Humidity Problems

[DurumGallico]

Do you have a good air recycling ? If you don't give fresh air to your plants no wonder why you have mold issues, beside humidity

Hi Mark, I know in fact in the second video I show that it seems too violent the wind on those leaves but I do not have where to put it. that was the only place where it entered. So you are recommending that I raise it up more to not get those leaves and put it directly just pointed at the tops? I've been trying to put it in the middle to catch both under and over the netting as was recommended a few comments above. Other than that do you think it still manages to move air fairly evenly? In the first video you should see it! The speed is set to 2 out of 3 powers! I could set it to 1 but I think then it doesn't reach well enough to the last ones on the left. Thanks for the help

I don't know much about tower fans, can you turn the rotate off, hang it on the side? face it towards the cola's on the second setting, if the fans are a good 1ft away from the canopy the plants should be fine, this should cover more canopy.
If my humidity is high, I would raise the temps up to 30c and cause a vacuum, (turn the intake fan off or block the hole letting air in) turn the extraction fan up full.
When you turn the light off the temps drop and the humidity will go up, so I would use a heater and try and keep the temps 25c lights off

All of the air is passively introduced and then drawn by the extractor out of the room and discharged into the hallway of my home.

Well if you still have mold issues while managing humidity you should increase your air recycling imo.
Actually you can have a really high humidity level, if you have a good air recycling it prevents or at least greatly reduces mold issues.
Also, you have organical preventive treatments, you should use it if you really can't beat mold.

Also, what about the strain ? Always the same ? or you're switching strains but still the same issue ?

Yes, I could stop it but still couldn't move it anywhere else...at each corner are the net hooks. I just don't know how to move it away from the canopy... do you say that even if it's swinging (so not perpetually hit but with a small interval) it could damage the top? I repeat that I could lower the power further but I'm afraid that then does not emit enough power to reach those farther away .. ah and let me know if you think it is better to raise it again! Brother now the problem is no longer the humidity because now are between 40/48% lights on and absurdly with lights off this morning I found it at 38%. I already use a heating mat hanging sideways

Hang it above the canopy next to the light, aiming it down towards the opposite side of the canopy.

To be honest, I've had mold problems a few times only because I didn't have how to manage the humidity and couldn't use extractors or dehumidifiers, let alone make a decent setup. Where I live it is illegal and unfortunately years ago if I wanted to do it I could only do it that way... the last cycle without humidity management was last year and I basically had to throw in a total of 100/150gr for mold but we were talking about a constant humidity at 67/70% with little air recycling. Now I'm just paranoid and don't want to relive that nightmare. Anyway for the air recycle I calculated how many CFM I needed in the extractor. I don't want to limit myself to growing one strain over another just because I have to.

Ohhh, I like the fan that is pointing straight up at the light.

I was so paranoid about the air being stagnant between them that I wanted to add one there as well

ok so if you know it's only bad humidity management it should be ok then !
About strain, that's not what i meant ; i thought if you always have the same issue with the same strain you should consider pick another one with a stronger resistance to high levels of humidity and mold

Sorry I misunderstood! Anyway, for now I try to change strain at every cycle... all with indica predominance, which rightly plays to my disadvantage.
My speech was related to the fact that a few people have directly advised me to go with sativa predominance.
