im not actually in a greenhouse. It’s an outside bed with plastic over them as an “umbrella” of sorts. All of the sides are completely open

Yea I’m definitely thinking about leaving fans running on all night long till harvest. The only plant that has any rot whatsoever is my early SFV because she got violated by budworms before I started spraying BT weekly.
As and I noticed some new red-colored eggs on some leaves so will spray BT after rains pass. These bastards really have a death wish.

Hope they don't become an issue. Beautifully ugly creatures.

I've noticed a ton of grasshoppers and moths this year. More than I ever remembered before, are people seeing this in other areas as well?

I grow in a greenhouse. The way I designed it there is constant natural airflow through the plants. No fans required. No problems.

I use the basement method, to paper bags, then big ass ball jars and I use big packs for long term storage.
Seen only three caterpillars so far this grow, and no piles of caterpillar poop. Have sprayed B.t. seven times since seeing the first one on August 6th, and the treatment plan seems to be effective so far. Doing it roughly every five days, and re-applying sooner after heavy rains.

Some pics from this morning
I have a vent on my roof that is the same as that, side louver and keep my door open during the day. I also live between a stream, river and surrounded by wetlands. Oh, and in a valley that stops most weather, including wind most days.I grow in a greenhouse. The way I designed it there is constant natural airflow through the plants. No fans required. No problems.
Without a fan they could be outside with no cover at all and not get wind for a significant amount of time each day.

It's convection. Warm air rises. The sides roll up and air comes in under the plant canopy, it gets warmed and it goes up and out through the ridge vent.
I have it automated on a schedule or to close everything if its raining.
That is really cool.
Mine is a poly carb and does not roll up or do anything crazy, the vent is one of those wax ones that opens at 70 degrees and closes when it cools down. This is my first go at a greenhouse, but I've been learning a lot and a system like yours for a future set up would be great. Would love to see some more photos if you ever get a chance/willing to show them online.

A setup something like yours is what I’m planning on for next season for sure.

if you have power to the greenhouse an exhaust fan helps a lot ... I use an inkbird to control mine ... it comes on anytime the temp goes above 75 or the humidity goes above 70 rh. I also have 3 other circulation fans going 24/7 ... i'm surrounded by wetland and have no issues with humidity at all ... in fact it's so dry in there I gotta watch out for spider mitesThat is really cool.

Headroom should also be a major priority if you're building a gh ... whatever height you think you'll need, add 2 feet, without question ... my ridge is at 12' and I had to bend over about a half-dozen tops mid-way through stretch to keep them from touching the ceiling this year

If you have the space, bending them over is the way to go. It makes the buds on the nodes grow up away from the stem giving nicer fuller bigger buds. They don't have the big notch in them where they grow around the stem. It's almost makes them more like apical buds - bigger and more symmetric instead of interconnected.

I agree, I've noticed supecropping increases yield more than any other technique
