So I bought some led grow bulbs and from what I've read they should do the job from start to finish but I want your opinion as well. My area is 2'x2'x4'. So 4 square feet of growing area. My math says I should get 40.5 watts per square foot with these. Will these work? Specs for the first 4 bulbs Full spectrum for vegetative and flowering stage:Red:620~630nm,650~660nm, Blue:440~460nm, White:3500K 6000K, UV380~410nm, IR(730nm)(It is hard to see clearly by eyes, very dim.Please don't think they are not working. Instead, it plays an very important role in the flowering and fruiting stages of plants. Coverage Area: The lighting area and the height are changeable according to different plants and environments Lifespan: >30,000hours Worldwide Voltage: AC 85v~265v Working Frequency: 50~60Hz Specs for the 5th bulb Specification: Item Type: 5730SMD LED Grow Light LED Quantity:78pcs Wattage: 50W Color: Full Spectrum:42Red+18Blue+6White+6IR+6UV Base Type:E27 Lumens:2500-3200 Input Voltage: AC85-265V Lifespan :50000 hours Features: saving energy For: Flower Plants, Hydroponics and Vegetables and so on Thanks for your help.
