High Efficacy 640W Led Grow Light Sale

High Efficacy 640W Led Grow Light for sale

When shopping for grow lights, you’ll notice they are labeled with numbers like 2700K or 4000K. This refers to their relative warmth or coolness on the color spectrum – the higher the number, the cooler the 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.

Best full Spectrum designed, is a full-cycle top-lighting solution for commercial growing cultivation, with the power to scale from vegetative growth to higher light intensities in bloom.

This Led grow lights consistently emit wavelengths in the range of 380 to 779m.

PPFD Measurements and What`s Best for Your Plants

We will provide real testing data for your reference.And then you can choose a suitable led grow light for high Yield.

Between 200-400 PPFD: This is great for seedlings, clones, and mother plants.

Between 400-600 PPFD: This is great for early to late stage vegging cycles.

Between 600-900 PPFD: This is great for the flowering, fruiting, or budding stage of plants.

Between 200 PPFD and 400 PPFD, plants growth rate potential crawls around 30 – 55% which is recommended for mother plants or young, weaker plants that need a light that`s not super intense.

If you were to double your PPFD from 400 to 800, the growth rate potential reaches about 85%. You would think that doubling the intensity would push the growth rate potential pass 100% but the truth is, there`s a loss of power in return the more intense your lights become.
