So after using a couple versions of the "Gooseneck" style lights for a few months, I decided to upgrade to one of these for my greenhouse: https://www.amazon.com/gp/product/B07PL ... UTF8&psc=1
, I am extremely happy with this light and once installed my plants thrived. I then decided that I wanted to buy a small grow tent to use for germinating seeds and raising seedlings until they are big enough to go to greenhouse and then outdoors. I then purchase one of these:https://www.amazon.com/gp/product/B07PL ... UTF8&psc=1
and I am very please with this one also. I am using the Mars Hydro in the germinating tent and the Vivosun in the greenhouse. Although I check out the various specs on different lights, I like to judge for myself and I will say that both of these lights did not fail to impress. I am very happy with the results I am seeing. The Vivosun has an App that controls the light strength, on/off time and the fan. Can also be used with Vivosun grow tents and blowers, etc. I like being able to adjust the brightness of the lights depending on the needs. On 3/4 strength setting the Mars hydro does a really good job germinating. Full strength will throw the grow tent above 100 degrees F so have to calm it down. I really like the Vivosun as I can adjust at any time without opening anything up.
