Review: This Product works. - Transplant Shock. I have tees thst need this product whenever transplanting. I don't use this as a fertilizer. But it does ignite plant growth I noticed. It is one of the gest products so far for both transplant shock preventative, plant and root growth. I ran out but would like to buy it again. Fertilizer quality: It has unexpected and excellent Quality. I get big leafes. Size: I live in a small space so the size of the product suited my situation. I am sure they come in different sizes, for different needs. I ran out and brought one on thr fly from Home Depot. Really not the same Quality. I said to myself, I wish I had this one again. I ran out. Happy this review came up so I can add this to my cart.

Excellent kelp

### ⭐⭐⭐⭐⭐ Lush Growth, Minimal Effort — My Plants Are Thriving!
*by N***Y on August 12, 2025*

This kelp fertilizer is pure gold for any gardener. I’ve used it on everything from houseplants to veggies, and the results are consistently impressive. The blend of seven seaweed species gives my plants a noticeable boost in both root development and overall vitality. Leaves are greener, stems are stronger, and growth is faster. What I love most is how easy it is to use—just mix a small amount into your regular watering routine and let nature do the rest. There’s no risk of overdoing it, and it’s gentle enough for even the most delicate seedlings. Plus, it’s fully organic, which gives me peace of mind knowing I’m not introducing harsh chemicals into my garden. If you want a low-maintenance way to supercharge your plants, this is it. I’ll definitely be keeping a bottle of this on hand year-round.
