your regulator be adjusted down to almost closed. Even though the flow is not registered on the flow valve I got it adjusted to maintain a failry close control of between 1200 to 1600 ppm. It would be much easier to control in a larger environment so this is no fault of the controller.

    I also like this control because I can use my in line fan to maintain temperature and humidity in adition to controlling a heater during the night photo period when needed. This is an excellent controller due to the fact you can leave it outside of your grow room/tent and still have the remote sensor control your night settings with the built in photo eye in the sensor. My other Sentinel controller required you to install it in the same grow space in order to utiize its built in photo sensor. Everything is incorporated in the CHHC-4 for total remote control of your grow system making it very convenient.

    As far as customer support from the manufacturer, I'm pretty disappointed with their response on their web page. I filed a support ticket for my HID-2 light controller and haven't received a reply since May 26, 2012 and still waiting. Their web site is really outdated and indicates it's being updated since July of last year. How long does it take? I noticed they also blocked customers from making comments on their products as well. They need to get the ball rolling. I dinged the product by 1 star because of customer service issues that need to be addressed and improved.

    As far as The Hydro Source, you won't find a better company to deal with and get the best prices with free shipping to boot. I'm very pleased with this company and give them a 5 star rating. (Posted on 6/18/12)

  5. The way to go! Review by Jake

    First off I would like to say, you will NOT find a better cost on this unit ANYWHERE ELSE!!!
    I hunted for months for a cheaper cost, and if you factor in shipping costs, The Hydro Source has the best deal because of the FREE shipping...
    So don't wait on this unit, pull the trigger, and take advantage of the free ship!

    As far as the rating...
    Outside of the fact that Sentinel released a top of the line unit which has a DB9 interface but they released this unit without software!!
    Cannot say when, and no one knows when the software will be released...

    Other than that, TOP OF THE LINE in Total Environmental Control and I give this unit 4 Stars, only because of the software con. (Posted on 5/24/12)
