Flowering plants need more red light as supplied by hps lights.
Best light to grow one pot plant.
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.
If your plant is not receiving enough light you will clearly know because it will begin stretching and reaching upwards having more upward growth than outward growth.
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 cycles or periods of time during which your plant receives light is also important.
How to calculate the wattage of light you require.
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 powered lights such as a 1500 watt 2000 watt or 3000 watt led grow light should be raised to 24 36 above the canopy.
We want to flood our plants with light food so that they have lots of energy to produce big potent buds.
Therefore we need to calculate the square footage length x width of our grow space.
The best lighting option for a marijuana plant is a 250 watt hid lamp so it may be worth it nonetheless.
Lower powered lights such as a 250 watt led grow light should be kept 12 24 inches above the top of the canopy.
High intensity lights are superior for growing cannabis because they produce more dense compact and higher yielding plants.
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.
2700 k is a very red spectrum for flowering.
Cultivate healthy plants year round with a full spectrum grow light like our top overall pick the roleadro led 75w grow light.
The cfl lamps are available in red blue and mixed colors.
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.
6400 k is a cool blue green light as needed for growth.
For example if you re growing a single plant a 1000 watt grow light will produce a larger yield than a 300w watt light.
Generally speaking the higher the wattage of the grow light you use the more weed your plant will produce.
Light color also called light temperature is described in kelvin.
The most important general rule to remember about light and cannabis cultivation is that red spectrum colors induce flowering while blue spectrum colors promote growth.
When growing cannabis a good rule of thumb is to use a minimum of 50 watts of light per square foot of grow space.
Many indoor growers will give their plants 24 hours of light while in vegetation to ensure their girls grow as big as possible.
