video Home Made Vertical Hydroponic System
I saw a vertical hydroponic system that I really liked but what I didn't like was the $500 price tag.  I thought about it for a while and decided I could design my own system that is similar for much less money.  After about a month of spending weekends running back and forth to the hardware store I came up with this system shown in the videos below.  I call it The Rain Tower because there is a pump in the resivour that pumps the nutrients to the top of the tower and they rain down on the roots of the plants on the inside of the tower.

In this first video above is the test run I did growing 12 lettuce plants.  The results were amazing as you will see.

In this second video I take you step by step showing you all the parts you need and how to put it all together.  Links will pop up during the video but if for some reason you don't see them you can visit the web page here: The Rain Tower Home Page

I want to know why the 15 min on/of cycle? I am 99% sure that it would be better for the plants if the pump was on the entire time.

I sent you an email but never got a response.

I was asking about better materials to use than epoxy (which is pretty toxic), and now I am planning on just using normal schedule 40 PVC cement, as that's already intended for safe use with water lines.

Why did you use the epoxy? It seems like a bad choice to be around plants and water for plants, just for safety concerns.

Is there any reason not to use PVC cement?

I would have used something else like other people have been. That epoxy is expensive too but it held up. Mike Walker was using a PVC cement that he said he found near where you buy the fence posts. I haven't looked into it. There are some food safe PVC cement products on Amazon. The actual fence post and 3" PVC pipe are safe. I just checked into that recently and called the manufacture.

oooh... that's good news! I didn't think that vinyl fence posts would be food safe. Is it just their product that's safe, or are they saying that all vinyl fence posts are safe? Did they give you any details about why it's safe? Thank you for your help!

Call the manufacture. 1-800-336-2383

They make it for Lowes and Home Depot.

Press 3 for the tech dept. Ask if it's safe for growing plants. Really nice guy there.

This is PVC 4 LDPA - Low
-density polythylene �" not known to leach toxic
chemicals

Thank you!

Yeah, I wasn't concerned about the post or pipe, both seem to be the same material, and I know PVC is safe. I had to order the fence post online, unfortunately, and I just looked and it looks like he uses PVC fence post cement, which does in fact appear to work well.

I guess my concern just comes in with the (minute, I know) amount of potentially malicious chemicals that could come with that. I know Schedule 40 PVC cement is supposed to be non-toxic (as it commonly holds water line connections together), but I'm also worried that it won't be strong enough to hold more of a joint connection like this, instead of just holding together two pipes that are stuck together with friction. I plan on trying it to see how it works, but maybe I'll research the PVC fence post cement more too, but not being made specifically to be drinking water safe scares me, but perhaps unnecessarily.

Thank you for your diligent information though, it's inspired me to build one, I just need the time to start the construction, now that all the supplies finally came!

I used aquarium silicone... good hold... clear... and fish safe...

got it at Home Depot in the Glue section

Thanks for the tip!

Just ordered some, I'll have to try it out. Looks like it'll be handy around the house a lot too!

Hi, I wanted to know if anyone had any issues with humidity and mold growth on the inside of the tower. I was trying to do it in my house and a 15 min on/off cycle was causing some weird mold growth in the tower. Also, what about preventing mosquitoes?
