Hps Mh Ballasts & Kits

HPS Grow Lights hps bulbsHPS bulbs are generally available from 150W up to 1000w sizes. The most common sizes used in indoor cultivation are the 250w, 400w and the 600w. This amounts to lumens between 100 and 150 lumens or so each watt, according towards the size of lamp. Their colour temperature is pretty low, between 2000K and 3000K; they emit a pinkish, golden white light which can be similar to autumn daylight. Remember tho, HPS bulbs are now also being made with 'dual spectrum' meaning they have enough of the blue and red bands of light to see your plants through both stages of development.

You will find many benefits to HPS bulbs:

The efficiency, in terms of lumens each watt, is higher. There's usable light at a greater distance through the bulb, compared with fluorescent tubes. In most domestic installations, you can find only one particular or two bulbs to adjust as opposed to maybe twelve or far more fluorescent tubes.
bulbs possess a long lifetime of 20,000 several hours or much more (despite the fact that the output drops, gradually, throughout the life with the lamp - it's greatest to adjust them after a single year's use)

The disadvantages are:

The price of an whole program comprising handle gear, lamp and reflector may run into a couple of hundred Euros. HPS bulbs should usually be kept at least 18" above the plants to prevent leaf scorch or even fire except if you are using a Coolschade Cooltube! Water must be kept properly away from the bulbs as they can explode if splashed.
