Plant lighting to replicate the sun

Plant lighting to replicate the sun


From eco friendly low power CFL (Compact Fluorescent Lighting) and powerful high output, low wattage LEDs (Light Emitting Diodes) to inexpensive high wattage HPS (High Pressure Sodium) including the latest digital CMH (Ceramic Metal Halide) lamps, you will find all you need to fill your lighting requirements at Bill & Bens HydroWorld’s Web Store.

Plants grown indoors require a broad spectrum of light!  The impact of light on plants goes far beyond just growth via photosynthesis.  Specific wavelengths of light are capable of manipulating the colour of leaves, plant shape, root growth, and chemical composition including the timing of flowering production as well as enticing pests out of crops and stopping disease.  As growers the most important spectrums of light we need are both the blue spectrum, which simulates the blue light of the spring for vegetative growth and then red, the light of summer, as this will help with fruit and flower development.

This can be achieved by using two separate lamps! A MH (Metal Halide) for the vegetative stage or a HPS for the blooming cycle of the plants life or you could purchase a Dual Arc (Dual Spectrum Lamp) that provides both spectrums and can be used throughout the plant’s life cycle & can save you money by only having to buy a single lamp .  When considering how to best use your lamps to produce the best crop you should also consider the other factors that affect your productivity ie; What’s the true PAR (Photosynthetic Active Radiation, dont worry its not the bad radiation we are talking about) of the light source you are using?  Remember Lumens are for humans & PAR is for plants!  

You will also need to consider the efficiency of the unit you are using and how much it will cost.  Say a traditional 600w HPS Lamp run by a traditional electrical Magnetic Ballast may cost you £10 per week to run depending on your providers tariff.   Plus you need to change that lamp every 6 months, so its cost you on average £480 on electricity and £50 per year on lamps that equals £530 per year.  When in comparison if you purchase a LED Fixture it would cost you an average of £300 per year to run without having to change the lamp.  Most LEDs have a lifespan of 5-10 years saving you between £1150-£2300 in electricity & £250-£500 in Lamps (Average Electricity = £1725 and £375 saved in lamps) compared to an HPS lamp.  When you look at it like this even the top high spec LEDs would have paid for itself via the savings you have made.
