Bruce Bugbee, from USU (who has done research on indoor growing, growing wheat in space, yadda yadda), told me that he has used these at home:https://jet.com/product/bubba/1b5ff36289bf438cb655e229825f7024
He also specified to not get the purples, as "it's as good as white for growing plants, but the plants look terrible under the light.
You might be able to find this fixture from other vendors."
He also ended it by stating he has nine of the bastards over plants in every corner of his house. Sounds like a decent vote of confidence for me. I'm going to use them to start seeds for my buddies this year.
