Humboldts Secret Flower Stacker – Best Flowering Formula for Bigger Harvests - Flowering Plant Food – Nutrient System for Potting Soil for Indoor & Outdoor Plants - 2.5 Gallons

I was a little skeptical in buying this product because I usually buy the ones that you twist on to the hose and the water mixes with the fertilizer. But, after seeing my flowers bloom I had no problem mixing the fertilizer. You use a very little amount so it will last me for quite a while. I will absolutely 100% buy this product again. I spend a lot of time in my garden. It is my zen zone. Good stuff!!!!

Be careful to read the directions. A little goes a long way. My plant loves it and has rewarded me with more flowers than ever. Great product and I'll stock up for next season.

Recieved product a week into flowering cycle. Used weekly as directed & had good results which led to nice harvest.

Great product. Had great success with plants. Very easy to use.

Concentrated, easy to use. Makes my brugmansia (angel trumpet) go crazy.

My flowers are swelling up huge from adding this to my cocktail. I use this with Fox Farms.

Way better than Big Bud...Two weeks at 3ml daily feed i wouldnt of believed it...Well spent money..

The media could not be loaded.  Daddy like!How is this evening happening? These pictures were taken January 1,2021 and according to my wife are about 11 weeks old. For the last three or four weeks the daytime high temperature has 68°. And at night of about 45° . And the plants seem to love it.Look how tight the bud blossoms are, it’s like one big forearm. I will bring it in soon put it under my grow lights and see how it likes that environment. The temperature is a low of about 65°F, and a high of 75°F. It’s flowing season here with 12 hour days similar to what the bud was getting outdoors. I will use flowers shield Humboldt flower shield to get any pest or mites or anything that might be on it off of it before I bring it inside grow roomAlso in the garden we have passion fruit that is 35’ long by 12’ wide. It took over a clothes line and outdoor clothes away but I put number 10 copper wire honored to support the passion fruit tree. We have a minature orange trees to produces grap fruit sized oranges when it wants to. The lime trees love the sweet and sticky as well. I want to see how good they’re going to taste. Ever fruit tree loves Miracle grow to grow foliage nice and green the fruit as well but that was in the summer. should’ve taken a picture of it I have a lot of little baby lemons and I limes. Once the flowers turn into small fruit the trees get Humboldt stacker. We harvest passion fruit pretty much every few days for a couple of months or longer. I forgot I started with a 4 ounce bottle of the stacker and sweet and sticky by Humboldt. For my cannabis plant growing indoors just a couple of plants. And I realized I started buying the larger bottles because it makes our fruit trees produce really delicious fruit. It might seem like a lot of money at first but the stuff is very concentrated and it goes along way.Our passion fruit already has blossoms were still using miracle grow. I still have Humboldt stacker and sweet and sticky for this year I’ll probably buy some more because it’s worth it it’s very concentrated.
