Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum. They’re excellent for seedlings as well as houseplants, culinary herbs and other plants.
In this way, how many lumens do I need for a grow light?
Vegetable seedlings and other “full sun” plants require about 2000 to 3000 lumens (at minimum) per square foot of growing space. So, if you’re growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens is sufficient. Otherwise, do the math and scale up to a brighter light.
In this regard, do regular lights help plants grow?
So, to answer the question, yes you can use a regular light bulb to help plants grow. … Be sure not to overheat the plant or to give it too much sun. Most indoor plants are chosen for their ability to survive in less light. You may find that you do not even need an extra light bulb to help them along.
Will any LED light work as a grow light?
Regular LED lights can’t be used as grow lights, even though they may emit some of the wavelengths necessary for plants. Regular LED lights don’t emit enough of the light that plants require. Plant growth primarily requires red & blue light, which LED grow lights are designed to maximize.
The optimal number of lumens is 7000 to 7500 lumens per square foot. … If the plant is in the vegetative phase, 2000 to 3000 lumens per square foot is the minimum amount. However, in the flowering phase, 5000 to 10,000 lumens are recommended.
Both 5000k and 6500k are great for the vegetative phase, flowering phase, and fruiting phase. So, they are ideal for the general growth of your plants. The only difference between 5000k and 6500k is that 5000k is considered morning light. On the other hand, 6500k may be regarded as noon light.
Foliage growth is generally best around 6500K, though many plants need a period of warmer light, around 3000K, in order to produce flowers, and thus fruit. In other words, if your goal is to simply produce seedlings, leafy green vegetables, or root crops, you only need higher spectrum bulbs.
