Helpful Growing Tips

Natural sunlight is the best form of light for growing plants.

Using indoor artificial lighting the life cycle of the plant can be controlled by managing the length of the light cycle. The life cycle of the Cannabis plant is determined by the daily photoperiod (hours of light per day).

A young marijuana plant tends to grow faster if it is grown under continuous 24 hour light for the first two months of it's development.

The best light for plant growth emits high intensities of the blue and red bands of the light spectrum.

If your lights, after being on for a while, are too hot to touch with your hand, they are probably also too hot to be close to the growing tips.

The amount of light you supply your plants depends on the size of the garden, but at least 20 watts per square foot is recommended.

Plants entering the vegetative stage enjoy up to twenty two hours of light per day, while twelve hours or less is required for flowering.

The more light you give your plants, the faster they will grow.

Lamps should be fixed to the roof in such a way that they can easily be raised as the plant grows in height. As the plant grows raise the lights keeping them 1 foot from the tops to avoid burning the tops.

The use of aluminum foil reflectors ensures that the light is spread more uniformly around the plants.

To increase the humidity of the air in a small, enclosed garden, place a small bowl of water in the growroom.

You could use a small fan to cool down your plants, if the lights in a small growroom raise the temperature too much. The fan will also strengthen the plant stocks.

Plants grown in conditions of varying daily light patterns will not settle into a regular life cycle and will grow poorly. Do not attempt to manage the sunlight by moving the plant in and out of natural light.

If there is insufficient light in the growroom, the plants will often grow tall and thin, in search of the light.

Do not "wake up" your plants by switching on the lights if they are in the dark period of their daily light cycle. Keep the dark cycle undisturbed from light.

Plants grown with a long daily photoperiod, will require more frequent watering than those grown with less light.

If the edges of the leaves near the lights and growing tips start curling up, it usually means that they are getting too hot.

A Cannabis plant will grow with as little as six hours of light per day.

A plant grown with insufficient light may sometimes develop disfigured leaves with only one or two blades per leaf.

If your growroom has a window, you should consider covering it up to prevent daylight from interfering with your own photoperiod.

Paint the walls, and even the floor and roof of your growroom white, for better reflection of the light onto your growing plants. Consider a reflective background on the surfaces.

Your yield is determined by the room size, not the number of plants. Too many plants in one area and many will grow small and a few will dominate all the available light.

Although easy to control, the daily light photoperiod is the single most important factor influencing the growth of your plants.

Cannabis plants require less than twelve hours of light per day for at least two weeks before you can expect to see the first signs of flowers appearing. First hairs will appear at the joints on the females. At this stage you can verify the sex of the plant. Should you see any ball sacks in the joints then you have a male plant and should remove and dispose of it as it has no medical value.

Never increase the daily light photoperiod to more than twelve hours, once your plants have started flowering. Slowly decrease the light from 12 hours a day over the flowering period. Never decrease more than 6 hours per day.

A marijuana plant grown indoors with lots of light will often grow larger and more potent than a similar plant growing outdoors in natural light.

To increase the amount of light available to the lower branches, you could mount extra lights vertically, onto the walls or floor of your growroom.
