What SIze Light do i need?

Wattage	Approx. lumen output	Garden area covered	Area covered with sunlight
250 watt	28,500	3' x 3'/ 9 sq. feet	4' x 4'/ 16 sq. feet
400 watt	50,000	4' x 4'/ 16 sq. feet	6' x 6'/ 36 sq. feet
430 watt	53,000	4' x 4'/ 16 sq. feet	6' x 6'/ 36 sq feet
600 watt	90,000	6' x 6'/ 36 sq feet	9' x 9'/ 81 sq. feet
1000 watt	140,000	8' x 8'/ 64 sq. feet	12' x 12'/ 144 sq. feet

What about the different colours and light spectrums?

White/blue = propagation (seeds/clones)  Blue = vegative (growth) Red = Flowering (bloom)

What do you need?

Red and Blue light is essential for plant growth. It is well known that chlorophyll, which is contained in the green leaves of plants performs photosynthesis. Red and Blue are the wavelengths most essential for photosynthesis. The blue absorption region is 430-450 nm and that of red is 650-670 nm.

Recent research suggests that the ideal balance is 92% red LEDs and 8% blue LEDs. Although the lamps we use have a higher percentage of blue LEDs and they work fine. Blue has a smaller influence than red light so anything between 1% and 20% of blue light can be selected, depending on your plants and their growth requirements. When choosing your lamp you want both colours with the same frequency and relative intensity per LED.

These days most LED Grow Lights only deliver the colours of light used by plants for efficient and healthy growth. By leaving out the wavelengths plants wont need they provide better energy efficiency than conventional grow lights.

Red Light
Red Light is in the vicinity of the first peak of a plants light absorption spectrum (660nm) and it contributes to the plant photosynthesis. Red light, when combined with blue light, encourages flowering. It can also be used in higher doses to stimulate flowering, seeding and fruiting.

Blue Light
Blue light is responsible primarily for vegetative growth (leaf). It is known that chlorophyll has the second distinct absorption peak in the vicinity of blue light wavelengths (450nm). The blue light is also indispensable to the morphologically healthy growth plant. There is also more sunlight energy in the blue-green wavelengths

What Size Fan do i need?
if you would like to calculate  the size of fan you require simply follow these instructions:

Measure the Height, Length and Width (in metres) of the growing environment.

Multiply together (H x L x W) to give the cubic meter volume.

Multiply this figure by 20.

This is the size of fan required to change the air 20 times in an hour.

Buy the fan slightly above the figure calculated if possible to ensure adequate ventilation.

What Size Carbon filter do i need?

The correct filter is ideally one that matches the cm3 measurement of your fan for example

4" Budget Carbon Filter "160m3" 100mm x 250mm = 4" Rvk Extractor Fan - 100 mm A1 = "175m3"

We recommend that you renew the air within your grow room once every 2-3 minutes (30-20 times per hour).

To understand which size carbon filter is appropriate, first you need to calculate the volume of your grow room using the following formula:

Grow room Width x Depth x Height = Volume, for example:

Grow room 1.2m Wide x 1.2m Deep x 1.8m High = 2.59 cubic metres (2.59m3)

Now that you have calculated your grow room's volume, you now need to find out the recommended amount of air that needs to be renewed based on its volume. To do this use the following formula:

Grow Room Volume x Air exchanges = Recommended volume of air exchanges per hour, for example:

Grow room volume of 2.59m3 x 30 air exchanges per hour = 77.7 cubic metres per hour (77.7m3/hr), meaning that the 160m3/hr rated carbon filter is more than ideal for this size room.

What is the ideal temperature for plants?
Air temperature within the grow room should be between 77 and 83 degrees Fahrenheit. Water temperature should be between 68 and 72 degrees Fahrenheit.

Tell me about adding co2?

C02 should only be used when your lights are on, as plants only use CO2 during photosynthesis. C02 is most effective during the flowering stage, but BGH recommends using CO2 throughout the life of your plants for maximum results.

What Should My Ph Reading be?



optimum ph  for hydroponics being 5.8 and 6.5 for soil.
Different plants have different ph requirements, this is just a guidline.

What do i need to properly grow indoors?

1 – a room, grow tent or grow box.
2 – a grow light kit (bulb,ballast, reflector) bulb and ballast must me the same watt
3 – a contactor to allow the lights to be controlled by a timer without over loading it.
4 – an extractor fan ( for extracting the stale air and odour )
5 – a small intake fan for fresh air
6 – a Carbon filter (odour passess through this to eliminate odours)
7 - ducting and ducting clips to connect the fans and carbon filter together
8 – plant pots or a hydroponic system ( hydro plants grow 3-4 x quicker )
9 – growing medium (soil for plant pots) rockwool/clay pellets or alt for hydroponics
10 – a grow nutrient for the vegative stage
11 – a bloom nutrient for the bloom (flowering stage)
12 – a boost to add additional weight and yields in the last 4 weeks of flowering
13 – ph up ( to raise the ph of the water )
14 - ph down ( to reduce the ph of the water )
15 – a digital nutrient meter ( for testing/altering nutrient strength)
16 – a digital ph meter ( for testing/altering ph strength)
