Hey folks, as the title says I have been having mold problems during last two grows, haven't lost an entire plant but as they tend to go for the big cola's i did loose quite abit of weed.
The first time i encountered mold i would say it was due to slightly too high humidity which i didn't kept under control.
So this time i fixed humidity, plus its winter so its alot cooler which helps, humidity never went above 40% i would say, generally mid 30's. I dont had a fan blowing on the plant all the time, the fan i use is a little too big for this small grow, but its on maybe once a day (most days ) for an 1hour or so to give it a blast.
The grow is in a bedroom cupboard, i have a small 4" carbon filter i use in the room, and tend to open window late at night to avoid any smells escaping during the day. I smoke in this room too, .
Now much to much annoyance - i have a Green House Auto Exodus Cheese hydro plant finished could have went a week longer maybe more, but i found some of the white fully mold in two/three places, so cut down any near by bud and binned it and planning on flushing it for a couple days then taking it down, hopefully no more spreads.
It wasn't massive amounts of mold, very little in fact and its hard to see with it being white, looks similar to the crystals, but its definitely mold - had a little look through magnifier looks different to crystals. Its late at night and your eyes are tired its easily to miss, and its deep in the nuggets so you have to dig a little to check.
I'm a fairly new grower, only had a few small grows for some medicinal weed, done lots of mistakes during my first grows and tried not to repeat them, so i would like to get rid off mold once and for all hopefully
So for this grow, the cupboard was cleaned before using it, its a hydro auto cheese grow, roots look fine etc, and humidity was good, some nutrient def last couple weeks, but it didn't seem too bad. Plant seemed generally healthy apart from the deficiency towards end. I use good quality nutes, change water tank 20 liter once per week with fresh water and nutes.
My main reason for mold this time i think is the amount fresh air getting into the room and air circulation.
If i had a fan blowing on the plant constantly, would this help alot with mold prevention? Assuming all else is fine.
Thanks for any advice.
