  • Wish I would’ve had this six years ago
Size: 4-Pack
OK, one of my pains in the butt about growing is watering of course. The system is awesome because it doesn’t depend on power. If it goes out, you’d be screwed. I finished one harvest and starting another in Flower. I give them the nutrition through the top every three days Otherwise just keep the container full once a week have to fill it. Love love love this product I can go away for a weekend and not have to worry. ... show more

  • A good system when setup correctly.
Size: 4-Pack
There is nothing more enjoyable than watching your plants react in joy with all leaves pointing upwards after reaching the wet shoestring from a water basin. It's really important that you read the instructions including the yellow sticker on the plastic black device that controls the water. You'll need to remove a Styrofoam piece. Failure to do so will prevent the device from working correctly and lead to failure. Also, failure to put the gaskets in correctly from the outside into the hole in the basin will lead to failure and flooding. This is an awesome system to keep the basins full of water. I connected 7 basins to one system and it really is a time saver filling a single 14 gallon container versus each individual basin. The main 14 gallon container is well manage and I'd recommend boosting its height by putting it on a smaaaall platform so the hose goes downward into the hole in the tent. I do wish the spout hole would be lower on the 14 gallon container. That is my only complaaint. I understand they put the hole higher for the gravity system to work but i dont like thewater sitting in the basin below yhe hole. This system works well when set up correctly. ... show more

  • Highly recommend
Size: 4-Pack
After switching to a self watering system, I will NOT be going back to the watering by hand. I thought my plants were doing well before, but after this self watering system my plants are flourishing. They drink when they need water. I haven’t had any leaks with it. Very easy installation. Water retention is great. I refill it about once a month. ... show more

The media could not be loaded. This makes it so easy. Great to use with a living soil for my needs. No leaks. Set up was pretty easy.

  • This product is a pain
Size: 4-Pack
I’m sorry that I don’t have a photo up, but this product is a pain in the butt to set up. It was a little difficult because it does not provide enough instructions so we had to go searching for it on YouTube and not everyone has it so you know how that goes And it leaks a little bit. I am not sure if I need a pump for this to work, but I am going to try something else because this product is really not working for me. I only put three stars because I haven’t tried other means of using it as yet, but I will keep you guys updated when I do. ... show more
