I think the purple lights are just outdated. I think they were popular before they found out how to make full spectrum chips for cheap. And basil is one of my favorites! It’s so good on eggs and pizza. If you go on Walmarts website they have a box of different herb seeds that comes with 12 different kinds including basil. The brand is “own growth culinary herbs” I think it was like 10 dollars. I don’t know if you will be able to find it but that’s where I got all of my seeds from. I was happy because it came with stuff that I never even knew existed and they all have different medicinal uses too. I make a tea with lemon balm, and peppermint. It puts you to sleep quick if you have insomnia. My favorite herb in the kit was the thyme because it’s so versatile. It goes great on potatoes, and steak. Fresh herbs have so much flavor compared to the dry stuff you get at stores. it’s a good hobby and I have fun working on it everyday. It’s pretty relaxing. And if you look on the shelf there are led light strips attached to each shelf. I got those for like 15 dollars on eBay but they are not really strong enough to do much. They just add some extra lumens, the more lumens the better
