Air pressure and fan control

Adequate ventilation in your grow room is vital. If you don’t provide ventilation to keep air moving in and out of your grow room you can find that temperature, humidity and C0levels are too high. HID lights produce a lot of heat, so if you are using these it is crucial that you have sufficient ventilation to reduce the grow room temperature.

Signs you do not have enough air movement in your grow room can include mould, mildew and high humidity; all indicate the need to take action. Read on to find out more about how to maintain the perfect grow room environment.



Why we’re Coco about 60/40

There’s no doubt about it, we are a nation of coco lovers. But what if we are missing a trick? What if we could have all the benefits of coco… And more!

Gold Label 60/40 is a perfect mix of 40% premium RHP certified Coco and 60% mixed shape clay pebbles. This careful balance protects against drying out, oxygen starvation, clumping and compacting. Providing a top-quality rooting environment.



Maintaining the perfect pH level

The perfect pH level changes depending on what you are growing in and of course what you are growing. We recommend a pH level between 5.8 and 6.5.

Check pH levels of your nutrient solution in your tank weekly. You can use an approved test kit e.g, Nutriculture liquid pH test kit or an easier and more precise result can be achieved by choosing a digital pH meter like the HM Digital PH-200 and PH-80

If the pH of the solution is in the correct range 5.8 – 6.5 you needn’t do a thing.

If the pH of the solution is above the correct range add phosphoric acid (pH Down).

If the pH is below the correct range add potassium hydroxide (pH Up).



Indoor Gardening - A beginners Guide


Growing environment is so important to successful growing. The five main factors to maintain are:

  1. Temperature – The ideal grow room temperature is between 26-28 degrees. You must remember that fluctuations in temperature will affect your humidity levels
  2. Humidity – Most plants with thrive with humidity between 40-60%. Some do like higher humidity but you must be aware that high humidity increases the risk of disease and fungus.
  3. CO2 level – Plants need CO2 in order to grow. CO2 will naturally be around 300-400 PPM, you can however supplement CO2.

Light spectrum and measurement explained


Natural sunlight consists of a wide spectrum of colours, although it may look orange/yellow/red to the human eye, the sun actually produces a much larger spectrum of light, including blue, green and purple. These become visible when a rainbow is present. Plants make use of a range of colours present in the spectrum. This broad spectrum of colour can also be separated by wavelength, which is measured in nanometers.

Why choose Rhino carbon filters?

Pelletized carbon is created by burning coal and processing it into rods which are broken up and distributed throughout the filter. The problem with palletized carbon is that is has very small pores due to the bonding agents used in the manufacturing process which cause pore structure to collapse. This makes pelletized carbon filters less effective at absorbing odour, and so will not rid grow rooms of odour.

Plants need oxygen too!

A lot of people forget that Oxygen is one of the most vital nutrients a plant requires - plant roots need oxygen for aerobic respiration, this is a necessary process that aids roots in taking up nutrients.

One of the first signs of low oxygen levels in a plant is wilting under warm or bright conditions. Insufficient oxygen availability for plants will reduce their ability to absorb nutrients and water.
