Horticultural Lights:
These lights are professional horticultural lights. They are developed by horticultural lighting companies and are tested to suit growing plants indoors. These lights are commonly called HID (High Intensity Discharge). Like the former lights these also come in kits with bulb, reflector, ballast and timer. They also come in different wattage and different shapes and sizes. If you want to grow good bud then you need a HID. A HID is the second most important purchase you will make next to choosing your strain.

Metal Halide (MH) and Mercury Vapour (MV):
The lights are HID lights and are used for the seedling and vegetative growth stages of your plant. They can also be used for flowering and are quite good too. They come in all shapes and sizes and range from 75W – 4000watts. These lights are very common and are a good kit for the indoor Cannabis grower.

Mercury Vapour is not as common as it used to be. It has almost been replaced by Metal Halide now. If you have a choice between the two it is best to stay with the new MH kits. MV also has a tendency to be slightly out of the optimal spectrum range.

High Pressure Sodium (HPS):
This is the lighting choice of many a Cannabis Cultivator. These lights come in all shapes and sizes and have a range of 75watts – 4000watts. These lights are in the perfect spectrum for growing cannabis and come highly recommended.

    Bought your latest book. Lot’s of good data, but light info is confusing for us brain dead types. Can you please let me know which company is the best on the web to buy 1000 watt kits from, and more specifically which 1000watt kit to buy. If you need to stay neutral, then please give my email address to someone able to be specific. Thanks Eric
