Drying in grow room with lights on?

[TurboFish]

Iw as wondering if any of you have any advice about drying in a room with lights on. Don't give me the light ruins thc shit tho because it will take months for it to harm the thc and Im more interested in other affects that light might do to drying. I read somewhere that light promotes the chlorophil to stay in the leafs....is this true? anything else bad?

Light does change thc - but who hasn't smoked brick weed which was obviously sun dried and was still nice and strong. So yeah, you can do it. The issue is that you're effectively flash drying it, so it'll taste pretty bad, a cure is out of the question and it'll be rough as hell to smoke.

it sucks don't do it if you are looking to have a good cure.

Below are two separate articles that I found just searching google. As you said in terms of THC degradation, although it most certainly will degrade over time with light exposure, with low intensity artificial light and such a short exposure duration, minimal degradation would be expected. But the bold sentence may be a reason to keep them in the dark.

The second article is for SPINACH yes I know not marijuana but I think it may provide some insight into why its best not to continue exposing harvested plants to light. It seems it maylead to a harsher smoke. Just me speculating at the moment hope it helps.




"The stability of cannabis and its preparations on storage
Fairbairn JW, Liebmann JA, Rowan MG
J Pharm Pharmacol 1976 Jan;28(1):1-7

Abstract:
Solutions of pure cannabinoids, nine samples of herbal and two of resin cannabis (one freshly prepared) were stored in varying conditions for up to 2 years. Exposure to light (not direct sunlight) was shown to be the greatest single factos in loss of cannabinoids especially in solutions, which should therefore be protected from light during analytical and phytochemical operations. Previous claims that solutions in ethanol were stable have not been substantiated. The effect of temperature, up to 20 degrees, was insignificant but air oxidation did lead to significant losses. These could be reduced if care was taken to minimize damage to the glands which act as "well filled, well closed containers". Loss of tetrahydrocannabinol after exposure to light does not lead to an increase in cannabinol, but air oxidation in the dark does. It is concluded that carefully prepared herbal or resin cannabis or extracts are reasonably stable for 1 to 2 years if stored in the dark at room temperature."







Last year, a USDA research plant physiologist by the name of Dr. Gene Lester conducted a fascinating study on the phytochemical metabolism of two types of spinach. He wondered if, since spinach growing in the field relies so heavily on visible sunlight exposure for producing the phytochemicals that make humans want to eat it, perhaps exposing the spinach to light post-harvest continued to affect its phytochemical composition. And so he found out.

Using freshly-harvested, conventionally-grown Texas spinach, Lester’s team measured the various light-sensitive bioactive compounds in the leaves: vitamin C (ascorbate), vitamin K1 (phylloquinone), vitamin B9 (folate), vitamin E (alpha-tocopherol), and the carotenoids (lutein, beta-carotene, zeaxanthin, violaxanthin). The leaves were then packaged into standard clear plastic containers, which were either placed on a shelf with exposure to full retail display lighting or placed in double-thick brown paper bags with zero exposure to light. This went on for nine days. Bioactive compound levels were tested throughout the duration of the study; here’s what changed (or didn’t):

Vitamin C – Exposed spinach had significantly more ascorbate than covered spinach. At day three, ascorbate levels in exposed spinach were greater than original levels at harvest, and by day nine, exposed spinach had retained original ascorbate levels.
Vitamin K1 – Vitamin K1 is required for electron transport during photosynthesis, and it increased in both covered and exposed spinach leaves. Exposed leaves, however, saw generally greater gains.
Vitamin B9 – Vitamin B9 levels were preserved in exposed spinach leaves, while they degraded in covered leaves. Previous studies have shown spinach folate levels to generally decrease with storage, but this study shows that light exposure is the deciding factor – not simply “storage.”
Carotenoids – Carotenoids, as a general rule, increased across the board in both exposed and covered leaves, with exposed spinach seeing more on average. Lutein and zeaxanthin were highest in exposed leaves, while beta-carotene and violaxanthin were higher in covered leaves.
Vitamin E – Tocopherols were “generally higher” in exposed leaves than covered leaves.

Afterwards I want no reactions, slow it all down so molecules can halt leaving them to explode when sparked later.

Orange soda being left out of the fridge goes flat quick and those recharge pumps are bs, I think light and warmth can be blamed.​

lets be real people. the plants were under the same lights for months. i dont think a few days after chop will see any degradation of the product.

 

[greenmatter]

do i KNOW that drying in the light is bad? NO... has everything i have read since 1970 said it is, YES. we all do what we think is best. it is not like your crop is going to melt in the light, but after 3 months of work why fuck around?

some people need to dry in their tent because its the only space they have with a carbon scrubber. I should have told you guys my concern is how it will smoke being light dried vs dark. Now, I could reduce the ammount of light greatly while in the tent, but the buds would still be exposed to maybe 10% of the light without being able to compleatly, "filter" it all out of the "drying sack". dose anyone know what light will do to affect the smoke,burn,taste, and not the "get you high" chemicals aspect of it? thanks for the input so far tho. I think this hasent been talked about enough for people with limited space having to dry in their carbon scrubbed tent for security reasons. more input on this subject would help alot of us out

I will never do that, the lights being on would mean the temps are at 28 degrees.

I prefer to dry my stuff in the dark at 20 degrees or less.

Leaving the lights on will make it a quicker dry and as far as i know the slower the dry the better.

Why do you need to keep the lights on? Keep the clones going? Maby have a seperate place where your veg plants can chill for a week?

 

[Green lung]

This what I do Its works fine, put something up like black plastic or t-shirt, something to block some of the direct light and your good

hang buds on hanger. place hanger in a large paper bag with handles. the handles keep the paper bag on the hanger. make many small holes in bag. hang away from or above the light.
