co2 controller worth it?

[KHAN]

I was thinking about CO2, I've seen the manual valve release for £145 which seems ok, but the digital controller is another £120 on-top.

Question is can I easily do it manually or is it too much hassle? :)

I have a co2 generator, but haven't decied how to control it yet. As far as I know there are two ways. Have it shut off by PPM, or by time. The controler to use PPM is about $450. The cyclestat (for time) is about $150. I would much rather use PPM control.

Also, search tel-air ventostat, A cheap way to use PPM. I bought all the stuff for this, but I can't figure out how to put it together. It requires some wireing and stuff. There are (or were) people in this fourm who directed me to that, so I assume someone here knows how to hook it up.

its worth it if youâ??ve perfected growing with out it. If you havenâ??t then thereâ??s no point as you can grow great weed with out co2. :)

True that. I guess that's why I haven't hooked mine up yet. Higher priorities in my weed farming venture prevail at this time.

Actually, you need both a timer and ppm contols. The timer so that the co2 only operates during lights on - the ppm to, obviously, regulate your ppm for optimal conditions. There are many controls available that do both time and ppm.

I always just plugged the controller into the same power strip as one of the lights, so the controller didn't get power if the lights were'nt on

This is how I run my main exhaust system, just off the same circuit as my lights, which is on a time-clock on my main electrical panel. Anything that needs to run only during lights-on, this is the KISS method.

Dro's don't believe in KISS - the more timers and dials and settings, the better life is all around. LOL

Actually, any time I see "digital" used in reference to a controller, I hesitate to recommend cutting power to the unit since that really isn't the best way to treat a digital component.

What about this;

CO2 Kit (http://www.1-hydroponics.co.uk/c02-release-systems/c02-kit.htm)

Except the bottle is that everything you would need?

That unit uses mathematical calculation, as opposed to actual measurements, to determine your co2 needs. Accordingly, it's not going to be all that accurate.

Check out this unit. (http://www.bghydro.com/BGH/itemdesc.asp?ic=AACCPPM3&eq=&Tp=) It's about $90 less and it measures the co2 in your air, but doesn't have the valves. If you could pick up a set of valves for 50-100 quid you'd be a lot better off, controler wise, without spending too much more. You might be able to find this in the UK with the right cord ends and voltage.

Yes for about $1000.

Yes, you need to have it come on just as the lights do, and if environment permits, several times throughout the day. Of course the first on for the day is on a timer, but the others could be by temperature.
