  • Can PM live in the soil?
  • Would it be safe to reuse the same soil after I culled a plant that was showing PM? Maybe dig out the top layer of soil?
  • Will fabric pots hold spores?
  • I have other fabric pots that were in the same tent that are still growing plants which are not affected (who knows if spores are present dormantly waiting to pop up)… should I maybe spray/soak the fabric pots down with h202, Apple Cidar Vinegar, sodium bicarbonate, or maybe bleach? if so which solution & concentration?
  • Is it true that bleach is not 100% effective & is not an approved method by the EPA? If so, what’s the next best option.
  • Is it ok to spray down fans with straight H202?
  • If I were to use H202 to clean tent should it be straight 3%, 3% diluted 50/50, or 3% diluted 1/10?
  • Do I need a new carbon filter, or just washing the outer filter is ok? best solution to wash filter in?
  • Best way to clean the rest of the tent preferably organic (if possible), but not opposed to whatever works best?
  • Any recommendations on a HEPA filter? Links?
  • I want as much space in tent as possible, so is it ok to run HEPA filter on outside of tent, or it needs to be inside of tent?
 
Ok I am not going to try and answer all of the bullet points but unless you have a mold allergy specifically to PM then you are overblowing it’s significance as a residue. PM spores are airborne outdoors and are in constant circulation. Unless you step into an air lock before entering your tent then you cannot prevent airborne spore entry.


The primary reason I say it is overblown is due to the ability to prevent it. PM is (usually) due to improper RH and lights on/off temperature swings. PM likes it cool and semi dry, 60s are not your friend temp wise.

The real icing on the cake of PM and fungal prevention in general is airflow. If you have excellent airflow then the spores will have a much harder time of growing/living in your tent.

If you already knew this stuff then disregard, only mean to assist

But wouldn’t more airflow just mean spreading the spores even further and really contaminating the whole grow?

Like the wizard mentioned, mold and mildew spores are floating around in the air basically everywhere all the time. It's really hard/expensive to keep them out completely.

The thing to focus on is making the environment such that even though they may be in the air, they can't germinate and start growing on the plants. Keeping airflow up and temps and RH stable and in the right range will help with that.

Flow. Like a River. Release the damn and let the air flow! Mainly in regards to how fast you turn over your air with fresh air.

Upgrade to a bigger in-line fan. Negative pressure your room so all intake air is filtered,

Oscillation is still important but more about turnover

I bought one of these to kill powdery mildew in the air and on surfaces. After a few adjustments I'm now PM free.

Request a quote? Expensive I assume.

Never mind. Saw your last post confirming.
