Product Description

GrowSure: Multi-purpose Starting Mix and Soil Enhancement

GrowSure is 100% Coco Pith, (a by-product from Coco Husks used in Coco Coir industry) that is perfect for all types of soil-less growing, including large and small scale hydroponics.

GrowSure is frequently used for seed and propagation starts in commercial greenhouses, as it is the HortGrow product with the highest in moisture and nutrient retention.  GrowSure Coco is best suited for smaller volume or shallow containers and short-duration crops like lettuce, spinach, chard and radishes, as well as soil conditioner to enhance moisture retention and aeration.

Perfect for Seed Germination, Plant Propagation and Young Transplants :

  • Improves aeration and drainage when mixed with other potting media
  • Fine milled Coco Pith, with an even, fluffy texture and neutral scent
  • Triple washed and sun dried to assure low EC (electrical conductivity) and optimum pH
  •   Warranted free from microbes and pathogens; soil and weed free
  • Free from excess salts and other non-essential matter
  • Absorbs 30% more water than peat moss and is easier to re-wet when dry
  • Proven preferable for hydroponic use as it maintains optimum capillary health

GrowSure is available in easy to use blocks, (sold individually on Amazon or delivered ready to hydrate to the grow site), compressed discs, or in a variety of grow bag configurations for hydroponic application.

The blocks can be placed in a container or wheelbarrow and rehydrated. Often the blocks are placed in the container garden area and rehydrated where they will be used, requiring no shoveling or scooping from an unwieldy bag.

When hydrated, the Coco Peat is virtually odorless, has a fluffy consistency. Unlike peat moss, which can be difficult to re-hydrate once it is dry, Coco Pith is like a conventional sponge: when it is exposed to water, it is immediately absorptive, making
moisture and nutrients readily available to the plants.

HortGrow professional hydroculture experts are available for consultation and all GrowSure Coco Peat grow bags (closed, open top and layered) and grow trays are customizable to our customers’ specifications. Call or click here to request more information

GrowMax: Multi-purpose Growing Mix and Soil Enhancement

GrowMax is optimized for moisture, air porosity and drainage, and is ideal for medium to large volume containers. This is perfect for patio pots with bedding plants are placed for seasonal color as it extends the blooming and bearing time for flowers and herbs.

GrowMax is the best soil-less growing media for long-duration crops, like cucumbers, kale, beets, beans, squash and long-blooming flowers like petunias, Transvaal daisies, gerbera daisies, and seasonal bulbs. GrowMax is available in a layered media compressed disc as well as a convenient block.

This blend is well-suited for seed germination, plant propagation and medium-term container crops:

  • Improves aeration and drainage when mixed with other potting mediums
  • Can be used alone as the potting medium; no other soil or additives needed
  • Liquid nutrient(fertilizer) added to water to ensure even plant growth
  • Quadruple- washed and sun dried to assure low EC and optimum pH
  • Warranted free from microbes and pathogens; soil and weed free
  • Free from excess salts and other non-essential matter
  • Absorbs 30% more water than peat moss and is easier to re-wet when dry
  • Proven preferable for hydroponic use as it maintains optimum capillary health

GrowMax is available in easy to use blocks, (sold individually on Amazon or shipped ready-to-hydrate on pallets delivered to grow site), grow discs, or in a variety of grow bag configurations for hydroponic application.

A single 5 kilo block when hydrated will fluff up to become the equivalent of a bulky 2.5 cu.ft. bag of peat moss.  The block arrives in an easy to carry tote bag, and the block can be hydrated in place—no scooping or shoveling—or hydrated in a wheelbarrow. It is best to drizzle water a little at a time to let the Coco Pith “sponge” soak it up; it will not speed up the process if you add water faster than it can be absorbed. The entire hydration procedure takes just a few minutes from beginning to end, and produces a planting medium that is moist and surprisingly easy to use.

Home Gardeners can “grow like the pros” when they buy GrowUltra Coco Peat blocks on Amazon. Each compressed block, (which weighs about the same as a large bag of groceries), is shipped to your doorstep in a sturdy tote. The Coco-block is easy to move into place on patio, garden or greenhouse where it is hydrated and converted to usable form.

GrowUltra is best placed on the ground, gardening cart, or a pot, before adding water a bit at a time.  It only takes seconds to bloom into a fluffy, resilient growth medium for large containers or grow bags. It can also be mixed with compost, worm castings, fertilizer or mixed into existing beds to improve water retention and aeration.

It is available in compressed discs, blocks and in bulk.

Hint:

  • A little GrowUltra Coco Peat goes a long way! It is easy to carefully hydrate the corners of a block and then split off the dry parts of each block and store the pieces in the sturdy GrowUltra carry bag for later use.
  • Once incorporated into the potting mix or garden, it is advisable to monitor watering cycles as containers and in-ground gardens that have the benefit of the sponge-like qualities of Coco Pith will require less-frequent watering, even in very arid climates.

GrowExcel: Staying Power for Long-Duration Crops

GrowExcel is the perfect medium for long-duration crops and sustainable decorative plants like potted palms and large indoor trees and blooming shrubs.

Many plants like hibiscus, sego palm, miniature roses and Texas sage are well supported in GrowExcel as well as dwarf pomegranates, dwarf citrus and other dwarf stone fruit, and long cycle berry (Rubus) crops like black berries, raspberries, and blueberries.

This blend is especially course in texture with long-lasting qualities:

  • Large chunks and shreds break down slowly
  • Maximum aeration supports mature plants
  • Perfect hydroponic mix for long-cycle crops
  • Balanced blend of fine Coco pith, medium Coco fiber and Coco Shreds
  • Washed 4 times and sun dried to assure low EC and optimum pH
  • Slowly biodegradable and long lasting, reducing cost and labor
  • Maximum airspace and drainage while retaining soluble nutrients

This mixture is scientifically engineered to overcome the problems that arise with long-cycle growing, namely compaction and loss of aeration due to rapid break-down of the large components of the original potting mix.

The main three components of GrowExcel Provide Specific Benefits
Unlike wood chips and peat moss, the Coco Fiber and chunky Coco Shreds have at least a 5-year life span, providing their life-sustaining aeration to the root system of perennial plants. They maintain moisture and their irregular shape retards compaction.

The addition of fine-grained Coco Pith is equally important, as it also stands the test of time. Coco Pith has an amazing sponge-like quality. If it is wet and compressed, for instance, the excess water is easily squeezed out, but like a sponge, it will spring back in your hand…Still moist, but fluffy, not compressed and condensed. These qualities allow the fine pith to work into the areas around the chunky shreds, maintaining moisture around tender roots while helping to maintain constant aeration.

The fine Coco Fibers in the mix are very small conduits that draw moisture via osmosis from the wetter to the dryer areas. It is one of the natural wonders of Coco Coir that these fibers help aerate and stabilize moisture without rapid disintegration.

GrowExcel is available in convenient GrowExcel Blocks, (available on Amazon), Grow Slabs and bagged configurations, and is customizable to customer specifications in discs or slabs.
