Wtf why do my plants stress everytime I move them from veg room to flower room

77-80 deg
60-65% humidity
Indoors, the temperature should be closer to 20C/68F.

That can either be from lowering the room temperature or increasing ventilation.

Outdoors you can have much higher temperatures if the plant has a constant water supply and there are wind and evaporation from the soil to keep them cool, nor are the temperatures constant like they are indoors.

Also outdoors, to prevent light damage to the leaves, you can cover them with horticultural fleece until they toughen up. I have never tried that indoors, however it may be worth looking into.

I cloned at 80 deg
Vegged for weeks at 80 deg
Transplanted from cups to 1 gallons at 80 deg
And as you can see the plants looked good
No stress

Within 48hrs after harvest my plants start purpling
Chlorosis necrosis and the environment is the same.

Its ETHYLENE!!!! Damn you ethylene
Who ever said it above thanks

Makes sense on why whenever I pick my plants turn to death.

Just .5-1ppm of ethylene can poison plants and my big drying crop is releasing ethylene

No vents or exhaust fans just a sealed room

Will be installing an exhaust fan in the drying room tomorrow though.

Comfortably numb!

I hope you have an exhaust fan in your flower room! min exchange rate is 30/hr. How do you adjust/control your humidity and drying temps in your veg/drying room, without an exhaust fan?

I use an In room a/c and a mini heater for temp control.
Humidifier/dehumidifier on a controller for humidity

100-150ppm is typically used for ripening fruits, which is a problem for things like cabbage and lettuce. Propane burners are a source, and we use them for co2 production. If this is ethylene related, more pics should be available from propane users.

While some plants can take high levels of ethylene like mentioned above, others like tomatoes just .5 ppms is toxic. It's hard to find ethylene cannabis info but I know cannabis and tomatoes have lots in common.

While co2 burners can produce ethylene so do your plants. Ethylene is a gas hormone that plants produce and releases under stress.

The tomato is a good analogue. From the groups I saw, I'm surprised it's so easily effected.

A proper look shows it's quite an issue. With common attacks on the plant causing production to levels that hurt it. It's used in many processes. We block receptors in females to make males. While it's effect on chlorophyll strips green from fruits, allowing other colours to show in an artificial ripening process said to be natural. Which may fit your pictures. But pics I saw of a growing tomato plant showed downward cupping and curling on weak looking plants.

There was an article on the venting requirements with propane heaters. Quite in depth, talking vent and stack heights for the btu outputs. I don't think we struggle that much, but I'm taking it all in :)


edit: While your focus is on drying time, I'm interested to see if regular venting has a positive effect on your plants grow cycle.

I'm also curious if venting say once or twice a day to exhaust any ethylene buildup would help. especially after I lollipop/ defoliat my plants and put um through that stress.

On the flip side having a completely sealed room during flowering might be beneficial to allow some of that ethylene buildup.

Ethylene is a natural plant hormone made to ripen its fruit or flowers. If you go and suck that away from your plants you could be hurting there ripening process.

I've been meaning to brag about my new drying closet, but I figured everybody else was probably already on the same page.

But.. fwiw, I just had the most notable success in my little grow "career" building out a tall narrow drying cabinet with aluminum window screens installed horizontally every 3" all the way up and only throwing bucked nugs, flarfs, and trims in der with a uh... this thing.. pumpin out the top 24/7.

Put the rest of the stem and leaf and roots and everything else somewhere completely separate to dry, with the intention of minimizing ethylene buildup.

Takes up ... 75% less space? Umm.. finally tastes right?
