Cannabis white hairs

Beside a stipule which is itself a green hair like growth on the stem, you will see the preflowers. You are hoping to see a wispy white hair at the node. If you see any kind of ball and no hair you’ve got a male. Until you can see a white hair emerging from a few nodes you really can’t be sure you’ve got a female cannabis plant.

Pistils tend to poke out from nodes pretty randomly on young cannabis plants. Carefully inspect your cannabis plants and you will spot preflowers sooner or later during vegetative growth. Sometimes they are obvious, close to the top of the plants and easy to spot. But this is not guaranteed so really examine the plants carefully.
Before the advent of microscopes and zoom lenses, ganja farmers had to rely on their intuition when harvesting cannabis. The good old-fashioned eyeball inspection of cannabis flowers is a tried and trusted pre-harvest practice. When 75% or more of the pistils are full of vibrant colours, most cannabis growers will call time on cultivation. Flowers covered in red, orange, pink and brown hairs are definitely mature.

Autoflowering cannabis plants tend to suddenly erupt with flowers quicker than you would expect. Somewhere between day 15-35 post-germination, your feminized autoflowering cannabis seeds will have multiple white pistils bursting forth from the first flowers. A week or so later and buds are beginning to swell up with calyx’s and sparkling with resin. Pistils will rapidly change colour from white to orange/red in days rather than weeks.
Female plants and intersex plants will display pistils. Unfortunately, intersex plants will also produce pollen and are as great a threat to your females as a rogue male cannabis plant. Moreover, stress can cause any cannabis plant to develop intersex traits. Some varieties of industrial hemp are bred specifically for their hermaphrodite characteristics.
You may have to wait as long as 8 weeks of vegetative growth with some strains to confirm female cannabis plants. However, after 4-6 weeks most growers can at least weed out the males. And keep an eye on one or two uncertain plants in early bloom if need be.
Do you want Sensimilla? Then you need to make sure none of your female plant’s pistils get pollinated. This means you must continue to monitor your plants throughout flowering. Disturbances in the dark cycle are perhaps the greatest stress factor that contributes to hermies.
Instead of focusing on producing more resinous flowers the female cannabis plant begins to develop seeds. The cannabis will be less potent, and seeds will form in the bracts that contain the ovule. Sensimilla, which means seedless, is entirely dependent on female cannabis plants not getting pollinated.

Cannabis growers that understand the cannabis life cycle and can tell the difference between male and female plants before flowering will always enjoy more success than the witless weed grower. Pistils can tell you a whole lot about your cannabis plants. In this blog, we take a closer look at why they are so important.

Whether you grow your weed from autoflowering, feminized or regular seeds, it pays to know about pistils. Here’s what every cannabis grower needs to know.

Cannabis white hairs

Try to make sure that the humidity stays below 50% in the last few weeks of the flowering period. If the humidity is too high, this can lead to stone hard buds, which might develop mold in the last weeks of their growth phase.

Because there are still a lot of nutrients in the medium (the precise amount depends on the medium you used) and because the leaves also contain a fair amount of nutrients, you can stop administering them in the last 1.5 to 2 weeks (depending on the medium you use). Depending on the cannabis strain you grow and the climate of the growing area, the maturing takes some time to complete.
Suzy’s Tip:

Now the harvest is getting closer, it’s time to remove the leaves around the buds and the bigger leaves that contain THC. This can also be done later on, but if you do it now, you save time and more light will fall on the lower buds, which allows them to grow a bit more at the last moment. You can dry these leaves to make kief, hash, hash oil or ice hash from it.

Beware:

If you have discovered mold in a bud, it is as good as lost. Once 80% of the hairs have turned brown, it’s time to prepare for the harvest. You can influence the type of high you get from smoking your cannabis by harvesting the buds a bit sooner or later. The longer you wait, the stronger the ‘stone’ of the cannabis will be. If you harvest a bit sooner, you get more of a ‘high’ effect. The harvesting time, therefore, depends on your personal preference.
A bud that died or has been infected by mold will also develop brown hairs. You can start harvesting when 80% of the hairs are brown. If most of the buds have brown hairs but a couple of the lower buds still have white hairs, you can still start harvesting. In order to try out the different highs, you can also harvest in phased intervals.

After weeks of increasing tension and enthusiasm, the long-awaited moment of the harvest has finally come. Your plants should look magnificent now. You probably have a hard time waiting to smoke your first homegrown joint but have a little more patience. You only have to wait a little while now and then your time and energy will be greatly rewarded. The plants have grown a lot in the first weeks of the flowering period and underwent a real transformation, after which the formation of the buds began. More and more white hairs were growing and the separate little buds steadily grew inwards to form one big bud. After about five weeks of flowering, there will now be hard, crystal-rich buds on your plants. They should still be beautifully green and the buds should still be growing, even though the major part of their development has already been completed. Production of THC is now at full speed. The leaves around the buds will become increasingly sticky because of the many THC-rich resin glands that are growing.

Because blooming plants need more phosphorus and potassium, you can give them PK 13/14 as an additional stimulant for their growth and flowering. It will make the buds harder and more compact. You can also administer additional products such as blooming stimulators, blooming boosters, and enzymes. If you are a beginning grower, these products are probably superfluous because they are only of use if everything went well during the growth period. There’s a fair chance that you will have made some mistakes if you are a beginning grower. If you are an experienced grower, these products will enhance your harvest.

In the last two weeks, the buds will mainly mature and grow no more in size. The white trichomes (small resin-secreting stalks/hairs) on the buds will now slowly turn brown. Once 80% of the hairs have turned brown, it’s time to prepare for the harvest. You can influence the type of high you get from smoking your cannabis by harvesting the buds a bit sooner or later. The longer you wait, the stronger the ‘stone’ of the cannabis will be. If you harvest a bit sooner, you get more of a ‘high’ effect. The harvesting time therefore depends on your personal preference.
