Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
How to sex a pot plant
A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
Unfortunately, the symptoms of underwatering are mostly the same as those of overwatering (drooping and wilting). However, you’ll be able to tell that your plants are underwatered if their soil is bone dry.
Make sure your pots drain well to protect your plants against fungal pathogens and root rot. If your pots don’t already contain holes (or some other kind of mesh to allow runoff), you’ll need to puncture them yourself.
UNDERSTANDING THE SEEDLING STAGE
Most blogs and forums will tell you that your plants are ready to veg after two weeks, but that’s far from true; it usually takes about 3–4 weeks from germination for your seedling to use up all the energy stored in the seed, although some plants develop faster than others. But rather than going by time, we recommend you transplant and start vegging your seedlings once they’ve developed at least three nodes and 4–5 sets of true leaves.
Cannabis seeds already contain two cotyledons (or embryonic leaves) that unravel and push the seed casing from the shoot. After the cotyledons emerge, cannabis plants will develop their first set of true leaves. These will grow out of the main stem and have just one finger.
Cannabis seeds need four things in order to germinate: moisture, warmth, darkness, and time. To ensure you grow healthy seedlings, germinate your seeds using one of the following techniques.
We’ve all been there; your seedlings look perfectly healthy, then suddenly you find them slumped over the edge of their containers. Within 24 hours (or sometimes less), they’ve shriveled up and died.
Before the seeds turn into a beautiful marijuana plant, they need to be prepped for transplanting, or in other words, they need to germinate.
After you’ve soaked the seeds, put the cup of water in a dark and warm place, and leave them for 36 hours at most. The seeds that have started sprouting will have a tiny white root sticking out. If, after 36 hours some seeds have no signs of sprouting, we recommend you put them in a warm and moist place to encourage the germination process.
Germinating Your Cannabis Seeds
There are three most common germination methods.
Seed germination is the process when a plant starts sprouting from a seed and continues growing from there. During the germination process, the food reserves present within the seed are converted into sugars that the plant uses to increase in size, causing its root to start breaking through the shell. This is the first sign that they have germinated.
Once emerged, the root is crucial to the plant’s survival as it provides the necessary nutrients from the environment. After this process, the germinated seeds are ready to be planted in the growing medium of your choice.
