To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This products works great. I used one drop to cover the fresh end of store bought mint and kept it in water, it rooted within 5 days. The reason I took one star off is because it is not very easy to use. The white membrane that is used to seal the bottle is extremely difficult to remove with gloves on. There is no dispensing system, and I didn’t think dipping things directly in the bottle was a good idea, as it mostly likely will lead to contamination. I ended up used a tooth pick to take a small amount out. I wish it came with a dispensing system.
Just used it about a week ago and rooted two cuttings in rockwool. After 5 days of sitting in a terrarium, I planted the clones in a coconut fiber growing medium, after three days, started seeing new leaf growth on one of the cuttings, the second was a bit harder stem and is going a bit slower, but is showing signs of taking off. This puts me about a week and a half ahead of where I'd be without using a rooting agent. The advantage I have found with the gel over a powder is in that I use rockwool blocks, the gel stays on better when inserting the cutting stem.
