Light, Lumens, Lux and Par
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 at the far ends of the human visual response curve. Consider three lamps—red, green...
Grow it yourself: chilli pepper
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' peppers. The...
What is hydroponics?
What is hydroponics? If you've ever placed a plant clipping into a glass of water in the hopes that it will develop roots, you've practiced in a form of hydroponics. Hydroponics is a branch of agriculture where plants are grown without the use of soil. The nutrients that the plants normally derive from the soil are simply dissolved into water instead, and depending on the type of hydroponic system used, the plant's roots are suspended in, flooded with or misted with the nutrient solution so that the plant can derive the elements it needs for growth. The term hydroponics originates from...
