Make sure you have enough two-inch pots filled with the growing medium of your choice ready. If you’re using soil , make sure it is loose and airy; poke a hole about 1cm down with a pencil. Transfer the seed using a pair of tweezers to pick it up gently. Drop it carefully into the hole you have created and lightly cover it with soil. A spray bottle is the best method of watering your seedlings at this stage, but be aware that if you overwater them, you could suffocate and kill them.
Make sure you pay close attention to the seeds, and within a week or so, a seedling should emerge from the soil. Marijuana plants are at their most vulnerable during the first couple of weeks after germination. Rodents, insects, and other pests can destroy your crop at this stage, so we recommend adding a transparent dome cover to protect them if possible. A cheap and easy method is to create domes from plastic bottles. Simply cut a bottle in half and place the lower half over the seedling; make sure there is enough ventilation. Dropping leaves is one of the most common symptoms of overwatering. As for nutrients, it is unnecessary to add any if your seedlings are already in nutrient-rich soil. High-quality potting mixes should be more than enough in the first couple of weeks.
Although it can vary by a couple of degrees one way or the other depending on the strain, try and keep Headband seedlings in a room with a temperature of 73 degrees Fahrenheit. If the room temperature is too high, the leaves will begin to curl up. At this stage of their growth cycle , marijuana seedlings need 18 hours of light and 6 hours of darkness per day. Fluorescent lighting is energy efficient and will do the trick because you can place these lights within four inches of your seedlings. If they don’t get enough light, your seedlings will start to grow taller and skinnier, which is a problem because they need strong stems to grow during the vegetative stage. 5 – Helping your Headband crop grow strong during the vegetative stage. You can’t expect to have a strong flowering phase if the crop doesn’t have a good vegetative growing phase. As a grower, your role is to ensure your plants have healthy foliage, a robust structure to cope with heavy buds, and a strong root system. As your plants get bigger, they will need more nutrients and water. Since Headband comes with OG-lineage, you need to stay on top of your plants’ feeding schedule . Keep an eye out for curling or yellowing in the leaves, as this is a sign of dehydration or possibly a nutrient deficiency. Most growers like to use metal halide lamps at this point. You can keep your plants exposed to light 24 hours a day if you wish, but the 18 hours light, 6 hours dark schedule still works. Keep the growing room’s temperature between 68 and 78 degrees, although the roots’ temperature should be 65 degrees. Humidity is another vital consideration – keep it between 50% and 70% during the vegetative stage. Don’t be afraid to pile on the Nitrogen, but be wary of overdoing it. We believe it is folly to purchase regular seeds, because there is a 50% chance you will end up with a male plant. If you mix male and female plants, the males will pollinate the females and ruin your crop. Remember, only female plants will produce the fat buds that contain the cannabinoids to get you high. If you purchase feminized seeds or clones from a female plant, you don’t have to worry about male plants. However, if you try to save money by purchasing regular seeds, every second one will be a male plant. There are two widely used methods to determine gender.
The first involves examination of the fifth series of leaves on the plant. Make sure you perform the check right before the plant flowers. As Headband is a hybrid with indica genetics, it will display its sex between the leaves of the plant before flowering. When you focus on the right area on the plant closely, you need to look out for a tiny white fiber, as this shows you have a female plant. Although it is a quick method, it isn’t completely reliable, because trying to spot the small developed sex organs on a plant is tricky.
A better method involves taking cuttings of your plants while they are in the vegetative stage. Root these cuttings in a separate room and expose them to 12 hours of light and 12 hours of darkness per day.
