Lights are on for 16 hour per day and energy costs of 17c/KW hour. Fixture cost based on todays prices Power consumption based on generating 210umols PPFD over three years. ![]() This equates to about 600umols PPFD average across the 60cm x 60cm grow area. Grow area walls: Silver mylar, diamond pattern 16 PPFD measurements taken for each test.įixture cost is a quantity of light fixtures needed to generate 210umols PPFD.But don’t worry much because so you’re free to extend your grow space any time by adding one more light as these LED lights featured with daisy chaining ability. HLG QB 120 4K 61W (hanging height 30cm) VIPARSPECTRA V300 recommended for 2x2ft vegetative coverage at 24 height & 1.5×1.5ft flowering coverage at 18 height.Viparspectra V300 132W(hanging height 35cm).150W HPS with Lumatek digital ballast and hammered aluminium wing reflector 165W (Hanging height 25cm).Lumii Envirogro T5 fluorescent 4 x 3ft tubes 100W (hanging height 10cm).The running cost is for 2.9 times a single unit to achieve the target PPFD level. The fixture cost in this comparison is therefore 2.9 times the purchase cost of a single fixture. We need 216/75 = 2.9 Lumii T5 fixtures to deliver the target 600 PPFD average to our grow. The target PPFD output for the light is therefore 600umols/m2.sec x 0.36m2 = 216 PPFDįor example the Lumii T5 fluorescent fixture outputs 75 PPFD. To compare these lights we have calculated the fixture and running cost based on delivering a target PPFD level across the 60cm x 60cm (2ft x 2ft) grow area of 600umols/m2/sec. Please see our article on the best grow light spectrum hereĮach grow light is different in size and outputs a different amount of PAR light. The % mix of green and red is not critical as both spectrum are very close in photosynthetic efficiency. Grow light spectrum are most efficient when the blue is mixed with green and red. Any less blue light and the plants are likely to stretch and any more than 20% is wasteful as it will not generate as much growth. They offer LED lights at an affordable price point, partially because the manufacturer themselves are selling these lights. ![]() Between 15% and 20% blue light is considered optimum for yield. This is a long and meaty review piece, so if you just want the quick take on Viparspectra as a brand, here it is: Overall, Viparspectra LED grow lights are a solid choice for beginner and mid-tier growers. The % of blue light is most critical to optimum plant growth. The balance of blue, green and red determines the type of growth you will get from the grow light spectrum. The Infra red (IR is the heat output) and the Ultra Violet (UV) ouput from each light and are not considered to contribute to plant growth.
