WheelOFortune's - first turn

do you think i should hook up the extra venting, and not exhaust the tent? (connect cool tube with outside air on both sides) i would open the tent at least twice a day to freshen the air and check on them.

that would def kick the temp up 5 or 6 degrees i think too.
it might get very humid though.

would the air get stale if i do this?

they dont smell too bad yet, but this would help with odor i think too.
 
oh, and tor, taking the 5 lb in every few months? try every other week.

plus, thanks for the advice, but i have no way of running it for a period like that,
at best, for now, i could switch some timers around a get one that can do 15 minute periods.
my life would be alot easier if i could do it in a 30 minute interval.
using those two durations (15 or 30) can i properly dose my room?
if i only need 1/2 cubic foot for a 225 cubic foot room, and my flow rate is 1cfm, shooting for 2000 ppm, i should only run it for 30 seconds?
that doesn't sound right to me. i couldnt do it anyways.
 
WOF, your issues are specific to location, and working numbers around having no CO2 monitor, that cost real $. I can't help, but want to use your journal to reply TorturedSoul. Thanx for your indulgence. 15% of men are somewhat colorblind, most likely the specific tones I see using it. For you, pH meter is not "fancy". I remember RO machines, 20 cent. 20 years ago.
 
Well, if your temperatures and humidity go up, and you are pushing big lights (think you are), then you have created the conditions that MJ existed in when the ambient CO2 levels were in the 1500-2000ppm range back in the distant past. So things might actually work well.

I would have some concerns about not being able to meter your CO2 down enough with your current equipment.

If you can close off the entire room though, you might be able to do lesser frequency injections (which your timer/injector seems to be better suited for?) but larger amounts which due to the then closed recirculating nature - if I understand correctly - wouldn't go to waste by being sucked out of the area.

It would also keep the elevated CO2 levels from the rest of your home. Better safe than... dead, I'd think.

What are the dimensions of the room that the tent is in?
 
9 by 10 by 8 i would guess.
i have read opposing views, some say plants thrive to 95 degrees in high co2,
but i also have read that plants stop all extra growth above 85-90 degrees.
im not worrying about high temps this run, that will be for next time.
well see what happens tomorrow, i'll change the venting.
 
10 min. 22 sec. at 5cfm would get your entire room up to 1500ppm CO2.

At 1cfm it would take 51 min. 50 sec.

Would those times be something that your current meter/timer could manage?
 
so in that case i would think (2) 30 minute doses aught to do it.

if im not exchanging air in the tent. often.
 
If nothing else, the fans that aren't venting the light separately you could (depending on equipment and/or budget) set to be off for periods of time when you are supplementing the CO2. But if I understand your setup correctly, raising the ambient CO2 level of the room the tent is in would keep the level recirculating into your tent?

I am afraid that I can't really tell you how much of that 1500ppm CO2 the plants will consume in a given amount of time.

I guess you'd need a good CO2 meter/monitor for that lol.
 
i ducted the other side of my cool tube.

now the tent is no longer being vented.

i have my cfm set to ~1 and have 2 30 min injections. once when the lights first go on, the next 6 hours later.
 
i will update high temp, and humidity when it reaches it.
 
my tent is 80 degrees 88% humid.

and i just looked at my regulator.elenoid, and flow is in cfh not cfm. duh.

that makes more sense, so i think the two 30 min doses at 1 cfh, should be good.

is the humidity going to be a problem?
 
I would have concerns about mold. CO2 can't fix that.
 
i know, i know.

i guess i have to connect another fan and timer and vent in cycles.

this hobby is too expensive. lol.
 
well, i didnt do anything yet, my res is good, my temp is good, it got to 84. humidty was 88 at the top. . . do i really have to do something about it?
i may be fooling myself, but i think i already notice a difference with the co2!

the lr#2 is getting to be the biggest plant. by 1/2 in. now.

here are some pics:

and the temp=84/humidity=88

enjoy, you can see the green is back in the leaves.

getting alot thicker now, i think they're all gonna stop vert growth in time.
i just gotta keep the res dialed, and dial in the co2, and im cruisin.
and possibly solve the moisture problem, if it starts to show in the plants, and even if it doesn't.
 
That wheel looks to me more fun than having the Ferris Wheel stop for a long break with Peggy Sue and I on top lol.

Bet you'll get so high that you... can't even see your house from there.

I wouldn't panic immediately over the humidity. You're environmental conditions are combining to give your girls that ol' primal urge.

But as it gets later in the flowering cycle, you definitely want to drop it. Mold happens.

Maybe try dropping it as close to 0 in the last three weeks as you can get it - not only to prevent mold but also to see if it causes the plants to "seal themselves against moisture loss" by producing mad extra THC.

You could even get twisted and switch to an unshielded MH bulb during those same three weeks to bombard the girls with beaucoup UV radiation. And when you enter one in the Nug o' the Month contest, we can all take turns guessing what color the bud is - and then you can take an ice-scraper and scrape off some of the trichomes and see who guessed correctly lol.

Sorry, pills are working for once.

Actually, there is some empiracal evidence that extremely low RH and high UV radiation during the last three weeks or so will boost THC/trichome production substantially. Seems like you've got to do little things like that for the Cannabis Cup competition.

And speaking of MH, if you have a favorite strain but haven't grown it in the VG because its stretch-phase makes it incompatible, try running MH lights during the first 40% (the stretch phase) of flowering.

For some reason I think it would be really cool to see a VG turning 60RPM. Might make it hard to keep the RW moist though.
 
lol, the increased G's might make it a flat monster, and keep it away from the light, you could just slow it down for feeding, lol. lets try it!
 
about the mh, i want to get another 600, and it would prob be mh.

but i think mine will stop in time with just the 600hps.
