I have been using HSN for over 2 yrs now and it is ABSOLUTELY AMAZING!! Have phenomenal results. My last 2 orders have had issues with shipping, I understand once out of company hands not much you can do on the other hand who you ship with is. When I reached out to HSS about the issues, nothing was done other than "well it is on its way" is all I got!! A returning customer of over 2 years and this is how I was treated. I am in the process of finding another nutrient, one I can get and with a company that cares about their customers!!

The Best of The Best

I have been using Humboldt Secret now for two growing seasons. My first was outdoors and my second was indoors. My plants have never been healthier. Beautiful lush deep greens with flowers that burst with color, vibrance, and aroma. I use the complete line including Flower Stacker and Sweet and Sticky. I could not be more pleased with the complete nutrient regime. Thank you for producing no nonsense quality nutrients for my girls.

At this point in time my review can only be based on the delivery. I have not harvested.

The item arrived quickly! I have been using it and the present results are good, the real truth will be with the harvest. I previously used the starter kit #1 and was happy, so I thought I would try the step up. I had to go online to get the feeding schedule for the added two nutrients for the kit #2 a bit inconvenient and it doesn't print well unless printed in black and white versus the instructions being on the box. I am anxious to see if there will be a difference!
