CO₂ Regulator - Compatible with Titan Controls CO₂ Controllers and Other CO₂ Controllers, For Gardens

Regardless of what the instructions say, you must use Teflon (plumber's) tape if you do not want leaks. You also must use a wrench to tighten the bolt 1/2-1 turn past hand tight. If you properly installed the flowmeter, then the tank should not be leaking or emptying until the solenoid is plugged in and both the main valve to the tank and the smaller knob are turned to the left. The CO2 rushes fairly rapidly; keep the smaller knob no more than a turn until the flowmeter reads 2 (I don't know the units.) Get a CO2 detector!! Aim for 1400 ppm in your grow room. CO2 will enter your living areas, assuming your grow room is indoors. Turn your tank off by mid-evening or use a timer. Concentrations above 2000 ppm will be noticeable to your brain, and your plants won't like it either. Lethal CO2 potentially at 5000 ppm. Get a CO2 detector!! Unless your 20 lb. tank is near empty, you should no way need a flowmeter reading of more than 5, even if you are venting to outdoors. There are lots of plastic components. Only grab ahold of the brass parts, or you'll probably break something.

A bit expensive but it does exactly what I need it to do. Set it once and leave it.

High quality product. Works great and nice bass fixtures. Seems to read a bit low for the actual amount of CO2 in the can, but it could be the temperature or something else.

Works as it should high quality

After buying a cheap manetee regulator and returning it 3 times and wasteing 3 bottles of co2 I learned my lesson and bought the titan. It’s been 6 months and no issues and very easily adjusted unlike others.

Nice unit. Wish my gas lasted longer. This is not an issue with the regulator... It's just what my environment needs. Gas companies around here are trying to make a living off of my hobby. I've had to revert to co2 bags to keep things going within budget.

Dont buy. Never worked from day one. From what I have researched Im definitely not the only one to have issues right out of the box. Could adjust flow rate with the wheel but the flow gauge with bead just sat at 0 no matter how high or low I turned the knob. Could see the changes on my controller so knew it was increasing/decreasing the co2 flow rate but couldnt determine what the flow rate was at since the gauge didnt work. You buy these things so you dont have to guess. So saw a review with someone who suggested the Vivo sun. He had the exact same issue with his titan and he was also a longtime titan customer. Let me tell you it has worked flawlessly since the day I hooked it up. Same product better quality half the price. Have bought tons of titan control products over the yrs from timers to controllers and never once had an issue. Unfortunately this was the first thing I have bought from them that let me down. Hope this isnt an indication on the direction this company is moving in. Just my 2 cents.....Get em

Easy to install, easy to understand directions.. Be sure to carry decimal points when calculating volume, performs consistently so far - Thanks !!

i bought 4 of these regulators and use them with 4 Saturn 6 controllers. After close to a year 3 of them are working flawlessly and one developed a small leak in the auto shut off. I contacted the warranty dept (Hawthorne) and got an immediate response. To my surprise they replaced the entire unit and they covered the shipping costs! I cant say enough about the outstanding customer service I have received from Hawthorne on behalf of Titan Controls.

Great system

Set this up on a 8 hour cycle for my planted tank. Can adjust down to well under 1 bpm if desired. It is a little touchy to set that low but once set it stays solid. Loved it in the grow tent and love it for the planted tank!

Great product

Very easy to use.. solid product.. makes administration of Co2 very easy...
