CO2 recommendations needed

I'm looking to make the move to add co2 to my flower room. I'm reading tutorials and watching videos, but i don't really have a clue on a good system to buy... so just looking for recommendations and feedback. Would prefer something that would have everything I need in one kit.

Grow room is around 10' x 18', but only around 10'x10' is used.

* Needs to be a tank system as i live in a hot area and i don't need any extra heat sources.
* Prefer a system with a ppm meter/controller to keep it at specified ppm

Thanks for the feedback. Smartasses/trolls need not respond.

i can understand the reasoning of heat for wanting a bottle, but there are so many more benefits with a generator. you could get a minigen or its big sister, both are water cooled and minigen can be run with or without watercooling. the heat output is really not that bad and in a good sealed room they dont run that much, about 15-20mins to start and a min or two to keep room even. in a room your size you would be going through a lot of bottles, even 50#'ers, which is not near as easy to get as propane and much more of a red flag. and then cost of bottles will be much more in the long run, it cost me less than $7 per month in propane and a 30# tank last over 3 months.

Good points superstoner1... and probably the next major purchase after the co2 is gonna be a portable a/c unit for the grow room anyway shit took a hit of cheesequake and now i can't think...

anyway, maybe i will consider a generator as an option... i know that they are cheaper on a monthly basis than tanks. do you still have a controller that plugs in just like the tank that measures ppm and turns it off/on as needed? only having to change the tank once every 3 months would also be good -- how much did your unit cost to set up?

can anyone back up that a good generator won't add a large amount of heat to a poorly vented room?

I was just thinking about posting the same question, I have the same problem . . . .Im not sure if I want to go generator or tank, and I dont know how the generator will be regulated. . . . . actually I do know about the CAP and Sentinel environmental controllers but your looking at a big ticket for the generator and controller all at once.

Also senseimilla isn't poor ventilation what you want when you run co2, "air sealed" or are you talking about like ventilation as far as air movement "fans"

Yeah poor ventilation is the main reason I'm looking at adding co2 (along with wanting to get the most out of the plant in terms of growth/yield). Enclosed room, no windows, one a/c vent (coldest room in the house when a/c runs -- unfortunately also the hottest as I found out last week when I turned the heat on and forgot to open the door and fried a lot of leaves in the flower room )

any co2 monitor/controller will work with regulator or generator, it is basically a relay kicking power on and off as needed. i have a minigen and a cap ppm 3. very easy and very reliable. you can get propane anywhere at any time on day. and please do some reading on ac before you think about a portable. i wouldnt tell the biggest asshole on here to buy a portable. they are by far the most inefficient can also be a heat source, a big one.

What would you suggest then superstoner for helping control temps in a room that has no windows, needs to stay shut, and one a/c vent that will only do the job if the a/c runs almost all day to keep the room cool? Not very efficient to run a whole house a/c either Although if I drop the HPS and go back to all LED, the heat situation should be a lot more limited.

the only option i would consider is a mini split ac. it is a different game altogether using a mini. no odor escaping, no lost efficiency. these things were made for indoor growers.

i'll have to look that up i've never heard of it... the main issue with ventilation is this is a rental house so i can't make modifications to the structure... will that be an issue with mini split ac??

Consider a cheap homemade CO2 generator. All you need is a one gallon jug, sugar, yeast and hot water.
I mix 2 tablespoons of yeast with 2 cups of sugar and dump into a gallon jug. Fill up halfway with hot water
and gently swirl the jug. Hang the jug up high on the wall as CO2 is heavier than air. You want the gas to
circulate over your plants until gravity kicks in.

Good luck, BigSteve.

running a mini split requires a 2 or 3 inch hole be put in an outside wall, as the unit is in 2 parts; 1. an indoor air handler and 2. an outdoor compressor. the outdoor unit will need to be secured to a cement pad or cinder blocks or some type of strong level structure. coolant lines and electric wires pass through the wall and connect the 2 parts. Most models require a dedicated 240v breaker. this is the absolute least invasive way to cool a room with no windows or vents. you cannot beat physics: if you want to remove heat, it needs to go somewhere.

you could do it this halfassed way which won't do nothing for you, OR, you can stay on the right track and do it right. Without a consistent ppm.c02 is pointless.
sunlightsupply makes a preset monitor with a built in photocell, it is the best deal for a monitor right now. Unless your a big spender and want to change the ppm settings with an adjustable monitor.listen to these guys on the a/c, they have a clue.
