i almost want to say that grow ace tossed a hortilux into the socket for this test. .then claimed it was their bulb.. lol. because hortilux vs yield lab in my garden proved hortilux destroyed it..
Yes, but how well would these bulbs do in comparison to the top 2 bulbs on the market, Eye Hortilux and Ushio? I'd love to see side by side comparisons on clones..just to keep it fair.
