What about this one? LED Grow Light bulb, 24W Full Spectrum: https://www.amazon.com/dp/B01GFWK69Q?psc=1 Or maybe this one? https://www.amazon.com/Apollo-Horticulture-Spectrum-Indoor-Growing/dp/B00PBCG8X0/ref=sr_1_29?ie=UTF8&qid=1478277659&sr=8-29&keywords=indoor+led+grow+lights+for+plants Sounds like I want to focus more on Blue and Red light spectrum to achieve chlorophyll and nutrient absorption. I wonder if 24 watt will do it. Should I shoot for high wattage? Please help, it’s been weeks and my spirulina are hardly growing at all!
