What is (are)… Phosphorous and Potassium

Phosphorus is the 15th element on the periodic table with the symbol ‘P’. Due to its high reactivity Phosphorus is never found as a free element because it is highly reactive.

Relative Humidity

Relative Humidity

In this cold wintery weather, our relative humidity (RH) drops drastically. Knowing your RH is essential for healthy plants during vegetative growth and flowering.

In vegetative growth plants require higher levels (>70%) of humidity to flourish and reach their potential. This is achieved in a number of ways;

1) Make sure plants are grouped close together to create a microclimate.
2) Any oscillating or clip fans that are on need to be off, this applies for air in as well. These remove any humidity you may be achieving.
3) A wet towel or bucket of water may help in raising humidity levels.
4) Domes...

Demystifying Lumens, Lux and PAR

LED lights require new thinking about the way we measure light for use by plants. The typical rating most growers are familiar with is the “lumen.” The definition of the lumen is the total light produced within the range of the human visual response. It tells us nothing about the distribution of that light energy over the spectrum, and most importantly, it doesn’t tell us how much is useful for plants.

The problem with lumens is especially pronounced when measuring light...

Grow it yourself: chilli pepper

Did you know that Europeans only came into contact with the chilli pepper after Columbus discovered America? Since then, over 3,000 registered species have been developed. Of these, five are widely cultivated: Capsicum annum,Capsicum chinense, Capsicum baccatum, Capsicum frutescens and Capsicumpubescens. All have their own special characteristics. 

Capsicum annum: Annuum means annual, but strictly speaking this is incorrect since under the right conditions, these chilli plants can be kept for years. This variety of chilli is the easiest to grow. Most common chillies belong to this variety:

Bell Pepper (paprika),
jalapeño, cayenne pepper, Serrano and all 'waxed'...

When should you use hydroponics?

There are many different types of soil that you can choose from as you begin to design your garden. The amount of space you have set aside to grow your plants is an important factor in deciding which soil to go with. If you have a limited amount of land on which to plant, then hydroponics may just be for you.

The unique thing about hydroponics is that it only requires water to grow plants - no soil is needed. Soil-less gardening delivers the nutrients needed by plants to grow in a more direct manner than...
