11. Harvesting Too Early – Have patience, good things come to those who wait. It’s not the end of the world if you harvest too early, you’ll still yield some decent smokable weed, but you will get a much higher quality product if you wait until the right moment. Exactly when that moment is varies for different growers, but it’s nearly impossible to determine with the naked eye. Invest in a jeweler’s loop or other high magnification device (electronic or digital ones are good and cheap these days) and carefully examine your plant’s trichomes – the resinous glands on the surface of the leaves and buds – at various points in the growing process. Notice that in young plants the trichomes are clear. As harvest time approaches, the trichomes will turn opaque and milky colored. In most people’s opinions, the time to harvest is when most of the trichomes are at this stage. However, some people like to wait longer, until they start to turn amber in color. Conventional wisdom holds that the more amber the trichomes, the more likely the cannabis is to induce couch-lock – a heavy, sleepy, full body stoned effect. Harvest according to your preferences, but always check out the trichomes under magnification before harvesting.
