CA-Fortify Cal-Mag fertiliser is used to prevent calcium deficiencies for fast growing crops. If you are growing calcium-hungry cultivars in coco or potting soil, Fortify is the solution. Best used in conjunction with both Beanstalk Absolute Flower and Beanstalk K-Boost.

The Sustainable Solution

At Ecothrive, we are often asked "what's the best mineral fertilisers to use with your coco coir mixes?". We now have an answer; Beanstalk CRF is arguably the most environmentally sound option for complete mineral fertility, while producing high yielding crops with minimal fuss.

While Beanstalk's CRF technology is not organic it does eliminate many environmental issues associated with conventional mineral fertilisers. The advanced polymer coating effectively controls nutrient release and prevents the fertiliser rapidly dissolving in the growing medium, reducing leaching and waterway pollution.

When growing with Beanstalk CRF, minimal run-off is required. When using liquid nutrients, growers typically aim for 10-20% run-off at each watering event, with Beanstalk you can cut this down to 5-10% run-off once a week! Using Beanstalk ensures efficient water usage and stops your fertiliser (and money) going down the drain.

One dose of Beanstalk Ag Controlled-Release Fertilizer (CRF) automatically and intelligently matches the nutrient requirements of your plants throughout their growing cycle.

No bottles. No powders. No mixing reservoirs. Simply blend the CRF into the growing medium when transplanting. Improve your efficiency, cut costs, simplify your grow and boost yields today!

What does CA-Fortify do?

Attention all coco growers! Designed for a 100-day release rate, this single-application, calcium/magnesium-fortifying additive is the plug-and-play product you have been searching for.

If you are using peat-free or coco substrate, Nitrogen draw-down can be an issue. The slow release N from CA-Fortify ensures Nitrogen is continually available to your plants throughout.

Simply mix into your growing medium when potting up and Beanstalk’s controlled release fertiliser will provide your crop with all the necessary minerals, micro and macronutrients that they need for maximum growth and yield.

With the Beanstalk program you can use growth stimulants, beneficial biological inoculants, and other additives such as silica. Just avoid using nutritional products.

For best results, use in conjunction with Beanstalk Absolute Flower and Beanstalk K-Boost.

How to Use

To get the best from Beanstalk CRF products just follow these simple steps:

  1. Fill the pot 2/3 or 3/4 with your chosen growing media, coco or potting soil.
  2. Add the relevant dose of Beanstalk products.
  3. Mix thoroughly.
  4. Pot up the plant, then top up the remaining 1/3 or 1/4 with coco or soil.
  5. Irrigate with water and, optionally, your preferred silica and non-NPK additives.

Ecothrive coco mixes are all pre-fertilised with a light dose of Charge. This provides enough nutrition to last until the CRF starts releasing, which takes approximately 7 days after the first irrigation. For best results, use Biosys on your first watering and repeat every 1-2 weeks.
