Also, I should note... I haven't seen any fungus gnats flying around the room for a few days now. Those strips have been hanging for a few weeks so they collected quite a few gnats daily (I had blackflies too but they've been gone for almost a month now). Since they all seemed to be dying in the traps, I was hoping to let the life cycle die out. Maybe that's happened? But I'm really glad I got called on it because it's been way too long. I sprinkled ~ 1/2 tsp ground up mosquito dunk on each pot. I guess that's how it's done, IDK. More googling...
 
Maybe one of you pros can help me out...
For this run I'll be ok without a humidifier, as long as I keep my temps just a few degrees cooler. But in the future, for raising humidity, should I look into picking up a portable swamp cooler from craigslist (<$80) or getting/building a fogging unit using ultrasonic misters? I know they both work well but what is your experience here? What do you use?

HELL TO THE YES for the swamp cooler. you're in the desert, right?

just make sure it doesn't run at night.

also, swamp coolers create positive pressure so make sure it's not more CFM than your exhaust fans or smell will start to leak.

i'd recommend having it pull air from your home and then into the room rather than from a window. dry cool air in, humid even cooler air out.
 
Yes, I'm in the desert. My room is sealed tho, the unit I'm looking at is a portable in-room unit.

I understand that the swamp cooler works to cool as well as humidify (whole house is cooled by swamp cooler) so it has the potential to save me money on my electric, but I was sort of leaning toward the foggers for two reasons:

1. What happens when I need to humidify but not cool? Middle of winter and I need to humidify, I don't want to HAVE to cool as well. One device for one purpose, you know.

2. Since they work through evaporation, are swamp coolers as efficient or effective at raising humidity above 60%? I don't want to spend the money to set this up and still not have full control over my rh.

I mean I guess the rainforest analogy works... but imo you made it sound like there isn't mold in the jungle. Its everywhere. Its what kills the weak plants and feeds the stronger living stuff.

Poor wording on my part is all. Didn't mean to imply there is no mold, of course there's mold. No natural place on the planet isn't covered in spores. What I meant to imply was that inspite of the very high humidity, plants flourish like no other place on earth :tiphat:. As it relates to the op's question about high humidity, the example makes perfect sense. It's true that having a high brix level is essential to survive in that type of environment, but that's true of any environment. Weaker plants will always be naturally culled, be it by human or environmental pressure. This is getting outside of the topic at hand though :biggrin:

Just FYI, the point came across pretty clearly in the original post.

Not that I didn't learn a little bit from Bobble's response, but I think he was just trying to give you a hard time.
 
It seems like the plants are all on their way to a full recovery. There will still be some yellowing and crispiness in tomorrow's weekly photo update but it's subsiding at this point, and even the worst-affected tops are starting to pray again, albeit their color is not really what I'd like it to be.

There were two that I was really concerned about near the back, side-by-side. I just couldn't figure out why they weren't bouncing back from my a/c temp setting fuck-up earlier this week. I kept scratching my head over it, and then last night I realized (DUH!) that they were ready for a good watering. It had been an entire month since those plants asked for water, but the room finally seemed ready. So I gave the room a light watering last night, and they're looking much better this morning. I'm planning to give them a light compost tea mix tomorrow night.

Glad you understood what I meant. Bobble and myself are always giving each other a hard time :laughing:. We both have a really competitive nature about us, so nit picking makes sure we stay on top of our game :dance013:. Usually some pretty decent information exchange as a result, so it's a win win for everybody.

We're even competing to see who can grow the biggest bud with the same clone :biggrin: Link's in my sig if you want to follow along.
 
Mister_D, do you run humidity at 70%/50% day/night? Or is it 60% during the day? I remember reading a few months back that Bobble runs 70% ("70% FTW" if memory serves). Is a daily 20% swing in humidity ok? I read that anything over a 10% swing should be avoided. But it seems like a lot of the old rules and assumptions are out the window with a high temp co2 grow.

Also, just to be clear, you're talking about pulling a substantial amount of water out of the room every day at lights off, then adding roughly that same quantity of water back to the room every morning at lights on?

I've been following from the beginning. I even helped out with the rules a little (you guys looked like you were sort of floundering, thought I'd offer a little structure). I know you guys enjoy hating on each other a little -- I be lurkin brah. Your social group stands out here as one with some great role models, really glad you guys made your way over here for a minute.

