Cheap Grow Lights For Bonsai
For growing bonsai plants, cheap grow light indoors often becomes insufficient. So plant grow light is better outdoors, which is the reason why bonsai plants are mostly grown outdoors. It may be imperceptible to our eyes, but the truth is plant gets cheaper grow light, the more it is away from the natural source of light.
It is said that indoors, the plant grow light levels reduce by half, with every 50cm from the window. This means light for plant growth is too low, even if you are having a bright windowsill. Glass cuts off most of the UV rays that plants need for photosynthesis resulting in cheap grow light. Bonsai trees near windows facing south may get only very cheap grow lights, even though the sun might burn their leaves.
Cheap grow light is sure to hamper plant growth. Any attempt made to grow will result in long internodes, and the plants tend to become ‘leggy’. In the effort to catch maximum light, leaves will become over-sized. To get the required plant grow light, trees grown indoors should be placed near sunny windowsills or provided with fluorescent lamps above it. This could be more than enough for many tropical plants but not so for ordinary woody temperate species.
Aquarium lights or ordinary fluorescent lamps kept about 6 inches above the tree for 14-16 hours every day can be used as supplementary lighting arrangement. Also it is not advisable to place trees near windowsills, closed with curtains during night. The temperature in between the curtain and window can dip rapidly at night, resulting in cheap grow lights.
