Humboldts Secret Tree Trunk, Potassium Silicate Additive, 32 Ounce

Works well and is strong so it last good amount of time

This stuff actually works. I have been a grower of a variety of plants for many years and found using tree trunk makes the stems and branches much more robust. Plants seem more healthy and resistant to insects and dry spells. Glad I tried it.

Great product, plants growing like weeds since first application.

Works as it should

Make sure you shake this before using as it separates a lot, it really helps stiffen plants up so they can support your buds. I’ve never had problems with this burning plants so I use it very early on and it helps get that trunk thick early on. In the late stages you’ll get lots of knuckles too from using this. Don’t need much either

The jug came opened, and the company was ready to go above and beyond to make sure i would be a returning customer.

I definitely recommend Humboldts tree trunk this a awesome additive I added this to my lemon tree regimen & in just 3 days the growth rate increased tremendously this product is a must buy it’s definitely worth the value & the size it’s functionality helps with the uptake of your current nutrients I guarantee you won’t be disappointed

This stuff does exactly what it says it will. It really was a game changer for me. Never seen my plants so healthy and thriving through out the whole grow. Made stocks and stems super hard and strong and even made the leaves strong no BS and cheaper than most others I have bought.
