Does anyone know when a plant is at it's highest levels of CBD? When is it best to harvest? I do not know if taking longer would benefit ot not? Thanks

i harvested about 10 plants about 1 month in and they were fairly high in cbd

[who dat is]

I don't know any good info on this either but hope somebody chimes in as I'm curious about this as well.

How do you know, did you have your plants tested?

[Huel Perkins]

Harvest them the same way you would any other plant. Judge harvest time by flower production, water/nutrient uptake, fade, calyx swell, and trichome color (cbd strains seem to show a little more amber).

CBD does peak slightly earlier than THC does, so if you desire a higher CBD to THC ratio you can harvest a few days early.

as long as possible, i would suggest this: just make sure that every trichome is brown and flush another week then harvest. that way the cbd will increase but the thc will drop. good luck

Grown many cbd strains and lab tested many times to back that up?

when it is ripe.

Obviously not one of you knows the true answer, I want proof....not guesses and "when it is ripe" answers. If CBD levels are higher sooner than THC, do they drop sooner than THC? If you are just guessing, save your breath.....I can guess too. I want proof

[Chunkypigs]

if you want proof I suggest you read the GW pharm patent literature for their sativex and epidiolex extracts…. max cannabinoids in ripe plants.

or ask Jesus, he's got all the answers!

Here is something from CannabisNow:

"The grow: Harlequin is a fabulously frosty, clone-only strain that flowers quickly and requires about 60 to 70 days to finish indoors. Unlike most strains, an extended flowering time for Harlequin can actually diminish its effectiveness, because CBD degrades earlier than THC. Thus Harlequin generally tests at around 7% CBD at 10 weeks indoors while at 8 weeks, it can deliver CBD levels as high as 11.9%."

I also would like a definitive answer on this question. I have 3 Harlequin plants about a month away from harvest and would like to know if any of the above is true. The last Harlequin I harvested went for about 9 1/2 weeks and it turned out a little bit 'stoney' for me. I would love to know if harvesting early would increase the CBD and lessen the THC.
