Works amazing! Just be careful opening!
5 Stars
Works amazing! Just be careful opening!
Love this stuff! First 3 pictures are over the first 3 days of seed, and the big compilation picture is also over a 3 day period just a week and a half later, this stuff really works!I would be cautious and gentle when opening the bottle though, as inside the rubber seal can get stuck, and so when pulling it out you could spill or make a mess if it's taken out too forceful. Ask me how I know, lol.Overall, I would recommend and purchase it again!
Thank you for your feedback
