The local one stop cultivation shop. I’ve been frequenting Northern Lights for 20+ years after beginning my journey into cultivation. Always friendly, helpful and happy to assist . Tons of great products and extremely knowledgeable staff who don’t try and push the most expensive, most useless stuff on you, they just want you to succeed , the first time around. Even went out of their way many years back to deliver products I had no way of obtaining otherwise. Truly above and beyond. Don’t hesitate stopping by for any and all growing needs, or just to check out their products! Where else can you get farm fresh eggs, delicious, fresh honey and an entire hydroponic, soil or soilless setup w/ all the advice to get you started ? NLGS

Great place, great staff, great products. I’ve been utilizing NLGS for around 17 years now, no joke. My friend and I were pleasantly surprised to find this store when beginning our journey into cultivation. Dean helped me out HUGE and quickly became a friend and mentor, fast forward 17-18 years and employees and such have come and gone but the same great service and friendly people have always been found at Norther Lights, don’t hesitate to head in and grab some gear or just to gain some knowledge and insights. Tell ‘em Top Shelf sent you .
