Cleaning grow tent for next run

Rurumo said:

Totally agree. If you've had a mold problem and you don't clean like a maniac, you will have it again. Even if you do clean really well, there are probably still some spores floating around, so you should preemptively treat your next crop with biological fungicides from day 1.

Just run an ozone generator for 30 minutes. All problems solved.

I just sweep and clean down with bleach water...

That isn't true, mould spores are around us and the plants 24hrs a day, its a bad or suitable environment that allows them to grow.

Just completed my first post-harvest clean in the new tent. I had had issues with PM that I was able to get under control with Potassium Bicarb. mixed w/water - 1Tbsp/half gallon w/drop of dawn detergent. Since bleach is a no no for me (screws w/my sinuses plus the smell makes me want to puke), I thought I would spray the inside of the tent with a hotter mix of PB - 1 tsp/quart of water. Let it sit for an hour w/all fans off, RH was up to 87%. I'm hoping that any spores in there got roasted although I'm sure I will be fighting PM forever as it's pretty bad in my area. Garden veggies are often hit hard.

I'm actually kind of shocked to see how people clean their tents. I Vacuum and use a damp cloth to wipe the floor. That's about it. Cloth pots get rinsed in a sink before going in my washing machine and dryer. Never had a problem.

I was shocked when I got PM inside the tent. Never thought it would happen as my buddy's ben growing in a tent for 3 years w/no PM at all.

PM is VERY strain dependent IME. If the environment in the tent is good and you're still having it, get another strain

I think this is mildew?

Its never ever been in the tent or any other grow room, imo its because the conditions inside won't allow it to grow.

yup looks like it to me. I would scrub that with some clorox or something asap.

Your solution is at the top of this page.

Nobody listens to Turtle.

ISO Alcohol. 70% is pretty cheap, few bucks for plenty enough to put in a spray bottle and spray the whole tent top to bottom

"run an ozone generator for 30 minutes"? I did see that and will look into getting one if PM gets really bad. So far the PB spray has been keeping it in check.

Well I've never had PM in 20 years of growing. I imagine that if I did I would clean things after that grow, but I don't try fixing problems I don't have.

After cleaning with bleach and before a grow. I spray the walls, floor, plant shelf, and ceiling down with copper fungicide. I usually prep the grow room three days before sticking a plant in it. Making sure everything works, everything is clean, and the preventive measures. Copper wire in the humidifier water, BTI mosquito dunk in the drain tray. AzaMax and BTI on the coco.

I've never had mold. On a surface or plant. Never had a jar mold either.

Why is your tent black? Seems like a poor design.

Okay, but do you really want to spray it all over inside your tent? You would literally have to coat every surface.

I didn't even pick up on that when I first saw the pic.

If you wiped everything down with hydrogen peroxide solution then you're good to go. Nothing should survive that. At all.

Make sure you also clean fans and filters if possible.

Took all of 10 minutes to hand spray the inside of a 4x4x6. As I mentioned, this is my first cleaning venture. I went with what seemed to make sense and was easy. If the PM comes roaring back, even after regular PB spraying during veg, I will look into a more effective method.

Ozone Generators don't spray anything they just emit o3 gas into the air. You place the unit in the tent or room and let it circulate for a while and get enriched. It will oxidize everything though so its not really safe to have equipment in the tent like lights etc as it will eat away at rubbers and soft materials quite impressively at enriched states.
