Critical Kush seeds are a perfect blend of Critical Mass and OG Kush. Barney's Farm originally bred the resulting authoritative Indica cannabis strain. Critical Kush Feminized seeds are a global sensation and listed as one of the best top 10 Indica strains.

With several techniques to germinate cannabis seeds, Premium Cultivars recommend the paper towel method to germinate your Critical Kush seeds. Not only is the process effective, but you can also easily source the materials needed. Below are the guiding steps for the paper towel method.

  1. Assemble everything you need for the process. That includes Critical Kush seeds, paper towels, bottled or purified water, two plates, and a pair of tweezers.
  2. Wet two paper towels and carefully drain the excess water
  3. Place one paper towel onto a plate and reserve the other for later use
  4. Place your Critical Kush seeds on the paper towel, ensuring an inch distance between each seed.
  5. Use the other damp paper towel to cover the seeds and add water if necessary.
  6. Check the plate's surface for excess water and drain, if any.
  7. Place a second plate over the first one and store the dish in a dark, warm place like a cupboard for 72 hours.
  8. The seeds should not dry out, so regularly check on them and add water if necessary.
  9. Once the seeds sprout, pick them carefully using a pair of tweezers and transfer them to a growing medium.

Feminized seeds are gender-specific, meaning your seeds will only grow into female plants you desire. The best explanation when comparing feminized and regular seeds is that there is no possibility of male plants pollinating female plants. Besides eliminating the need to separate make from female plants, feminized seeds also have reliable and consistent genetics. They have a 99% chance of blooming, so you are sure that your seeds will grow into cannabis plants. Feminized seeds are also available in a vast selection, meaning you can choose the strain.

These cannabis seeds germinate for seven days and take nine to 10 weeks before flowering. The growing duration of Critical Kush seeds from planting to harvesting takes about 10-12 weeks. However, the growth period can be affected by external factors. Humid conditions and temperatures of about 72-80 degrees are conditions for growing your Critical Kush seeds outdoors. Keep the buds away from the rain when growing Critical Kush seeds outside.

These seeds grow well in a temperate or hot climate of around 70 to 80 degrees Fahrenheit. Relative humidity of approximately 65% and 80% is favorable for the seedlings to thrive. However, you may need to lower the relative humidity to around 55%-70% during the vegetative stage. As your Critical Kush seeds bloom, improve airflow to avoid bud rot. Ensure your plants are well spaced and prune the branches to create room for buds to fill in.

You also want to water your plants every one to three days, so they do not wither. Growers can cultivate Critical Kush seeds in the soil or hydroponically.

How Difficult is it to Grow Critical Kush Feminized Seeds?

Are Critical Kush Feminized Seeds Suitable Seeds Suitable for Beginners?

Growers require some gardening skills to grow Critical Kush Feminized seeds. Experts and newbie growers can successfully cultivate these cannabis seeds.

Topping

Topping is a growing technique that involves cutting off the top of your Critical Kush plant so that it develops thicker and fuller. Your plants need to grow, so cutting them may seem like a crazy idea, but it is a proven method. Instead of growing tall and skinny, your plant grows bushier, resulting in better yields.

Low-stress training

For this technique, you bend the stems of your cannabis plants to use the available space. Low-stress training ensures your cannabis plants grow in the right direction and can help you boost yields.

Sea of green

The sea of green is a method whereby gardeners grow small cannabis plants close together to limit their growth space. You can use the sea of green technique when you have limited indoor space to cultivate your Critical Kush Feminized seeds.

Cannabis seeds related to Critical Kush seeds include Chocolope Feminized, Black Jack Feminized, Bubba Kush Feminized, and Cheese Feminized.
