Hy-Gen PK Top Up - 500ML 1L 5L 20L | Potassium & Phosphorous Booster
Regular price $20.00 Save $-20.00
PK TOP UP is formulated using high quality soluble ingredients and designed to supply additional levels of phosphorus, potassium
and trace elements levels during the flowering and fruiting stage. Potassium and phosphorous help improve flower and fruit colour as well as enhance the flavour of the final product. PK TOP UP’s highly concentrated formula means you only need a small dose to achieve fantastic results.
During early flowering and fruit set, plants absorb higher levels of phosphorous and potassium. As levels fall, the growth and flowering rates can slow, leading to aborted flowers and fruit. When used regularly, PK TOP UP can be used to quickly correct deficiencies or simply to return phosphorus, potassium and trace elements back to optimal levels.
Continue using NITRO-K until there are visible signs of flowers and buds then start using PK TOP UP. This will ensure a continued supply of potassium for flowering while nitrogen is replaced by additional phosphorous needed for fruit production. Using the two products in succession will give improved colour, flavours and yields. The results will clearly be visible in the quality and yields of the final harvest.

Hy-Gen Humiboosta - 500ML 1L 5L 20L | Boost Health & Yield
Regular price $80.00 Save $-80.00
HUMIBOOSTA™ is formulated using a blend of Humic and Fulvic acids to improve nutrient solubility thus enabling maximum nutrient availability. They are selected and derived from various natural deposits and processed sources. Additional macro nutrient forms of these organic acids ensure that background nutrient levels are replenished throughout all stages of plant development. The list of nutrients include calcium, magnesium and potassium.
HUMIBOOSTA™ assists in maintaining health in the rhizosphere while encouraging beneficial microbes, especially when cultivating in cocopeat, soil and hydroponic systems. Humic and Fulvic acid are known for their ability to bind to nutrients, making them more absorbable. HUMIBOOSTA is suitable for all systems and can be used through all stages of plant growth and flower and fruit development.
HUMIBOOSTA™ is also a source of additional magnesium, which supports healthy vegetative growth. Magnesium plays a key role in photosynthesis since it is an essential building block for chlorophyll production during photosynthesis. Another benefit is the addition of soluble calcium, which is essential during the late growth stage to ensure a high number of flowers are produced and retained by the plant. The lack of calcium can lead to a large number of flowers aborting before they can transition into the fruiting stage.
Give your plants the boost they deserve from start to harvest – Boosted health gives boosted yields!

Hy-Gen Omegazyme - 500ML 1L 2L 5L 20L | Growth & Root Mass Enhancer
Regular price $40.00 Save $-40.00
OMEGAZYME is a blend of natural sea kelp selected specifically for their root and shoot promoting properties. The organic compounds are known to enhance and accelerate root repair and root system development. They are also known to actively promote vegetative growth and stimulate early flower production. The raw plant ingredients used are carefully prepared using a cold pressed method, which ensures the naturally high levels of these boosters remain strongly active.
OMEGAZYME contains natural organic bound, readily absorbable, trace elements, which also stimulate root repair and growth while promoting new vegetative growth. The ingredients in OMEGAZYME ultimately aid in the natural transport processes occurring within the plant rhizosphere. In a way it behaves as a tonic for the rhizosphere. The process helps resist stress brought on by drought, over watering, nutrient deficiency and root diseases.
It is excellent for use on new cuttings and effective on all plants and safe to use in aquaponic systems. It is also a great pre-conditioner or pre-soak for cocopeat. Continue using OMEGAZYME until flowers and buds form then commence using it with SEA ESSENTIALS until fruits begin to form. This will optimise the transition into fruit production and maximise yield potential.

Hy-Gen pH Complete Control Kit - 150ML pH Up & Down | pH Indicator Kit
Regular price $25.00 Save $-25.00
- In hydroponics "pH" is an extremely important factor. When it is poorly monitored or controlled, plants can become sick or die. It is therefore recommended that pH is tested daily. Hy-Gen pH Up and Hy-Gen pH Down provide the grower with an added control in maintaining optimum pH levels and hence maximizing nutrient availability and plant productivity. A too high or too low pH can complicate the absorption of important nutrients such as iron, calcium, magnesium, etc.
- Generally the pH of the hydroponic solution should be 6.3. It is acceptable, however, to maintain the pH in the range of 6.0 to 6.5. For rockwool a lower pH of 5.8 to 6.0 is recommended. This allows for optimum nutrient solubility and availability.
HY-GEN® COMPLETE pH KIT is an easy and accurate way to keep track of the nutrient solution pH. The kit gives the added ability to adjust your pH using the pH UP and pH DOWN solutions provided. Adjusting the pH is quite easy and after some time and experience it becomes an art as you start to learn more about your plants and growing system.
The concentrated indicator solution allows you to obtain a reading by using just one drop in the test tube provided. The calibrated colour chart provided helps test your pH to within 0.5 of a pH unit. Testing and adjusting your nutrient solution regularly will ensure your plants are healthy and happy.
Testing and adjusting the nutrient solution pH is made easy with a HY-GEN Complete pH Kit. The kit comes supplied with a test tube, 1mL transfer pipette, 150mL pH Up, 150mL pH Down, colour chart and concentrated indicator solution. Testing only requires one drop of indicator.

Hy-Gen EC Conductivity - 2.76 | 250ML / 500ML /1L | Calibration Solution for EC PPM Meter
Regular price $10.00 Save $-10.00
It is essential to calibrate your EC (electrical conductivity) meter with CONDUCTIVITY 2.76 solution regularly. The measurement of available nutrient in the solution is measured as the electrical conductivity. The units used to report the readings are millisiemens per centimetre (mS/cm), Conductivity Factor (cF) or parts per million (ppm).
The conductivity increases with nutrient strength. Distilled or deionised water will give a near zero reading. As a general guide for hydroponics: 1mS/cm = 10cF = 700ppm. Nutrient requirements vary from plant to plant; therefore the ideal conductivity varies from plant to plant also.
