Question on when to harvest ?

For some years now, I've always wait till my buds are mostly amber in color before harvesting to set out to dry. This has always given me a strong head high, or what some may call couch lock. But now that I've moved on in years, I need something more for old fart pains........ so what or when could anyone please tell me when should I cut them off to be best for a body high rather then a head high..... I have always just wanted strong shit in the past. but how do I achieve this type of high? Dose it have to do when harvesting or is it that I have to grow a lesser THC gene? Thanks folks for any feed back... or is there any where that I can read about this on the web? Thank you

imvho, if you want a body high, grow an indica, or indica dom. strain, and if you want a head high, grow a sativa..

i'm a believer in that the different color trics are doesn't really effect the type of high you get from the bud, just one is premature and one is not.. i always prefer to grow the type of high i'm after by growing that type of plant, either indica or sativa, and growing it to maturity..

Mr. Racerboy71, your thought (.02) goes along with most of what I been seeing on the web by experienced growers. I real appreciate it, thank you.

Makes good sense.
Why try to make an apple into an orange.
Just grow a daytime and a night time.
And a lunch time, brunch Ect

I too am a firm believer in the school of growing sativa or sativa dominant strains for the racy/head high and indica or indica dominant strains for a true couchlock high.

Clear trichomes = Immature

Cloudy/Milky trichomes = Mature

Amber trichomes are nothing but a sign of the THC degrading to CBN,not to be confused with CBD.
