I bought these because it says on the label that they last for 3-4 months. I put them into the substrate under my plants, and my plants are thriving and making new leaves very quickly. They were easy to place into the substrate, and I had no issues with them dissolving in my hand as with other root tabs. Other root tabs only last about 1 month, so I love that these are supposed to last 3-4 months. I will continue to watch and see, as I have only had them for 1 week.

Would buy this product again. Shipping was quick.

Seems to work great so far, new plants are thriving with it

Seems to do a lot for my plants, could tell a change within a couple weeks.

Easy to apply to substrate. Hold capsule firmly and bury immediately.

I received my Thrive caps on Monday and immediately put them in my aquarium that evening. By Wednesday night I saw noticeable growth in all my plants (anywhere between .5-1.5 inches, depending on the plant). I am shocked by how well they worked. Worth every penny!

I love the feeling of adding this in with the liquid form to be sure that each plant is getting what it needs! super easy to use! I highly recommend adding this is with the liquid! my plants have done great!!!!!

Plants look alot better, Faster growth

Was very happy when I counted them out and had more than 60, however, I’ll have to reserve full judgement until a later date to see how well they grow my plants.
