I started with two purple lights 3 years ago. They can grow weed ok. If you decide to continue I guarantee you will upgrade those within a year. Before you do ask here for help choosing. Growing cannabis is such a lucrative business right now there’s a lot of companies flat out lying about their products. Lights top the list of misinformation. Many of the reviews are paid for and not true.
I still use my purple lights to start seedlings and I have one over a Mother plant I keep alive.
Don’t feel bad because there are many of us who did the same thing. There is even a thread dedicated to it like a support group…
