## Customer Reviews

### ⭐⭐⭐⭐⭐ Eco-friendly Plants
*by M***K on March 29, 2021*

The seeds germinated quickly and are growing well in the repurposed howlers I have them in. Some of them got a bit leggy, but that's my fault (seedlings need good light and I didn't think to have a grow light on them right away). As a positive that isn't really discussed anywhere in the comments, I think these are fairly bug proof (*knock on wood*). I had ants get in through a window near these, and instead of burrowing into the soil, they just drowned in the water. That's a massive bonus! I'm curious if they're fungal gnat proof . . . Hopefully I won't have to find out!Compared to other grow-a-plant-in-a-jar options out there, I really like this one. I've already recommended it to several people and plan to buy it again. I think the negative reviews are based on a) not reading that this doesn't come with 3 bottles and b) people who haven't started seedlings before. If you're like me, you can easily repurpose howlers or litre beer bottles, so the bottle thing isn't really an issue (I'm guessing the people who struggle with that don't drink beer or wine?).

### ⭐⭐⭐⭐⭐ Perfect for me! Growing, Gorgeous and Blooming
*by A***E on May 30, 2020*

Started Thai, Purple and Lime Basil's on the window sill on 4.17.2020 and today is 5.29.2020, when I took the most current pictures. Each day I make sure the vases are always filled to the top with water (not obsessively, but at least 3-4 times a day) and alternate positions of the plants as the sunlight moves in the west exposure (live in the Phoenix, AZ area).That is it and so far so great!

### ⭐⭐⭐ Disappointed!
*by J***E on August 8, 2023*

This is a cool idea! Kit and contents are attractive and instructions easy to follow. Some seeds sprouted in a few days. When I carefully removed the germination covers, the adhesive pulled the seedlings with them! Needless to say, I’m very disappointed! I sent pics of the bottles to friends and family with a promise to report on the progress and had planned to buy all the other versions. I decided to try again with the remaining seeds. I put a couple of drops of water on the top of the planting medium to remoisten it and planted more seeds but used plastic wrap to cover the tops. I won’t be buying the other kits and recommending them to friends until I see if my modification works.
