Testing the Bio2 CO2 producing bucket

We will just have to agree to disagree on the bucket being a good permanent solution I guess.
As to your cooling issue in the tent.
Tents are really problematic because of the thin layer of cloth the temp differtials played havoc on me I got condensation on one side or the other not so bad in summer but winter my humidity would go off the charts talkin puddles on the floor with a dehumidifier runnin 24/7. When its cold outside an warm it your tent is when it gets crazy.
The one thing that somewhat worked was I cut a hole in my tent high up built a wooden frame an mounted the window ac like it was in a window. Tou have to make sure the ac has air flow tho or it dont work, I built a box around it an had a suction fan into the attic pullin air thru it.
Also Inline fans one on top pullin one on bottom pushing. Its an up hill battle I wish you luck. I could never solve the problem of the temp difference so I just moved inside tossed thetents an saved myself a million headaches but thats not an option for everyone.
dont get me wrong either I want them buckets to work for you its just hard to believe after runnin co2 you would get much positive return for the cost in the application your talking about. But in the end its your wallet if it makes you happy an you see value then its all gravy.

What works for us can deffinitly be different. Thats whats so cool about growing. Ive used several methods, with good results. Lots of different reflectors, lamp brands. We simply have our reasons for choosing our co2 methods.

I would not choose a bio2 for my larger future project I have the gear for. I will however use it in a tent no problem, which it is designed for. For me the tent is a temporary room, so the bucket is as well. I have alot of gear waiting for a better spece. Its unlikely ill use co2 in a larger room, im really using it to get the most I can out of 5 sativas as in a small space.

At least it works. The meter shows its working and its working well. Everyone can debate this and that about it but the fact is, it is producing co2, as much or more than mmp told me, its a mix and forget for a week deal. Its a product thats working exactly the way mmp explained it to me.

This is my first time using co2. All im paing for is sugar, which at most will cost me 60-70 bucks. Not bad to get to test out a cool product like this. Mmp was even kind enough to lend me a moniter. Even if some here arent interested, I am. Its worth it to me.

even if I get a extra oz from doing this test its worth it. A zip here is like 200 bucks so I dont mind paying for sugar. Im not going to put the screws to mmp, hey I need sugar too fork it over. All im doing is taking pics of a grow I already would have done so, and taking pics of a product in use. I think the arrangement is pretty fair.

Thanks for checking it out and posting anyway stoney. Keeps this thread moving along.

Im having fun anyway. This test is one im actually enjoying

Why dont we all just wait and see if I get a killer yield with this system here, and watch the ppm pics before we tear the bio2 to pieces and heckle mmp to death?

I was just in mmps store. We had a good chat. Hes a cool guy.

I saw this shaker thing today. Wow I am totally ignorant about whats out there for bio active co2 products. Honestly im a little glad I am. If I spent cash on that...



The meter read this morning. I opened the tent a minute after lamp off time. It was pretty warm in there, but im not too concerned.

Ill post the ppm pic when I open the tent tonight:biggrin: so far im impressed at the ppm levels in my vented tent. Its even more impressive non vented, but I have chosen to vent the tent

I have chosen to change my setup again. Insted of using my ac to cool the tent ill air cool the bulb in a cool tube I have. Sad day for me but ill survive. Rather than overcomplicate the grow ill just do what most tent growers do...

I need some stuff to do it but I have an idea. Im goi.g to talk to mmp when I get a chance

glad its working for ya ..with co2 you can have a bit higher temps...air cool light should remove a bit of that heat..i ran co2 in a tent for years..bottled in summer and propane in winter....yeehaw..

I was aware of that fact. That is one of the reasons im not super concerned. Im also growing a bunch of sativas, which by nature are better adapted to deal with heat. Go sativa genetics!

Thanks for hanging around trout. Added input on the tread is always welcome.

Big thanks to explosiv for moderating my thread without killing it. Im new here and not familiar with what will cause threads to vanish, but im glad you chose to remove the disruption rather than the whole thread.
I really appreciate it

pic of ppm 20 minutes after lights off this morning when I
woke up. Just for you guys. There everyone, it slows down, thus "wasting" less.
Second pic is while lamp was on last night

Hey when you did the homebrew for co2, did you ever check ppm with a meter in the tent?

If not are you able too? I figure you would be the right guy to ask. If you own a burner and a bottle setup you either have a moniter/something that moniters, or can afford one. The simple one is fairly inexpensive

Major lighting chamge. Temps were too crazy had to start using the cooltube. Bummer.

