Humboldts Secret Set of A & B Liquid Hydroponics Fertilizer - World's Best Nutrient System – Hydroponic Nutrients for Outdoor, Indoor Plants – Supports Vegetative and Flowering Stages of Plants

I use so little 5ml to 12ml of each per gallon of water and I am amazed at how well everything is growing in my hydroponic gardens.

I had to quickly find a new fertilizer ever since my favorite company decided to go out of business. Humboldt Secret did a fine job with my habanero peppers that I was growing in my hydroponic unit.

The media could not be loaded. This is my first attempt at hydroponics! This product was easy to use and my garden is growing like crazy, so it works! My plants are very healthy and taste delicious! The greens grows so well that I have to pick off of them and eat a big salad daily so I don’t run out of space! Happy customer!

The nutrients are awesome and i will continue to use them. They will almost always be leaking when you get them because the liquid will eat it's way completely through the seal and at times the bottle itself looks melted. I wish they would do something about this but it seems to be a common complaint and no change yet. I have had great results using the product and I don't buy it for the bottle. Still wish I would get a full gallon when I pay for a full gallon though.

I’ve been using these fertilizers for the past couple of months and I really like them! My plants are happy (both hydroponic and soil) and I’ve not experienced any harsh effects like leaf burn, even on young seedlings. My hydro tanks’ pH also doesn’t fall off the charts every time I add new water with nutrients, so I have to wonder if there may be a buffering agent present… one of life’s mysteries. In any case, the actions of the product are gentle but effective for good plant growth.On my wish list is product labeling for smaller quantities shy of a gallon (e.g. mix X amount of product with 1 gallon of water). I often water by the cup or the liter and rarely a gallon in my home setup, so I had to make my own conversion chart.If you haven’t yet found a solid, reliable and affordable option for your plants, and you’re looking for something in the all-purpose category that most plants will love, I highly recommend this. Also, it ships to California markets which many fertilizers do not.

Wonderful results with a great price point and high grade nutrients. I switch between these and advance nutes depending on price or sales and they make plants grow like crazy. The nutes don't have horrible smell like some

This stuff probably works great. Nothing noticeable after only a week. I have high hopes. I won't be buying anything more from this company because they suggest buying an additional product for it to work well. This was never mentioned in the information on the product description. I feel a little scammed, I would have bought it if it would have been mentioned.I bought this just for my regular garden veggies, I will write a glowing review if my garden does better than normal.A couple of months later and my garden has done the best it ever has, still won't buy it again because of the shady sales tactics.

Water soluble. Easy to use. Great results
