How long do you run your grow light for?

#### maneaterさんが2024-06-14に返信しました

too long, usually about 8hrs. do you think that’s causing it?

#### Kadesさんが2024-06-14に返信しました

I actually think you need to keep it on for closer to 12-16 hours! I love grow lights but if you are using them as the sole/majority source of light you’ll need to keep them on practically all day. I have a few bulbs that are really dim that I leave on 24 hrs sometimes (usually when I forget)

Just to let you know I don’t have a periwinkle I was just looking into it after you posted.

My periwinkle is a vine, so it’s growing as it should.
