Review: Hugely Successful Grows with Humboldt's Secret - I use the whole Humboldt's Secret nutrient line on plants grown indoors in tents with automated lighting, circulation and exhaust fans and manual feeding, watering, temperature and humidity controls. My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings. On average, I'd say my return on investment in yield:nutrient is about 50:1. Hard to argue that. I'm a believer.
Review: Came in great shape works as labeled - I’ve been using these for my “tomato’s” and honestly works great makes your plant grow like crazy if it’s your first time maybe try there stater kit
