Light Density in the indoor grow room

how many grow lights do i need

or How Many Grow Lights do I need?

This is a common question for new growers, and goes hand in hand with

How many plants can I grow in this amount of space?

(which we will come to later).

Many people will talk about lumens per square foot but as lumens is a measurement of what the human eye perceives and not of the amount of light a plant receives and uses for PAR (photosynthetically active radiation) this is somewhat misleading.(Umol is the form of measurement used for PAR but is not given by many manufacturers). Novice growers often start off underestimating the amount of light they need to provide their plants because they mistake the brightness of the lights with what is necessary for a person to see by and not understand the quantity of light necessary for a plant to transform into energy and growth.

Grow room lighting has been established for a long enough period of time that we can discuss the number of lights needed in relation to the number of watts drawn over a physical area.

Using this concept of watts per metre the acceptable range to produce a quality product in terms of yield and strength is:

400 – 600 watts drawn per square meter

for a traditional High Intensity Discharge Grow Lighting (HID) set up. If you are using LED Grow Lights you can cut this by 25% so the average number of watts per meter ranges from 300 – 450 watts drawn/meter.

 

 

If you are using a 2.4m by 1.2m tent then the square meterage is 2.4 x 1.2 = 2.88m.

The minimum amount of lighting you want for this tent is:

2.88 x 400w = 1,152w so 3 x 400w or 2 x 600w HID lights will cover it nicely.

To maximise yield and resin production then look at

 2.88 x 600w = 1752w = 3 x 600w HID Grow Lamps.

  • If you’re using LEDs, then this size tent would want 2.88 x 300 = 864w drawn (you can probably get away with 2 x 400w draw lights) up to 1256w drawn (3 x 400w draw LED grow lights)

 

If you are growing in a larger space eg 3m by 4m the easiest way to work out the number of lights is to plot the shape of the room on squared paper and divide off meter width rows leaving access passages in between. The end of each access passage can be a grow space too. Divide each growing row into meter lengths then count the number of grow squares you have. Each square needs either a 400w or a 600w light covering it. If your room is an awkward size remember that a 600w light will happily cover up to 1.2m by 1.2m.

[ux_custom_products cat=”grow-lighting” products=”” columns=”3″ title=”lighting”]

 

There are some variables you ought to consider when planning your set-up:

  • What stage in their growth the plants are at. The formula above is for plants in flower; during vegetative stage plants need less light.
    • Seedling stage 200 watts per meter of grow space
    • vegetative stage 300-400 watts per meter of grow space
    • flowering stage 400-600 watts per meter of grow space

 

  •  If you have a separate grow chamber to flower room, the number of lights can be less even over the same space.
  • If you are going to run a multiple light set-up you don’t need to switch on all your lights during veg.
  • If you use dimmable ballasts you can reduce power consumption by turning down the light produced.

 

  • Efficiency: somewhere around 450w/m2 the grams per watt figure decreases as you increase the light. Up to 650w/m2 trichome production continues to increase but this soon levels off as well.

 

  • Quality of equipment. High end reflectors, ballasts and bulbs can modify the number of lights you need to cover an area and the yield from that space.

 

  • Grower’s style. We all find a methodology of growing which works for us and the strains we enjoy cultivating. Inevitably this will have an effect on the set-up as it evolves.

A Quick Guide to Lighting for Indoor Grows

What are HID Lighting Systems?

How do LED Grow Lights work?

 

Using an IWS system in a professional set-up

iws professional hydroponics

iws professional hydroponicsHydroponics has many advantages for a commercial grow: yields are bigger and quality is excellent. NFT is a popular choice for many hydroponic growers: its been used for a long time, and the results compared to a soil grow are amazing. However on a large scale NFT has many drawbacks, especially in that it relies on multiple reservoirs needing maintenance. The Intelligent Watering System from Nutriculture (makers of the original NFTs) has been specifically designed with professional growers in mind.

The IWS Pro System runs 48 pots using an automated flood and drain method. A high pressure pump fills the “brain bucket” and the advanced timing system floods the 25mm tubing to the pots quickly and efficiently. The plants are flooded from beneath and as the nutrient solution rises in the pot it pushes the stale air out as it saturates the grow medium. As the nutrient solution drains from the pot new, richly oxygenated air is pulled in. This ensures that the root zone gets plenty of fresh oxygen, which is vital for good root growth.

Why Pro Systems?

iws proThe Pro Systems improve on the basic systems by filling and draining twice as fast, thus giving you more control and making sure roots are not left submerged. This is achieved through:

  • 7000L/hr nutrient feed pump
  • 25mm piping
  • 2 drain pumps
  • Higher rated control boards
  • We suggest using copper mats to prevent roots growing down & blocking the piping

Why IWS PRO is perfect for professional grows:

 

Big strong plants

When used in combination with Nutriculture’s Vegitator, the professional grower keeps his plants in vegetative stage growth for 4 weeks in a separate veg room.  Not only does this mean fewer cuttings are needed for each cycle, but they are not as susceptible to problems as young cuttings flowered early are.

But the eureka moment about this set-up as far as the Kannaponica team is concerned is this:

Its cleverness is hidden in its simplicity to use.

With one big flexi-tank, ongoing maintenance & regulation of the reservoir tank is a breeze compared with the numbers of tanks needed to fill the same physical space.

  • 1 tank to balance for EC & PH
  • Tank can be located outside the flowering tents so that unaffected by heat from lights
  • 1 tank to be chilled / heated

Discretion

Although not as important as the factors above, it has to be said that bringing the IWS system into an area is more discrete: the flexi tank folds down into a small area and the rest of the pots, inner pots and pumps fit into a few normal sized boxes. Not nearly so interesting for curious minded neighbours to notice!

 

Downsides to the IWS:

  • Reliance on 1 pump to flood the pots
  • Be careful not to overtighten joins, damaging the glands and causing leaks
  • Can be intimidating to put together first time
  • Floor has to be completely level for complete success.
  • Flexitank doesn’t come with extra holes at top for additional equipment such water chiller hosing or airstones /pumps cabling.

Que_es_PAR

PAR+ es EL recubrimiento interior óptimamente reflectante, desarrolladoexclusivamente para HOMEbox®. PAR+ es un ‘material inteligente’, que refleja sobre las plantas más energía favorecedora del crecimiento (la “luz PAR”) y menos calor. En el caso de otros materiales se ha revelado que del espectro lumínico de las luminarias convencionales se refleja más radiación infrarroja (calor) que lo que es necesario para las plantas. Desde que se presentó el material interior de óptima reflexión PAR+, muchos usuarios informan sobre mayores índices de crecimiento y una calidad notablemente mejor de la cosecha.

PAR son las siglas de Photosynthetically Active Radiation (radiación fotosintéticamente activa). Se trata de un pequeño espectro de la energía electromagnética (400 – 700 nm), el cual precisan las plantas para la fotosíntesis. PAR es, por decirlo así, el “combustible fotónico” de las plantas. Cuanto más energía PAR reciben las plantas, tanto mayor es el índice de crecimiento y, con ello, la floración y los frutos producidos. ¡En materia de crecimiento importa el nivel PAR, no los lúmenes!
