How to Choose the Best Grow Lights
Your window sill will not be able to do as good a job of propagating your favorite indoor plants as the products featured in the best grow lights reviews. With the proper lighting rig, you can easily get the most out of any indoor garden. To ensure that, take note of the following elements to look for in this type of equipment.
Most plants exhibit positive phototropism, which denotes their tendency to respond to light by moving towards it, following its direction. This is opposed to negative phototropism, which refers to the inclination of other plants, or other organisms for that matter, to move away from the light.
When positively phototropic plants grow elongated or tall stems, it means there is not enough light. The stretching of the plant is due to it finding additional energy instead of producing leaves to harness that energy.
Indoor plants do not have that option, which makes the products in the best grow lights reviews an essential element in any indoor gardening setting. This doesn’t mean, however, that one can just plop a 1000-watt lamp over indoor plants and it’s all done. A sensible balance needs to be achieved between the volume of light produced and the generated waste heat. Too much heat dries up specially sensitive plants, especially in the sprout or seedling stage.
Most of the top rated grow lights 2021 are fluorescent types. A popular mainstay of any modern nursery, fluorescent light bulbs provide low heat production, making them perfect for nurturing sprouts, seedlings or baby plants. Herbs, spinach and leaf lettuce grow nicely under fluorescent tubes. Although the most common style of fluorescent is the T12, many best selling grow lights carry the T5 style. T12 has been around for such a time that it may easily be eased out by T5, which offers better light quality, burns fewer watts, has higher color temperature options and has lower maintenance costs due to its better bulb life.
A newcomer is LED, but it could very well become the future of indoor horticulture. Working like any other LED light, this type has a cluster of low-watt LEDs configured on a circuit board and producing light. Unlike high intensity discharge (HID) rigs, LEDs are exceptionally energy efficient. They are capable of generating the precise wavelength of light stated in their specs and no greater. In addition, some LED lighting rigs can generate light at two distinct/dual band spectrum points with minimal heat production and minus the bleeding into other unusable wavelengths.
The spectrum of light is an essential factor in horticulture since each spectrum induces a different response from various types of plants. This will have something to do with the type of lighting rig to go for, as some types are oriented toward certain parts of the spectrum while others are able to span multiple wavelengths.
Contrary to the claims of plenty of amateur closet gardeners, plants do not need 24-hours of sunlight. Without occasional darkness or shade, plants can’t make buds. A fair amount of vegetative growth takes place in the dark hours, therefore, changes in the day’s duration can have a direct effect on fruit and flowering capabilities. Between plant species, the preferred balance can be distinct between dark and light. Some experts forward that plants need 20 hours light exposure alternated with 4 hours off in the vegetative growth stage for that popular closet crop.
