Help, They are Turning off the Power for 9 Hours, No Ventilation Possible

[endogarden]

So the power has to go down for 9 hours so they can fix some crap nearby. This starts in an hour for me. Lights go off in like 5 minutes, but ventilation is needed during dark time, and so are my 2 dehumidifiers....wtf should I do

Temperature and humidity will definitely rise very high, like they did the last time the power was out.

I am on day 6 of week 8, and they are very close to finished. My 32 veggers will miss the first 4 hours of their 18 hour light time, but I think they'll be okay. Although they will also get super hot and humid in their small closet.

Does anyone have an opinion on whether, PM, bud rot, or other mold can develop during a 9 hour time period? Am I really going to have to go rent a generator for this bullshit?

Last time I had to use a piece of cardboard as a hand powered fan, leave the grow room door open, and just viciously fan the humid air out, which doesn't do much let me tell you. And I didn't have a veg closet in there at the time either. If anyone has any non electrical ideas for removing heat and humidity from a room please let me know.

go get yourself a generator man... that's about your only bet.


good luck either way.


peace.

Thanks for the input, I'm thinking of trying to use cat litter crystals, they remove moisture from cat crap and piss on contact, so I'm not sure if they will absorb humidity from the air, although I think they may be the same crystals that they use in those low end EVA-Dry "dehumidifiers"

9 hours should not be long enough for mold or mildew to set in,unless it has started already ..then it can get worse..but if things are looking good and healthy..9 hours is nothing to worry about..a generator will run ya 350$ if you have it to spend get one..always good to have

 

[Corso312]

and that is a cheap generator, nice ones run 500-1500

9 hours should be ok bro

Thanks for the input, I do not have any mold or mildew problems, just a few fungus gnats roaming around. I definitely cannot drop for a adequate generator any time soon, I was thinking of renting one for a few hours from an equipment rental place if things got really bad.

 

[Corso312]

probably run ya 75$ to rent for a day..plus 2 gallons of gas comes out to around 85$...borrow one if ya can..but not necessary if it is for only 9 hours

Let's hope so. Well since this is an issue that could affect us all at one time or another, we should brainstorm some ideas for a Power Outage Grow Room Survival Kit.

Edit: So....it's been 34 mintues past the outage time....nothing yet.....maybe they changed plans with short notice and it's not happening anymore? Please...

 

[tinyTURTLE]

you are close enough to done that mold isn't gonna have a chance to get a foothold.

Shit man if my power goes out I'm fucked, I do hydro and if my pumps are out for more than 2 hours my whole table dies if I'm not home costing me a lot..

Nine hours should be good.

What is the outside temperature? It cannot go any higher than that.

Humidity will be the issue. If they are in dirt, I hope you didn't water for a few days. Might help a tiny bit. Plants give off water in the dark period. Good luck for the time.

Remember, it is only nine hours.

Usually, utility companies are quicker than their estimate. Everyone is pissed off because power is down. They like to estimate on the long end so they don't get people more pissed off by turning lights on late.

Okay so, the power just came back, only an hour after they said it would. It went out like 40 minutes past the time scheduled. Lights come on in 45 minutes. It was 69F and 79%RH in there, now it's rapidly dropping, humidity is at 66%RH and will settle at 40%RH in a while after the 2 dehumidifiers get rolling.

Thank you to everyone for your concern and input. I hope this experience will help shed some light on a problem we all could face but probably haven't prepared for. What if it went down for 3 or 4 days without warning? I think it's time to buy a small-to medium generator, some battery powered fans, and a huge bag of moisture control crystals.

Please add any other ideas about making a Power Outage Grow Survival Kit.

if you have enough money for a couple generators, may as well just get a natural gas backup generator wired to your panel with an automatic transfer switch.

Well I don't have natural gas, I have propane, which is expensive as fuck, not as much as gasoline though I think (even though LP's a byproduct). But that would be ideal.

Well upon checking the high/low temp/rh of the veg closet, it went to 86.5F and 85%RH, probably for most of the 9 and a half hours the power was out.

I didn't think about the closet being stuffy and since there was no circulation....fuck. The top layer of coco in the 5 inch square pots have a white mildew/mold coating some of them.

I shop vac'd the top layer off, and I am thinking of making a few gallons of 29% h202 + water and wetting the tops of the 32 pots at 5ml per gal. Think this will suffice? Fuckin bullshit I tell ya.

you people really need to get yourselves a generator... they're not as expensive as you think they are.

thats my only advice.. that's about the only thing you could use during a power outage.


Last summer, I had two DNA Genetics 'Lemon Skunk' plants. They were 7 weeks into flowering.. when a freak thunderstorm came through my area and knocked out the power for 12 hours (little longer than that actually). Luckily for me.. I had already bought myself a generator.. but, when the power went out that day.. I turned on my generator and plugged in my HPS light into the generator. Saved both my plants that day using the generator.. otherwise, I think, even though both plants were well into their flowering cycles.. I still think that 12 or 13 hours without light (plus, the lights off period would have extended this time.. if the power didn't come back on before 'lights off' time.) I probably would have ran into some problems.

either way, good luck.

peace.

Thanks for the luck, what kind/size of generator do you have? Can it run your fans and at least one light?

I have (4) 600w's and (1) 400w, and these fans/dehumidifiers that require the following watts:

30pt Haier Dehumidifier 420w
65pt SPT Dehumidifier 780w

10" vortex vtx1000 (790 CFM) 260w (hepa filtered flower tent light fan)
8" hydrofarm booster (471 CFM) 54w (inline flower room light duct fan)
8" elicent (636 CFM) 160w (carbon filtered flower tent exhaust fan)
6" cap valueline (435 CFM) 120w (carbon filtered closet exhaust + light fan)
6" elicent axc-150 b-c (309 CFM) 72w (hepa filtered whole room intake fan)

Circulation
(2) 7" clip fan 48w
12" pedestal fan 42w
(2) 18" pedestal fan 72w

2148w (fans+dehumis) + 2800w (lights) = 4948w

So I'd need at least a 5000watt generator. And that's not including the A/C which is 1350w. The Kill-A-Watt rocks for grow room power management.

i run a 6000-

not mentioning the grow, it makes life without power a breeze. i wired in to my panel through dedicated breaker, then to an interface, outside. i just start the genny and flip some breakers.

it runs the whole house. albeit, not all at once. but it does keep emergency lighting, fans, and aircon online. also fridge, sump pump, tv's, interwebb, etc.

i bought it off craigslist about 7-8 years ago for 200 bucks and it was a brand new honda engine deal. money well spent.

EDIT: do NOT run sensitive electronics on a generator. it WILL fry them. think, puters, modems, amp heads, and the like. there are commercially available products that will "clean" the power for these types of applications. RV's are a good place to look for these.

Wouldn't Tvs and innerwebs fall under sensitive electronics? And how are you gonna use the super highway without a puta machine?

I'll have to ask my electrician friend about wiring, not sure my box has enough room for that kinda setup, plus I rent, so it would have to be easily undo-able for later.
