to grow 4 plants. Then what we should aim for

is a light that casts 45000 Lumens. This means

we should buy a 600-Watt HID system. Let’s say

we want to pump up our available light to

around 60,000 Lumens. This means we should buy

a 1000-Watt HID system. If our area is bigger

we might need 2 or more 1000-watt HID lights to

achieve this. It all very respective to the 3

elements we mentioned above.

There is nothing wrong if you want to use a

1000 - watt HID light on 2 plants. They will grow

bigger and better. The only thing is, do we

really want to spend all that money on the

light and the electricity bill? HID lights

range anywhere between $220/£200 and $700/£670

for a full kit. You may be able to buy the

parts and build your own, but this is only

recommended if you have some experience with

lights first. A 600W HPS kit should cost about

$250/£230. This is money well spent if you want

great plants with big buds.

Over time you will understand more about

grow rooms and how to light them properly. With

experience you should be able to tell what

light suits your needs. As a general rule, when

in doubt buy a 400W HPS or better.
