I get this a lot in my RDWC tent. That's why I defoliate and that's why I've been putting up with the windburn from the floor fan. Otherwise, all the leaves in the middle are wet to the touch.

That wind burn. I've been looking at plants for a while and I couldn't tell you what windburn is. Have you actually had it? I hear of it all the time and watch for it but never have I seen it. I want to say it's an imaginary thing but it's so common to hear I just don't.

I agree genetics. I had a Wedding Cake herm, I thought it was the lights, but her clone did the same thing.

The trick is to know that you really did do something horribly wrong to make it happen. Then they're good seeds.
When they up and decide to herm on their own, then they're ng to me.

Good to know.

I kept some of the seeds. I’ll piff them.

I do get windburn in my RDWC tent. The floor fan blows vertically from bottom-right to top-left. Any leaves in it's path turn brown, shrivel up and fall off. I leave them on as long as possible because if you remove them, it just starts on the leaf behind it. I'm hoping the new Vivosun oscillating floor fan will solve that.

I usually get the wind burn on the outer edge and it's most concentrated directly in front of the box fan that's running hard. I've never noticed the burn from the high mounted fan that's blowing down. It's also farther away from the tops of the plant whereas the box fan is about 1.5' away.
I don't think I've ever taken a picture of it. I know what it is, and I just make my ocd arse leave it alone. :rolleyes:

Hi Keffka. On my first grow, I did some experimentation with Govee RH sensors around the plants. I saw that without good airflow on the plants themselves, the plants create their own little microclimates and can be 10-15% higher in RH than the tent. Since then I've always had fans blowing directly on my plants. I also noticed that the bottom and top of the tent could be 5-10f different. Unfortunately, in the RDWC tent the only way to fix that is to blow THROUGH the plants.

I usually have a couple of canopy fans blowing on the tops, along with a floor fan or two blowing up diagonally through the canopy. The floor fan always left a trail of wind-burnt leaves because it stayed in one place (before new fan). The canopy fans oscillate and don't cause any problems, except some little marks where leaves rub together.

I've read where these plants are reactive to wind, as usually the wind-side plants are more prone to pollination. I know the wind helps keep bugs off the plant and helps prevent powdery mildew. It also helps build stronger stems in veg.

I LOVE the @VIVOSUN fans I have now. Not only do all of the fans oscillate, they are also in 'Natural Wind' mode. This means the speed goes up and down to simulate natural wind, rather than staying a static speed. With both of these, I feel very comfortable having the fans blow directly on the plants without stressing them.

That said, I'd love to hear some other opinions about this. Anyone else point their fans directly on their plants?

Sounds logical to me but I couldn’t say one way or another. CL

I rotate my plants all the time. I figure whatever the fans might do won't have time to get done! :Rasta:

I rotate my plants when not in the scrog, too.

Medium - 5 gallon SIP bucket with FFHF soil

Mar 23 2023 *** Drought Day# 3 ***

I got the idea to start weighing Emmy this morning. She weighed 25.8lbs / 11.7kg. I'll continue to weigh her through the drought. This should give me a good feeling of how much she's still sucking from the soil daily, and when the soil has no more to give.

I also backed the light up two clicks to start reducing the DLI and the heat in her last week or two. I'll back it up a click or two a day (if I remember) going down to around 35DLI.

I backed the light up a couple more clicks. It's reading around 35dli across the canopy, which is where I'll leave her until the end.

I'm seeing the weight go down about 1kg/day, which means she is still drinking.

Her lower leaves are starting to go limp and shrivel up. I expect to see that same thing move to the middle, then finally to the upper leaves.