Its setup now. Also switched the airflow. The tent no longer exhausts. Its recurculating, sucking though the can filter. I then ran the duct on the outside, then back in the intake sock on the bottom. I decided to do this to keep the co2 in. Yay now everyone can be happy the tent does not need to be vented anymore thanks to the cool tube.

Pics update tomorrow.

Also picked up a little sippy bottle of dyna grow protekt. Now im currious to try their line of food. Ive heard lots good about protekt

Lookin good! Im happy with that right now.



Cheap and simple cooltube. Now the temps are much better. Sativa + co2 + silica = good temp resistance. where im at now is alot better than what it was. Its a little higher than ideal but im not worried now.

I am satisfied I finally have everything under control.

I added 2 clones. A kali and a strawberry. all except one kali are not as branchy as expected so I have alot of empty space. If all my phenos are fairly slim ill do my next grow a little different. 3 kalis, 3 strawberry, 3 slh or whatever. I wasnt sure what phenos id get, and all could have had alot more branching so I didnt want to overplant and have to cull. I dont like to waste seed and am fine taking a slightly smaller yield getting to know my phenos on this grow. Next one ill know what im working with and how many I can fit.

So far they arent streching out of control. I am very happy about this. They got about 3 weeks veg and are on week 3 of flower and havent gone nuts yet. . Like the phenos so far, if I can get a few ozs off that skinny kali that would be great. I could fit about 20-25 of those in a square meter. That would be great smoke for a while.

My slim pheno kali mist is getting crystal already. Its the only one in the room. Not that its actually indicative of anythimg special, I do watch for standout charachteristics among my seed grown plants. So far the fact that that plant is not very branchy (the slim pheno...) is actually a trait im happy with. If I can stuff 25 of those into my square meter tent id end up with a fair crop. Not my usual way of growing but I work with the phenos I have. If I had a jungle in my tent obviously id have way less.

Sweet. Im pretty happy with that.

Trying to figure out how to lower my rh. Needs to be quiet and cheaper the better. im not worried this early plus this grow is all sativas that are fairly mould resistant. Helps im using silica as well. My tent is also recurculating pretty well so im pleased.

Yo give a quick Google ofeither just vpd or vpd:icmag.com , make sure you have every leaf moving and don't even worry about it. If there's any sativa genetics(equatorial plant- humidity hangs out at like 95 where I'm from) you will see great yields. Utilization of vpd +co2 is how some guys on here are getting either 3 pounds a light or 3 grams of watt I don't remember which. But room design and air circulation will make or break a vpd grow. So read up on that vpd. Here's the chart for reference match up your rh and temp then there's pretty never too much wind. and bam happiest plants evar

If I google vpd it will probably pop up vancouver police department. Lol dknt want any part of them, they are some mean fuckers

I did actually check it. As im new to usimg co2 this ought to be something to read about after work today.

Im not actually that worried right now. Everyones at least 70% sativa so im not worried. Also in my time of growing I have run slightly higher than normal rh without rotting anything. Ill have to look more into vpd later. Should be good stuff. Thanks DJ

Big thanks to dready jake. That information is excellent, very helpful for folks new to co2. Alot of the target market for the bio2 will likely benefit from vpd info.

Thanks so much man! It sounds like you have just the environment they want and as long as all leaves are moving you'll be golden!great meds and yields.

So if all the leaves are not moving then there would be a risk of mould ? I havent hooked up my oscillating fan yet.. Probably should have, just got lazy.

There is substantial flow in the tent, the filter sucks from the top, then exits out through duct and back in the bottom sock on the tent.

Ive always grown with fans but wanted to see if I could get away without it, wasnt sure where to hook up a wall mount fan on a grow tent.

Ya not necessarily in early veg but if leaves rest on each other and transpire moisture into each other with no movement it just chills there and molds up. Plus all the leaves moving is a good indicator for flower time that airs also moving around stems and buds making sure mold can't start. I

They have panels to bolt things to like oscillators. I hung 3 or 4 clip on fans with no clip from the ceiling. I prefer ceiling fans anyway. No area loss

Yeah tonight ill try hooking up my fan to the ceiling of the tent tonight. It dosnet have anywhere to bolt stuff to as far as I know I looked over it pretty good.

Im glad you told me aboud vpd. Humidity was 70 when I opened the tent. Normally id be concerned.
