Mouldy Query

Hi got a grow tent with autos in and are half way through. Im in an attic room conversion and since I moved here, a small bit of mould is near window cills, walls and grows on used tea bags in a week.

I have noticed grey fluff in the holes of the airpots and a tiny bit on soil surface in the tent (I over watered). Plants are clean and happy right now. Its not that budrot specific strain (also its winter in UK).

I was planning on drying my bud in the tent with the fan on and lights off so I doesnt reek the street out without the carbon filter.

Am I fucked or can I get away with it or is mouldy infested buds innevitable?

youre fucked....unless....unless.... you bleach the shit out of your grow and keep a spray bottle of peroxide and water nearby to hit it when it pops up again. You then might be able to finish out

If mold is growing everywhere else it will grow on the plants once they are dead and can't fight it off. What is the RH up there? If you don't have one get a $10 weather station that gives temp and humidity.

Things that can help:
Fungicide (the space not the buds, cover them when you spray)
HEPA (filter mold spores out)
UVB (kills mold, ups your THC/Resin production)
Dehumidifier (30-50% is fine, over 50% and you are asking for problems)
Bleach (your space again not the plants, and .5 tsp per gallon if not on tap water, kill mold in soil/rez with little impact on your plants)
Dry elsewhere (I built a box with RH meter and fan, RH goes too high, fan runs, cheap vacuum 99.99 hepa on intake, flat carbon filters on exhaust)
 
Bugger! Thanks.

The RH in my bedroom (which the tent is in) is quite high, windows steam up and condensation on windows, all moist air from house rises up here. It will be lower in the tent with the lights on, fan and filter.

I have over watered them which allowed the RH to encourage the mould, never leaving extra water in drip trays again!!!! One time I turned my fan off with my light for 4 hours, opened the tent and the plants were dripping wet droplets like it had rained or heavy morning dew. I'll get the RH meter from the local grow shop.

With no pots and wet leaves, drying buds and hanging lots of tissue would reduce the RH further surely.

I dont really have a choice as im in rented shared house and I cant dry it without the dark tent and filter.

FUCK SHIT FUCK SHIT FUCK

I'll have to buy some bleach and hope for the best, will 0.5 teaspoon in 2L water be OK to spray sides of airpots and top soil without killing my plants?

Ill have to deep bleach my grow room before hanging the buds in there. :-(

You have serious RH problems from the sound of it. A weatherstation with RH and temp is available for $10 at Walmart here in the US, I assume you can find the same thing at your local retail supermarket, just don't get tricked into spending multiple times what you need to at the grow shop.

.5 tsp per 2L (half gallon) will be fine to spray, though I would avoid hitting the plant as much as possible. I would go much stronger for spraying the area if you can be sure it won't contact the plant. Chlorine at 4PPM = .4 tsp (of 6% chlorine) per gal = tap water. I would go with 1 tablespoon per 2L if not in direct contact with the plants. For direct contact with the plants I would stick to 5 PPM or less.
 
I hear you there. Wilko's is the UK version of WalMart (minus groceries and food) £3.50 in real money aint to bad hehe.

I refuse to loose my stuff because of this. Its all out war!!! DIE MOULD. Still though the hygrometer will only tell me what we already know (and your 1000's of miles away). Huge humidity issues. Asses!!

In UK there is 10ppm Flouride for dental purposes as well as the Chloride. Im going to try to dry out the pots (like I should have done) and try a 1 Tablespoon 10ml in a liter of tap water and hit the pots and soil, I can wrap the stems in clingfilm but as they are airpots, the holes may have air-pruned roots popping out. Will the makeshift fungiside get uptaken by the roots and kill the plants? I can easily avoid spraying on the plants above soil easily.

As the buds start to cover the stems I could spray 3% vinegar onto the bud sites and plant to kill any hidden spores that could rot the bud from the inside out. What do you think? Im also going to apeshit medeival style with the bleach on the mould outside the tent and try to curb the amount of spores in the air (little buggers)

GAME ON MOULD

I would focus on the mold everywhere else before hitting the plant with anything. No idea what effect vinegar will have on the taste of the buds. Is mold, "mould" one of those weird words that are spelled differently in the UK? After you bleach the area around the plant I would use a fungicide on the same area to prevent growth in the future. It will leave a dirty water spot appearance, but you don't want to wash that off, that is your protection.

Example: www.amazon.com/GARDENTECH--2115-DACONIL-FUNGI-CONC/dp/B000RUGIY0

Get UVB too, it has great effects on the weed and a nice side effect of killing mold.
 
good call, the mould (yes its one of those weird words that would fail you in an English exam and get marked as poor English in a university essay/exam etc if you spelled incorrectly as 'mold') came from outside so I should deal with that 1st, good call.
Thanks for the fungicide idea too (trained agronomist should be able to find a decent one for that) Vinegary buds??? that could be nasty.

UVB I saw some things on this, wont it degrade THC?

Yes and no. It does degrade THC, but by doing so it stimulates the plant to produce more THC/Resin and it also recycles the degraded THC (CBD or similar) back into THC. You don't want UVB to hit them after they are cut, or for a few hours before they are cut, but otherwise UVB is good if you don't go crazy overboard. THC is produced partially as a UVB protection mechanism for the plant and especially it's seeds/buds. THC = Cannabis Sunscreen basically. It's other purpose is against insects, and some people like to simulate insect attacks to stimulate THC as well, no idea on how effective that is.
 
Nah its grey fluff, its living on the damp I think (im guessing and trying describe) its not funny coloured, blue hues maybe. Its an opportunist mould, defo not bud specific, why do you ask pal?

so tell me is it all over the medium and pots plants ect or grow room windows tents so on ?
 
wow nomo awesome bit of canna-knowledge there, I did not know this. Thanks.

I just read that only UV light (from white light in the visible spectrum) I have a duel spectrum 300W CFL with only 2700 and 6400K, could I use this when drying?

(sorry for being a twat about the spelling :-) )

Are you certain it is not mycorrhizal growth? Did you use beneficial microbes? It might be good for your plants.

Any light during drying will cause some degrading of THC. I wouldn't dry under UVB or Grow lights (standard indoor lighting is fine, minimal effect), instead filter the intake air with a cheap 99.7-99.99 HEPA and get the first portion of the drying done faster than preferred.
 
its grey mold. Not black. It came from outside the growtent, mold on window cills when I moved in, not too bad just a little.

Only on media surface not the tent or the plants or the floor. Its not hurting the plants right now, but like Nomo said, as soon as I chop them and the hardy auto mold resistance enzymes will all stop fighting the mold and it will cover my lovely drying buds :-(

With humidity levels at the point of seeing dew, he is going to have mold/mould of multiple species. If the bad ones aren't showing their face now they will be soon.

Fixing RH issue needs to be #1 priority. But need to kill the existing stuff and prevent too at this point. mycelium isn't likely to grow on the window either.
