Right off the top, I bought 2 sets of this kit. The buckets w/ the net pot lids are worth the money by themselves. Having said that, here are the negatives. The air pump is garbage. There is no way this thing is rated for 8 air stones simultaneously for anything other than weak bubbles. It's not good enough. As many others have, I bought 2 different 4x pumps (variable) off amazon that do way better. Paid about $30 each. The air stones that come with this kit are terrible as well. Every single one of them broke at the neck when pulling the tube off. Again, that's an easy fix with $20 for a 10 pack of 1" quality stones off amazon. The buckets are quality for sure. The handles are robust and work really well. We are currently growing carolina reapers and I really like the smaller 5" size of the net pot in the lids. Requires less clay pebbles and there is no reason for 8"+ pots when the goal is to have the plant roots touch your nutrients faster. ALL THIS SAID:::: I have some comments about potential improvements. I have deleted the water level tubes. Dumb. Completely unnecessary. I taped off the two top holes and saved the grommets for later use. The bottom hole is PERFECT FOR THE AIR LINE. I cut an 8" tube and inserted into the bottom whole with an air stone attached in the middle of the bottom of the bucket. This way the stone is ALWAYS stationary in the center bottom of the bucket so you get the maximum agitation of the root system. It's a no-brainer. Also, the other end of the air tube is cut to about 2" outside the bottom of the bucket. You attach the backflow check valve and now you have an easy way to change out the buckets. Just disconnect the air tube from the check valve and swap in your prepped bucket. PHOTO INCLUDED. Anyway, this is a great beginner setup. You can play around with what works for you. Last comment: SUPPORT IS TERRIBLE. Sorry but you get what you pay for.
