What is in Charge?

Charge contains of just one ingredient: premium grade beetle frass. (Frass is the technical term for insect poop.) The specific insects that create Charge are the larvae of Tenebrio molitor beetles, commonly known as mealworms. Charge goes through a number of processes and tests before being packaged to ensure it’s of the highest quality and no actual insects are present.

What do the beetle larvae eat?


Good quality outputs come from good quality inputs! The beetle larvae that make Charge are treated to a diet of organic carrots and wheat bran. These components contain everything the beetles need for a healthy lifecycle. Additionally, this strict vegetarian additive-free diet ensures the mealworm frass is the same high quality each and every time to deliver a consistent product year round.

How Does Charge Work?

Charge improves plant growth in a number of ways. Firstly, Charge provides a range of macro and micro-nutrients needed for healthy plant growth. Secondly, mealworm frass is packed full of beneficial microorganisms. Laboratory tests have shown that Charge consistently contains more than 450 million colony forming units of beneficial rhizosphere bacteria per gram! These beneficial bacteria ‘charge’ the potting mix, making it more favourable for root growth and function, and vastly improve nutrient cycling and availability when growing organically. Finally, being an organic waste from insects, Charge contains derivatives of chitin, which is a modified polysaccharide found in large concentrations in the cell walls of insects. The chitinous derivatives found in Charge are able to naturally elevate the plants in-built resistance to pests and disease, as well as increase growth rates and productivity; ensuring a healthy and fruitful crop.

When Should I use Charge?

For best results, mix Charge into your potting mix before planting. If your growing media has a low-medium  nutritional content , such as Coco Coir or straight peat, mix it at 1-2% by volume (10-20ml per L). If you use a heavily fertilised potting soil mix it at 0.5-1% by volume (5-10ml per L). See below for more application info.

In the weeks after mixing into the growing media, water and feed as you would normally. Charge contains a mild kick of nutrients and will compliment your nutrient regime, not interfere with it.

For continued plant health and growth improvement, top dress Charge onto the surface of the growing media every 2-4 weeks.

Charge can also be mixed with water for use as growth boosting foliar spray. See below for more details
