Hey I got a regulator and tank, my question is should I cut off the tank during flush or let it run at a decreased strength? I used cO2 a long while ago and I ran it to the end not knowing that may not be a good idea. The buds were huge but really bad no tricromes on them or flavor. It didn't matter much it was just a small grow but now I'm doing it medical so I just want to make sure. Thank u. Also for reasons I don't want to go into right now I have no intake it is just ambient air in house I'm using. I plan on changing that but I can't do it properly yet so I'm holding off. I have slight concern about the room I'm using is right next to the room I sleep in. I exhaust in the hallway. Should I be concerned with ppm levels in the house? There is a basement and it is on the first floor.( I'd use the basement but it's ceilings are too low.

My advice is only run the CO2 during the hottest 4-8 hours in the middle of your light cycle, it will reduce costs and give them the CO2 when they need it. The other key is getting good air exchange at night, if you can, i'm sure you already know this, but try to drop your temps during the last two weeks so you create a 20 degree F gap in high's and lows 60-80F for example. The wide swing stresses the plant and causing it to want to produce more resin. This is when a good shot of kelp and molasses go a long way during the last two weeks to help drive up the brix levels in the plant helping it adapt to the stress it is undergoing.

if you are concerned about PPM levels buy a carbon monoxide detector, but no, the only way you'd be in trouble if the whole tank dumped all at once and you were standing in a confined space. That is the only danger, confined spaces with little to no air exchange. Your basement will have the highest levels of C02 as it is a heavy gas.

Heyyy truck, thatsfunny I was thinking of you when I posted this. Yeah I did know those things. Something's I know more about than others...I've heard friends use only molasses during flush but never looked into why. I understand brix mostly or at least some parts-so brix must be important during flush time as well?

[deadhead77]

Will carbon monoxide pick up cO2 ?i really wish I could open a window for more air exchange but right now that's just not possible for security reasons. Anyone have a blueprint for how to make an intake secure with window that is in the open. I've had about 5 grow setups in different locations indoors and haven't had as much trouble concealing an intake/exhaust

From what i can understand Brix is a measurement of carbs/sugars in the plant. That is a representation of the plant's immune system and its ability to adapt to stress/defend itself. Wine people get sweeter and more aromatic grapes when the brix count is high, and they benefit from the cool weather too. also is why i guess using kelp and mollases early on in the flower cycle and grow cycles is to help keep the plant short and bushy, something to do with the plant being full of carbs and not needing to stretch out for energy from photosynthesis, but i'm a little out of my league in going into details, this is just my rough estimation from reading and little bits of experience. Which is why I also always include molasses and kelp anytime i brew a tea with alfalfa, as alfalfa tends to make things a bit leggy and finish later, and i guess the carbs/sugars from kelp and molasses balance out any negative effect of the alfalfa and vise versa. I experiment with different ratios in my teas depending on timing. But one of the best resin producing bottle products i used put its claim behind triacontanol.

From what i can tell about Carbon Monoxide Detectors, it depends on the type i guess, some only detect CO as some will detect both. Mostly from what i read, Carbon monoxide detectors are only going to detect Carbon Monoxide. CO is deadly or harmful effects starting at 50ppm where CO2 is starting at 5000ppm, ie you will begin to feel the effects quickly getting dizzy, sleepy, and or nauseous. If anything save up for a good Co2 monitor as well that you can set to limits on if you are worried you might be over doing it.

Unless you are using chemical fertilizers a flush is not necessary growing in soil.I have never heard of co2 levels even come close to the 5000 PPM danger level but there are many things I have never heard of lol.I don't use chem ferts and never flush and have never experienced a problem with taste or burning.The first year or so I flushed and all I experienced was yellowing of the leaves.

Big ups truck...coming through with some solid info. Great job my friend and thank you. How's things looking out where you are? Good I hope

Yeah I hear ya I absolutely flushed when I used Chem ferts and I definitely know peeps who do not flush with organic but honestly..I still do...maybe it's habit maybe just security but yeah I still do. Much shorter of a flush time though about 5 days and last 2 days no water no light
