Hemp indicates the liquid substance of Cannabis that doesn’t have enough THC, so it won’t get you high. It is one of the oldest cultivated crops on Earth. They have a long record of using products from materials to food, cosmetics, and textiles.
The American hemp industry is growing, and manufacturers hope to get their hemp locally instead of importing them from Canada and Europe. Hence, hemp farming is being encouraged. The USDA doesn’t permit marijuana to be licensed organic in the US, officially produced. Nevertheless, the agency has made an exception for hemp. The market for certified hemp seeds is vast.
Cannabis plants and products that contain THC lesser than 0.3 are classified legally and commercially as hemp. Knowing the THC levels in the types, range, or cross you plan to grow.
Let’s get down to the basics.
Male & Female Plants
The cannabis species are dioecious – both the male and female flowers mature on individual plants. Most growers produce hemp from the seeds. So, when you germinate hemp seed, know that almost half of the plants will be male and half female.
These feminized seeds are meant to produce nothing but female plants. However, feminized seeds can be bought, which are made by activating female plants to produce pollen sacs with only female genetics for self or cross-pollination. You can also breed vegetative replicas of your plant by taking plant extracts.
A few things to take into consideration:
- To produce hemp flowers, one only needs to grow female plants that stay unfertilized.
- You can collect hemp fibers from male and female plants.
- Female plants that are pollinated produce seeds (grain).
It is easy for cannabis plants to produce male and female flowers – these plants are known as hermaphrodites. They are caused by the genetics of the plant and environmental stressors. To reduce this, ensure the plants are loved and not exposed to ecological pressure during blossoming.
Cannabis sativa is a photoperiodic plant with both phases: flowering and vegetative. It requires different darkness (night) and daylight (day) phases. Hemp plants blossom when the dark (night) period is extended to 12 hours.
But when the dark (night) period is briefer than 12 hours and the light (day) period is lengthier, plants do not flower and stay vegetative. A closed growing environment such as a blackout cover or cultivate tent allows you to control photoperiod.
Growing Hemp Indoors
The advantage of growing hemp indoors in a well-measured environment is that you’re making use of artificial light, and that lets you achieve plant development and flowering better.
Bugs, rodents, and even birds can attack hemp outdoors, and depending upon the extraction and refinement process, outdoor-grown hemp might not even be safe for human consumption.
Hemp plants have four distinctive growth stages that are:
Germinating indoor hemp seeds is the same as growing other plants from seeds. You have to use a similar method and environmental circumstances for it.
- Pre-soak the seeds for a max of 12 hours to increase germination
- The ideal temperature for germination is 65-70 degrees
- Plant your seeds one inch deep in a seed starting mix
- Use a thermostat to manage soil temperature control better
- Make use of a humidity dome to achieve germination humidity
Care For Hemp Seedlings
Temperature: Seeds that are germinated need a temperature between 68-77 degrees Fahrenheit. You can use a heat mat to check the seedling temperature.
Humidity: The best humidity range is 65-70%. It is best to keep the humidity dome on top of the seedlings in the initial two weeks. This protocol will allow managing the humidity levels better.
Light volume: The seeds need proper light once germinated – to supply that, you can use high-output LEDs or T5 fluorescent grow lamps and place them right above the seeds.
Light photoperiod: It is best to have the grow lights on for a minimum of 18 to a maximum of 24 hours a day. If you feel the seedlings are stretching, you can lower the lamps nearer to the plants and time how much light they consume.
Feed: It is best to use a nitrogen-rich fertilizer that is water-soluble.
Note: All fertilizers have different ratios – choose the one similar to the balance you want.
It’s time to transplant the hemp seedlings:
First transplant: When the seedlings have embedded into the base and sides, transplant them into a 4-to-5 inch pot using a transplant mix.
Final transplant: When the seedlings have embedded into the base and sides of the 4-to-5 inch pots, it is time to transplant them into a final container that is much bigger or a fabric grow bag while using a marginally denser compost-based potting mix.
The Bottom Line
As you can see now, growing a hemp plant indoors is a process that requires time, effort, and money. Even though it seems like a great alternative to buying hemp flowers, that isn’t safe. Nevertheless, many farmers have learned to grow these plants all over the country.
To successfully grow hemp will take you some trial and error. But, it’s just the same as any new plant development task you undertake. Try experimenting with a few plants on your first try and follow these basic beginner steps.