I like to be around 70% during veg (lights on and off, or all day if you run light 24/7) Then 70% during the day for the first half of flower, 50-60% during lights off. For the last half of flower I like things a bit drier, ~60% during the day and 40-50% during lights off. I believe you are confused about the swing. The old rule is no more than 10 degree swing in TEMPERATURE, not humidity.

As for removing a substantial amount of water every night, yes, and you'll need a properly sized dehumidifier, or access to relatively dry intake/exhaust air. As for adding it back, as long as your plants are healthy they will do that part for you by transpiring.

A maybe not so obvious point being, in order to pull this off you either need to live in an area with high humidity, or run a sealed room.

Actually remembered you making suggestions a few minutes after I posted that :tiphat:. I don't know if you could call us role models, we're just a group of guys that happens to love growing great herb :biggrin: Though always having great herb might have influenced our desire to help others :joint: I know I'm a much better person since I gave up all the other shit, and just started smoking tons of killer weed.

Cool deal -- yeah, I know that 10 degree figure goes for temps, but I just read this morning that a wide swing in humidity can be harmful. You know how people spread bullshit on the internetz. I'm sure I seem pretty clueless at this point, especially since I haven't had an indoor grow in almost 4 years, but I've actually been growing in a variety of environments on and off for close to 10 years so those old standards are well-embedded. It's just that old standards say that 50% humidity is ok all the time, when apparently for me and this strain it really wasn't.

Is there a rule of thumb on dehumidifier sizes? Mine seems to work ok. After about an hour of lights off the humidity is down to 55 from 60 or 65 and after a few hours it stays at 50. I run a sealed room but during the day it still seems like I have trouble getting the humidity up to 60% or above, so excuse me if I take the comment about "plants will do that part for you" with a grain of salt (although you did explicitly say "if your plants are healthy" lol).

You think I can pull it off with no humidifier? No fogger, no swamp cooler? I feel like I need to spray every day at lights on to make it work out. Or do you think once the plants fully bounce back (they're really not that bad, just disconcerting) they'll transpire a little better? I'll pay close attention to the humidity levels tonight in the first two hours of lights on, and report back here for my records.

This personal help has been literally priceless to getting my environment variables hammered out. There is so much bullshit and misinformation online and I've never run 1000w's with reflectors in a bedroom like this (horizontal grow, sealed w/ full co2 supp), and never grown in an area that did not have very high humidity (think gulf south, florida climate). Who knows how long it would have been until I got on the right path to figuring out my problems -- very easily could have lost this crop and possibly would have defaulted on rent before the next crop, which would have forced me to move back east. So if I can't stop zealously thanking you, you'll understand.
 
So it looks like I have about a 2 - 3 hour lag between 60+% and 50% humidity when the lights turn on and off. In other words, when the humidifier kicks on at lights off at 10 a.m., it takes until noon or 1:00 before the humidity has settled at the right level. I would assume that this would be not-too-detrimental to plant growth, so I'll let it go from there. Right now lights off temp is about 72 - 74 and lights on temp is 81 - 83, with 1500ppm co2. I'm more than a little embarrassed to show pics tonight but I'm gonna suck it up and do it. The plants still do not look really happy the way they should but they are slowly improving. The leaves are leathery and many are still canoeing and turning under (much like N toxicity). Buds are still growing pretty quickly and look on pace with day 21 flower for a 9 week strain, so I'm trying not to sweat stressing them out [pretty hard at the beginning of week 3. I'm going to have to keep a really close eye out for hermies with all 3 strains. I'm sure I screwed myself on yield, but I'm just hoping I didn't kill the potency since it's so early in flower. I'll be satisfied as long as I get at least 3 - 4 lbs. Hell, a pound or two might keep us going just long enough.

Photo update later tonight.
 
Day 21

Update time!!


It's been sort of a rough week here, as I've documented very well. But all in all things are looking ok, and everybody's going to pull through just fine.

Panorama:

Not sure if this is the same branch anymore but it's close:

This is the worst-looking plant in the room:

...right next to the least-affected plant in the room:

Here's a lemon og (I believe) that decided to get really big for some reason. I hope I grabbed some clones from her.

MMM-MMMMM!! They smell just like blue dream! Very much like candy, honey, or vanilla! It's like God's vagina!! I hope they produce more like blue dream than OG.

I'm thinking when I hit the dispensary again in a few days I think I'm gonna try out some Candy Kush so I can have at least some sort of preview.
