Trying organic CO2 Boost

Bought a CO2 Boost kit (pump, hose, expensive bucket of organic compost) to see what it would do to one plant I have growing with one pepper plant in a 4 x 4ft. room under a 400 W hps temperature controlled to 70-85 degF....the kit was $178 and is supposed to last 90 days when used on my lighting timer for 12 hours/day....replacement bucket of compost is $139!!!....I am hoping it will be worth it ...and I will see $178 worth of growth increase....my plants are a few weeks into flowering (small buds on herb, and flowers all over pepper plant)....anybody else try one of these kits yet???

in see more buds the guy was talking about how one guy praised how much it increased his yeilds. other than that i dont know too much.

It increases yields, yes, but you need to have it at 1500-1600 PPM for it to really work well. You have any idea what the level of co2 is in there?

No idea of CO2 level that it is capable of....I am planning on borrowing a CO2 analyzer from work to find out....the instructions only state it is not a high enough level to harm pets, and I guess it would also depend on the tightness of the seal of my grow room to build up the CO2 level...also, the air pump just has a low/high setting switch.

Remember that it only does you good while the lights are on, you might have exhaust fans going while its on, which would be a waste. Is there any way to control the release of the CO2, like you can do with a bottle/reg./solenoid setup?

No way to control the release only low/high pump switch, but the reccommended method is to have the hose over the plant so it kind of releases downward onto the plant. I checked out the website co2boost.com and it says the ppm isn't really important with this method because the idea is to directly put the co2 towards the plant rather than bring the whole growing area co2 level up....it also had reviews from people that had used analyzers to measure the co2 produced which was anywhere from 1500 to 3000 ppm...which i guess probably depended on the way they sampled it (room or directly from end of hose). I was wondering how much a tank/regulator setup would cost though? I can probably get a solenoid valve, hose, and timer for free and i might try that method when the bucket runs out. Also, when you use the co2 method do you just turn the exhaust fan/can filter off and don't worry about the smells to maximize the co2 usage?

Ok if your just growing a couple of plants I guess that co2 booster might do the job.

I use a CO2 tank/reg/sol/timer/relay setup to keep 1600 PPM level constant while lights are on. Since my lights are separately air cooled there isn't much exhaust air to suck all the co2 out. I release the co2 right in front of my intake fan, so it gets dispersed over the whole grow area. Mine is setup to release a 5 psi stream for 10 seconds every 6 minutes, the exhaust fan stays on the whole time, but since its at the top of the box, like the intake fan is it mostly just pulls the hot air out, the co2 sits lower than the fan so it takes some time for it to suck it all out and completely remove all air. It would be a completely diff story if the exhaust fan were near the bottom.

I own a 20 pound tank, bout $120 (sweet 100% aluminum), Regulator another $120. refilling the tank every 2 months ( 1 tank lasts 1 whole grow) costs $12. Alternately I COULD just lease a 50 pounder for $7 /month and have it refilled every 5 months or so for $25 a pop. Teh 50 pounder is big and I would hate for it to fall over, not to mention having to lug a big bottle out of my house a few timers a year may cause some suspicion.
