Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10-14 weeks. Great for new growers, small spaces, and multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Flowertime Fertilizer

Bergman's Flowertime Fertilizer contains a very high potassium concentration. Its high levels of nitrogen encourage foliage growth.

Plant Booster

Bergman's Plant Booster is a flowering stimulator filled with nutritional power. Add it to your plants during their last stages of the vegetative phase to induce early flowering.

Heavier yields and increased quality should be expected.

Marijuana Fertilizer Storage

Bergman's Plant Food Fertilizers is delivered in securely packed and sealed airtight bags. This makes it easy to store your nutrients. As long as the fertilizer is kept dry, you can store it for long periods of time. To be on the safe side, we advise using the nutrients within 12 months after opening the packs.

Marijuana Fertilizer Usage

Bergman's Plant Food is designed for correcting plant deficiencies and enhancing growing mediums. For best results, check for deficiency before using this marijuana fertilizer. Be advised, many growing problems are resolved by the proper amount of sunlight and water.

Always test your pH before adding Bergman's Plant Food. The ideal pH is between 6.0 and 7.0. Marijuana plants with poor pH cannot absorb nutrients and will impact your results.

Never give your plants more than they need. Overfeeding can lead to nutrient burn, which can harm your plants. For optimal flavor, flush your plants approximately two weeks before harvesting.

The nutritional needs of marijuana plants change as they mature; therefore, you must use a marijuana fertilizer that is appropriate for their development. View the feeding schedules below for usage guidelines.

Always take your personal situation into account and apply nutrients accordingly.

  • Dissolve the indicated grams of nutrient powder in 1 liter (0,26 gallons) of room temperature tap water (20ºC / 68ºF)
  • Stir well and adjust to the optimum pH value if needed
  • Use in combination with the other Bergman's Plant Food fertilizers for optimal results
