The pre-flowers grow at branch inter nodes just behind the leaf spur or stipule about the fourth week of vegetative growth,when the plant is six to eight week sold. This is the point of sexual maturity,the first sign a plant is preparing for flowering—the next stage in life. You can see pre-flowers with the naked eye, but a 10 to 30X magnifier will make viewing easier. You can accurately determine plant sex after eight weeks.
Using this method, you can distinguish sex before inducing flowering. Male Pre-flowering Male pre-flowers are normally visible when plants are six to eight weeks old,after the fourth week of vegetative growth. The pre-flowers emerge behind the stipule at the fourth to fifth branch inter nodes and generally do not turn into full flowers. But, according to Bongaloid www.
Inducing flowering with 12 hours of uninterrupted darkness and 12 hours of light before pre-flowers develop will stress the plant. This stress could cause peculiar growth, and plants might develop into hermaphrodites. Inducing flowering before pre-flowers form will not expedite flowering. In fact,flowering will occur at about the same time as if you had waited for preflowers to show! A word of caution from bc-trichome-farmer www.
Wait and make sure. Males can flower under long days and short nights as well, but they generally produce fewer flowers. Once male calyxes show, pollen develops quickly and can disperse within a very short time. There is always an early opener that sheds pollen, often within 24 hours or less! To avoid pollination problems, remove males as soon as they are distinguished. If growing male plants, always isolate them from females, so they will not be pollinated. If you are making seeds,pollinating females too early, before the girls have developed many receptive female pistils, will result in a small seed crop.
Male flowers are about one quarter inch 6 mm long and pastel green to yellowish in color. Flowers first develop near the top of the plant. Pollen sacks develop on a short spike and hang in clusters at the base of branches.
Gradually, flowers develop towards the bottom of the plant. After two to six weeks of the hour photo period, fully formed floral sacks split open and shed pollen.
Males are usually taller than female sand have stout stems, sporadic branching, and fewer leaves. In nature,wind and gravity carry pollen from taller males to fertilize pollinate receptive females.
Male plants produce fewer flowers than females, because one male plant can pollinate many females. Males also contain less THC and overall lower cannabinoid levels. Males fertilize females, causing them to stop high THC production and start seed formation.
Remove and destroy males,except those used for breeding, as soon as their sex has been determined. The instant they show sex, separate male plants used for breeding from females. Do not let them shed pollen. Premature pollen sacks often form and open early or are hidden under foliage and go unnoticed until it is too late. If growing from seed, take special care to ferret out male flowers and plants. Growers have reported that bouncing the photo period around and dynamically raising or lowering the temperature have the effect of producing more male plants.
Note that each stimulus involves creating a climate that causes plants to suffer stress. Also, the stressful environment does not necessarily turn the entire plant male; it turns it hermaphrodite.
The most susceptible plants already have a predisposition to her maphrodism. There are several ways to promote male or female plants during seedling growth. This is when female calyx formation initiates, and it is not contingent upon photo period. It occurs when a plant is old enough to show signs of sexual maturity, about the fourth week of vegetative growth,or six to eight weeks from germination.
The pre-flowers emerge behind the stipule at the fourth to fifth branch inter nodes. A pre-flower looks like a regular female flower; most have a pair of white fuzzy pistils. Pistils normally form after the light green seed bract part of the pre-flower has formed. Wait until pistils have formed to ensure the plant is a female and not a male.
The preflowering stage lasts from one to two weeks. A little patience is in order now! Always wait to induce flowering until after pre-flowers appear. This stress could cause odd growth, and plants might grow into hermaphrodites.
Inducing flowering before preflowers form will not speed flowering. Flowering will occur about the same time as if you had waited for pre-flowers to show!
Did you know that making clones is nowhere near as hard as it looks? With just a little bit of effort,such as removing the growing shoots on the lower-most branches by just slicing them off,keeping them moist and then dipping the ends in rooting powder and popping them in a block of stone wool,we are already well on the way. A humid seed tray and a small lamp complete the picture.
Did you know that you should never give your young clones liquid nutrients mixed with water immediately on planting? The small roots of the clones at this stage are not able to stand it and will be irreparably damaged. In the first few days we only give them a little water, possibly with a little root stimulator added.
Did you know that with a Skunk variety, such as Super Skunk, you can achieve considerably larger yields? There are credible stories of up to grams per plant being managed. Of course, these plants have been allowed to grow for much longer than normal and have been illuminated with more than one lamp.
