Early Growth
Once the seeds germinate, the light is kept on for 18-24 hours a
day. Some growers think that there is no significant difference in
growth rates between plants growing under 24 hours of light a day
(continuous lighting) and those growing under an 18 hour light
regimen. In controlled experiments there was a significant dif-
ference: the plants get off to a faster start given continuous lighting.
Some growers cut the light schedule down to conserve electricity.
Plants grown under continuous light which are moved out-
doors occasionally experience shock. This may be caused by the in-
tense light they receive from the sun combined with the shortened
day length.
Another popular lighting regimen starts with continuous light.
A week after germination the light is cut back one hour so that the
regimen consists of 23 hours on and one hour off. The following

week the lights are cut back again, to 22 hours of light and 2 of
darkness. Each week thereafter, the lights are cut back another
hour until the light is on only 12 hours a day.
Whenever a light is to be turned on and off periodically, it is
best to use a timer to regulate it. The timer is never late, always
remembers, and never goes on vacation.
Plants are at their most vulnerable stage immediately after they
germinate. They are susceptible to stem rot, which is usually a
fungal infection and occurs frequently when the medium is too
moist and the roots do not have access to oxygen. On the other
hand, if the medium dries out, the plant may be damaged from
dehydration.
Mice, pet birds, dogs and cats have all been noted to have a
fondness for marijuana sprouts and the young plants.
Seedlings given too little light or too warm an environment
stretch their stems. The long slender shoot subsequently has pro-
blems staying upright - it becomes top-heavy. These plants should
be supported using cotton swabs, toothpicks or thin bamboo
stakes.
Most seedlings survive the pitfalls and within a matter of weeks
develop from seedlings into vigorous young plants. During marl
juana's early growth, the plant needs little special care. It will have
adjusted to its environment and grow at the fastest pace the limiting
factors allow.
If the plants are in a soilless mix without additives they should
be fertilized as soon as they germinate. Plants grown in large con-
tainers with soil or a mix with nutrients can usually go for several
weeks to a month with no supplements.
Within a few weeks the plants grow quite a bit and gardeners
thin the plants. If possible, this is not done until the plants indicate
sex, so that the grower has a better idea of how many plants to
eliminate. The most vigorous, healthy plants are chosen.
