When growing cannabis a good rule of thumb is to use a minimum of 50 watts of light per square foot of grow space.
Best light to grow one pot plant.
Therefore we need to calculate the square footage length x width of our grow space.
Generally speaking the higher the wattage of the grow light you use the more weed your plant will produce.
The best lighting option for a marijuana plant is a 250 watt hid lamp so it may be worth it nonetheless.
Flowering plants need more red light as supplied by hps lights.
While you can somewhat increase the intensity by moving the grow lights closer to the plants it s best to choose a high intensity grow light from the start.
For example if you re growing a single plant a 1000 watt grow light will produce a larger yield than a 300w watt light.
High powered lights such as a 1500 watt 2000 watt or 3000 watt led grow light should be raised to 24 36 above the canopy.
2700 k is a very red spectrum for flowering.
The summer time is the best for this process.
Position this grow light above or next to plants at any stage of growth including seeding vegetative or flowering for a boost of full spectrum lighting.
Light color also called light temperature is described in kelvin.
Ideally leaving a pot under light for 18 20 hours a day for 4 6 weeks during veg is perfect for growing a nice healthy plant.
High intensity lights are superior for growing cannabis because they produce more dense compact and higher yielding plants.
However how do you know the exact wattage of light you require.
6400 k is a cool blue green light as needed for growth.
Mid range lights such as a 600 watt or 900 watt led grow light should be 14 36 inches from the top of your plants.
We want to flood our plants with light food so that they have lots of energy to produce big potent buds.
Then using a simple fluorescent bulb cfl s t5 s t8 s you can supplement the extra light needed to keep the bud lit up even when the sun goes down.
The best method is to place your plant near by a sunlit window if the climate you live in allows for enough sunlight during some months.
The cfl lamps are available in red blue and mixed colors.
Lower powered lights such as a 250 watt led grow light should be kept 12 24 inches above the top of the canopy.
How to calculate the wattage of light you require.
The cycles or periods of time during which your plant receives light is also important.
Cultivate healthy plants year round with a full spectrum grow light like our top overall pick the roleadro led 75w grow light.
