So you have worked hard for 8 weeks! You have invested money into equipment and possibly genetics; you have invested time and dedication to get to this point. How can you tell when it's time to harvest your gooey girls? Well 'fire one up' and let's take a look at the best way to be sure you're harvesting at peak potency, or at least you will better understand what happens in the final weeks, so you can harvest for the specific type of high you prefer.
The harvest window is one aspect of the craft which unfortunately, gets over looked or the grower simply doesn't have the patience to wait-out the last few days, to insure max THC content. Some strains are better harvested before their peak THC production and some are better harvested after their peak THC production. This is what Robert Clark wrote in his book "Marijuana Botany" about trichomes and what they tell us; "The elevated resin heads appear clear, since fresh resin is still being secreted, often being produced in the cellular head of the trichome. At this time THC acid production is at a peak and CBD acid levels remain stable as the molecules are rapidly converted to THC acids, THC acid synthesis has not been active long enough for a high level of CBN acid to build up from the degradation of THC acid by light and heat. Terpene production is also nearing a peak and the floral clusters are beautifully aromatic. Many cultivators prefer to pick some of their strains during this stage in order to produce marijuana with a clear, cerebral, psychoactive effect It is believed that, in peak floral clusters, the low levels of CBD and CBN allow the high level of THC to act without their sedative effects."
What the hell does this mean?

When growing Indica hybrids, unless you want to end up on the couch, it's best to harvest when the trichome heads are fully formed but before they start to cloud over and turn amber. According to the maturation time of the specific strain this could take as little as five days or as long as two weeks. If you allow an Indica to go too long you can dramatically affect the taste and high. Fortunately going too long is not a real problem for most people. I like to study close-up photos taken with a high resolution digital camera; however an inexpensive hand-held microscope works wonders. It almost looks like you are in an alien world when looking at resinated buds using fifty-times-power.

Take for instance the Jacks Cleaner harvested at fifty-six days; all trichomes are still visibly clear with very few turning cloudy. At this point it has a very 'up' high and an 'in-the-head' buzz. I get some good visuals and the lemon flavor is sour and a tad tart. The same plant, left just one more week at sixty-three days flower; the trichomes have turned milky white and a good portion, about thirty to fifty percent, are deep amber almost the color of cola. Taken at this time the smoke is heavy and thick, the lemon zing has been replaced with a musty sweet lemon smell that reminds me of 'Lemon Heads' candy. The high is now all body high and very much a sedative. We would smoke this only as our night time medication. It is almost an example of a plant taken too late, however we do this because of the medicinal properties she takes-on at this late stage.
Another example is Killer Queen. At forty-nine days flower, she has a candy-like smell and taste with that same 'up' high. If you were to harvest her at sixty days flower, she becomes 'Super' Killer Queen, with a more skunk-like smell and a thicker trance-like high.
The mistake to try and avoid is harvesting before the trichomes are fully formed, so as mentioned in the guideline; most growers whom use this method, harvest at the point in which the majority of the heads are cloudy. Harvesting before this window will produce bud that is less potent, containing less essential oils and trepans, causing your finished stash to take on a grassy or green taste, even if it is dried and cured correctly.

Another good method would be harvesting some of the more mature buds, usually being the upper or main colas. This will allow more light to shine down on the lower portion of the plant, not only will the buds mature further but they will also pack on some extra size.
If you have a nice digital camera with a macro feature, try taking some close-up photos and use a photo editing program such as Adobe. This will allow you to zoom in close so you can see what the necked eye cannot see. If this is not an option, Radio Shack sells battery-powered hand-held microscopes for about fifteen dollars.
Take advantage of this information, it will help maximize the results of your favorite strain, or help you determine the harvest window of something new.

Timely and very informative. We are growing 9# Hammer and Agent Orange currently. 9# is hands down one of my favorite strains for my nightly goal of staggering off to bed, so sedated I hardly remember making the trip. Just harvested 9# at 13 weeks of flower under T5 red spectrum lights. Tons of amber on the sugar leaves, not so much on the calyx. Space considerations are our main limitation - stealth cabinet grow. But damn, 9# has been an amazing plant and a great producer. Even with T5 lights, she put out decent flower on the lowest branches - never had a plant with lower branches bent under the weight of the flower.

I live in a legal state and can contrast/compare with our own home grown. WA state has a lot of great weed but there is nothing smoother than your own grown with organic nutes and no pesticides. Just can't get that level of smoooooooth smoke from rec store weed.
