hi all,
may i know how long i need to on the lights in order for the plants to survive and grow?
tks
Never create what you can't control
It seems like you have not done enough reading before going into planted tanks. You will have lots of problems if you do not have the basics on hand.
Have you read the stickies in this section? Do go through the sticky right at the top How to Get Started in Planted Tanks and all the links in them.
To answer your question directly, people usually turn on their lights for 8-10 hours long.
Photoperiod is something connected to type of plants and light intensity.
From experiment, photoperiod can be from as short as 5-6 hours and as long as 13-14 hours, achieveable without serious ill effect to the system.
On regular aquascape, as squee suggest, 8 to 12 hours is the rule of thumb.
On initial set-up of a system, people tend to shorten their photoperiod a tad bit. As the plants mature, photoperiod is gradually increased to full time.
hi Ah Tan,
I am no expert on plants. But plants are generally divided into high-light, medium-light and low-light plants.
High-light plants are very demanding in light intensity eg. cabomba.
Whether a plant will survive will depend on (amongst other factors) the amount of light that reaches it and satisfies its needs.
If not enough light is penetrating into the water to meet a plant's specific needs, it will not be growing well and might end up shedding leaves and growing into a thin narrow leaveless stalk which eventually dies.
How long to keep your lights on is thus dependent on many factors such as the type of plants in your tank, the location of your tank and even the depth of water of your tank.
hope that helps a little.
