  1. This is often repeated nonsense that any seasoned grower ought to know is misleading and untrue. Anyone who has grown a single crop will know that buds don't all mature at the same rate, and don't all ripen together. You can have ripe buds on top with unripe buds underneath, or ripe buds on one side with unripe buds on the other. Following this poorly thought through advice to the letter will either mean harvesting the whole plant when you've seen a few amber trichomes on the top buds, or waiting until the bottom buds have amber trichomes before harvesting anything. This is even further compounded when using low intensity lighting methods. Those who repeat this "advice" never mention the huge differences in growing methods, and are either presuming you will harvest the whole plant when you see the first amber trichomes, or they are presuming that you will harvest each bud separately as it ripens, and that you'll perform this microscopic exam on every individual bud before harvesting it.
    The truth is, you'll never catch all the buds in their prime, but there are FAR worse problems you need to be aware of, like how to spot mold and what to do about it. Stand around with your microscope waiting for every bud to have amber trichomes, and you'll know all about mold soon enough.
    So which is it? Harvest when you first see amber trichomes, or when the plant has 70% amber trichomes?
    NEITHER!!! This is a foolish and arbitrary rule. It depends on other factors, like how intensively you've grown your crop, how far apart they are in their development and how the final feeding and watering has been timed. Light levels are key, and it makes far more sense to judge each bud on its own merits, especially in natural light or low intensity set-ups. If you have time, you can allow each branch to naturally ripen before you harvest it, watching out for any mold of course, but If you have a schedule, and that entire crop must come out at the same time, then obviously you'll have unripe, and possibly over ripe buds in that crop. For optimum quality, harvest over the course of a month, starting with the most mature buds, and allowing the lower buds to ripen at their own pace. Someone growing enough for themselves shouldn't have any problem with harvesting like this. It's only the larger, more commercial operations that can't get a consistently mature crop, because of the greedy way they are growing it. If you are just trying to grow some for yourself, under natural, or low intensity light, then just stagger your harvest over a month or so, allowing the less developed buds to catch up.

  2. Do you pay attention to fox-tailing and calic splitting at all? Ive been doing it for about 16 years now and i find when the calics begin to burst out of the bud structure, 75 to 95% hairs are, brown, and we have tricomes about 10% clear, 70- 75% couldy and 15-20% amber. I think you should try and look into and mention calic development though, its a vastly overlooked visual que in 95% of any videos and in my opinion an equally important one!
    Edit: You do a great job on the things you DO cover. I feel mentioning this may not only help you, but by extention the masses you educate. Hope it doesnt go un-noticed!

  3. When you let it get to the degraded stage there's more cbd. That's why they call poorly processed pot wheelchair bud. The high cbd puts you down. (Think cb-down) I mean the crappy weed that made el chapo a household name. The kind that makes you incredibly burnt out. I mention this because some grow specifically for cbd. You can pick strains with high cbd content but if you time your harvest for a more degraded trichome the cbd levels will be higher. Any weed snobs may not appreciate the sub-par quality but if it's for medicine or edibles anyway it can give you more desired effect. At least that's what Ed Rosenthal said in his high times column. After legalization everybody became a self proclaimed expert about weed science but a lot of what's being said isn't the same as what high times, N.O.R.M.A.L.,or any old school growers say and until marijuana is rescheduled science cannot legally happen so where these scientists and doctors get their data stumps me. The only conclusion I can reach is that they're all full of crap. A lot of internet content is recycled and spread around whether its correct or not and the subject of weed will get clicks. Anyway, maybe some future content on this subject to clarify would be appreciated. I'm not a scientist but I've grown a lot of incredible weed with my family who has done it more than 50 years.
