How to Optimize the Growth rate of Your Plant

To optimize the growth rate of your plants, you need to do the following: 

  • Choose fast-flowering weed strain: Marijuana with a short flowering period means that you will have more harvest in a year.
  • Select soil with optimal balance between nutrients and pH: Marijuana plants require a balance in pH and nutrients to grow into healthy plants. With rich fertile soil, you can cultivate your marijuana plant using the organic method. Besides, organic cultivation helps minimize the impact on the surrounding environment.
  • Choose to grow lights that provide full spectrum: Grow lights such as LEDs, HIDs and fluorescents can provide the full spectrum that matches the one provided by natural sunlight. The light watts that you will use will depend on the marijuana strain you’ve planted. Indica strains, for example, need less light spectrum compared to Sativa strains.
  • Purchase feminized seeds.: Failure to spot a male plant in your garden could end up ruining your harvest. Feminized marijuana seeds are cross-bred to grow into high-yielding female marijuana plants.
  • Apply the training techniques: Low-Stress training techniques and the Sea of Green can be vital to boost your cannabis yields and save you some money in the end. 
  • Provide your marijuana plants with the essential nutrients:  Soil nutrients often get depleted. When this happens, you can use fertilizers to boost the soil’s nutrients. Fertilizers contain ingredients that are important for the growth of cannabis plants. 

These include Phosphorus, Potassium, Calcium, Magnesium, Nitrogen, copper, and Iron. However, you should apply the fertilizers in minimal amounts to avoid burning the cannabis roots.

Providing your plants with the right nutrients will ensure that you get high-quality yields of high potency. If you use soil as your growth medium, supplement it with these macronutrients. On the other hand, you do not need to supplement organic soils since they already have nutrients in the right amount. 

  • Develop a habit of monitoring your marijuana plants: Having a self-monitoring habit is essential. You can adjust the growing conditions and save yourself some extra coins. Also, you can spot male marijuana plants and remove them before they reach maturity. Cannabis plants need a different light spectrum during the growth, vegetative and flowering stages. 

During the vegetative stage, expose the plant to sunlight for about 16-20 hours daily. When they reach the flowering stage, expose the plants to 12 hours of light and 12 hours of darkness. Also, you can use a pH meter to check the soil and water quality from time to time. 

  • Control the temperature of your grow garden: To maintain the temperature, you can use different heat signatures. Fluorescent lamps are known to produce much more heat compared to Light Emitting diodes. You may also decide to use heaters or Acs to maintain the overall temperature in the grow room.

    Lastly, exposing your plants to healthy air circulation can help get rid of the warm and exhausted air. Doing this will bring about a cooling effect in the process.
  • Familiarize yourself with the harvest time: Knowing when to harvest your products can help you maximize your harvest.
