- GWGiegie W.Verified BuyerRated 5 out of 5 stars3 months agoWonderful product Sea-90
My Pakistani Mulberry tree is blooming and already had tiny little fruits on it just from using Sea-90 Mineralizer for the first time in March 2026. We live in the Phoenix Arizona area and the tree was dying and I saw a YouTube video on Sea-90 and tried it and couldn't be happier. My Jacaranda tree is getting better after use of Sea-90 Mineralizer. Happy customer for life.
- MMMatt M.Verified ReviewerRated 5 out of 5 stars1 year agoLove this so much !!! The very best Customer Service as well
This family owned and operated business for 70 years is amazing from their customer service to their great products!! This can be used for medicinal herbs, growing hydroponically, plus as a foliar spray is an awesome way to add minerals and elements to your plant through their leaves And stems! The plant will soak up all of the goodies from the sea of Cortez!! If you are a small craft farmer, the Grovers choice is the way to go. It lasted a long time and I need to find the foundation which is an awesome product as well.! I always add a pinch to the Medium! Uncle Jim’s Worm Farm Blessed us with enough Red wiggles to kickstart our Verma composting stations , And we are looking to scale up, especially once we begin picking up all compostable food waste for more local restaurants!!

I have been using Sea 90 in my Wicking Tubs. Thought maybe the Sea 90 Mineral Plus would even work better..
- DBDeana B.Verified BuyerRated 5 out of 5 stars2 years agoLove it!
Sea 90 that is soluble is awesome! This is my first try for the soil mix and I cannot wait to see how amazing my plants look! Believe it or not pests and disease are often from poor nutrition. I see wonderful improvements!

Hey all,
Some products are hype and some products are a Grand Slam in results. I have been using Sea-90 in my personal medical grows for over 5 years. There's nothing like it for the highest quality cannabis. Your health deserves the best in comforts.
