Scrog Net - Screen of Green R 15.00 R 30.00
Horticultural Netting, commonly known as SCROG (Screen of Green) netting, is a durable and rigid product made out of polypropylene, specifically designed for the structural support of horizontal and vertical growth. Whether used vertically to provide support for climber crops or horizontally to maintain an even canopy, the uses and applications for horticultural netting goes far and wide. It is 1.4 meters wide and is sold per metre. In vertical horticulture the netting is typically installed 30cm above the grow medium. For crops that grow very tall, you can run strips measuring 1.4m wide and as high as needed. For crops that don't grow as tall but still grow vertically, you can run strips 1.4m high and as wide as needed. In horizontal horticulture an initial layer of Scrog is installed horizontally over your crops with as many additional layers above that as needed. A net fastening structure is usually constructed so that the netting can be tightly stretched over your crop allowing the grower the ability to support, train and manipulate growth into an even canopy. Advantages of using horticultural netting: Increases plant density by expanding the growth surface along the netting. Increased sun exposure. Increased aeration within the garden. Protection of flowers and fruits through structural support. Less chances of mold and fungus growth. Increase in number of flowers and fruits harvested. Decreased chances of accidental damage to fruits and flowers. Extends the life span and general health of plants. Carefully designed to not cut or hurt plants in any way.

Cal - Mag - Calcium Magnesium Supplement R 60.00 R 72.00
Cal-Mag is a specially designed nutrient to compensate for deficiencies. Calcium and Magnesium (referred to as Cal Mag for plants ) is almost always needed when using pure, distilled, or reverse osmosis water. Tap water almost always has an abundance of Calcium and Magnesium in it. Calcium and Magnesium are the most abundant minerals in tap water. The majority of the PPM, or EC reading, you obtain from a measuring device is Cal-Mag. Available size: 1kgCalcium, an essential part of the plant’s cell wall structure, improves the absorption of other nutrients by the roots and their translocation within the plant. It activates a number of plant growth-regulating enzyme systems, helps convert nitrate-nitrogen into forms needed for protein formation and contributes to improved disease resistance.Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify or break down compounds as part of a plant’s normal metabolism. Recommended Cal Mag dosage: 150 PPM / 0.3 E.C per 10L Nutrient content in our Cal-Mag supplement: N 134.8 g/kg NH4-N 9.1 g/kg NO3-N 125.7 g/kg Urea-N 0.0 g/kg P 0.0 g/kg K 0.0 g/kg S 0.0 g/kg Ca 115.3 g/kg Mg 36.4 g/kg Fe 248 mg/kg Mn 131 mg/kg Zn 83 mg/kg Cu 15.5 mg/kg B 80 mg/kg Mo 13 mg/kg
5cm Net Pot R 0.75
5cm Net Pots offer huge flexibility in many different types of hydroponic setups and DIY projects. They are mostly used in NFT systems, Aeroponics and Bubble Cloners. The slits allow the grower to use a wide variety of growing mediums. The smaller 5cm Net Pot is best suited to plants that have a naturally smaller, slower developing root structure. Inexpensive. Reusable. Built to last. Perfect for seedlings and propagating cuttings. The slits provide excellent air flow to the root zone and great irrigation. Size: 5.5cm x 5.5cm x 5.1cm How to get started: Propagate a seed in a Peat Pellet or Rockwool Starter Plug. Alternatively, you can use a already propagated seedling bought from a nursery, just be sure to gently wash all of the medium off of the roots before placing it in your Net Pot. Once the roots start to grow through the bottom of your propagation medium you can place your seedling in the middle of the Net Pot and fill around the roots with Expanded Clay Pebbles or any other grow medium of your choice. If you are using a smaller sized Net Pot you may find that the propagated seedling will fit snugly into the pot without you needing to secure it with any medium. At this point the propagated seedling in it's Net Pot is ready to be transferred into your hydroponic system. However, if you are using the Nutrient Film Technique you may need to top feed for a week or so until the roots have grown towards the water source.

Mycoroot Supreme R 55.00 R 80.00
Premium Mycorrhizal, Mycoroot, is the home of the organic mycorrhizal fungus. Mycoroot Supreme is an organic microbial fertilizer that will help enhance root structure by doubling it in size, boosts yield, and production.   What are Mycorrhizal Fungi? Mycorrhiza means “fungus root.” These are beneficial fungi found in undisturbed soils These fungi form a symbiotic, mutually beneficial relationship with 90% of all plant roots The host plant receives mineral nutrients from the fungus The fungus obtains sugars from the host plant There are several types of mycorrhizal associations The most commonly encountered are the arbuscular mycorrhizal (AM) fungi.   How do they function? The fungus grows using fungal filaments called hyphae The filaments grow both inside and outside of the roots The fungus is intimately associated with the plant roots Providing a link between the soil and the plant They extend the plant rooting system improving root functions They allow for better exploitation of the soil environment They increase the surface area available for nutrient uptake They make nutrients soluble which usually are not accessible to plant roots They influence the soil environment covered by the fungal filaments Encouraging the growth of beneficial bacteria They ward off unwanted organisms which can cause plants diseases Such as eelworms and root rot They produce a biological glue That promotes soil stability and increases moisture penetration and aeration of the soil Characteristic AM fungal structures formed within the roots of a host plant. Characteristic AM fungal structures formed within the roots of a host plant. A = finely branched arbuscules formed within plant cells. V = vesicle produced by some AM fungi required for the storage of carbon compounds. IRH = intraradical hyphae grow between the root cells. These structures are only visible once the roots have been specially prepared in the Mycoroot laboratory and are visible under a high powered microscope.   So what is the problem? Unfortunately, because the soil and the beneficial organisms in this environment will not be regarded as a valuable resource, disturbance, land degradation, and application of chemical inputs, particularly those containing high levels of phosphates, and the non-discriminate use of some pesticides, have resulted in depleted natural populations. So what is the solution? To maximize the benefits from these AM fungi, have the mycorrhizal status of your soil tested.   How to use: Mycoroot is used during transplanting. It helps with plant growth, health, and flowering. Add 5-10ml (1-2 teaspoons) per transplant depending on the size of the plant. Sprinkle at the base of the plant's roots in the whole during transplant and this should stop the shock of transplant, also helps with the uptake of nutrients and water.   Size of container: 200ml
