For Those who dare! This is a DIY parts kit for our 4 plant 13 Gallon Fallponic system. It does NOT include any drilled holes or PVC but includes all the other parts. This allows you to customize to your specifications and includes 4 extra feet of 3/4 inch tubing if you need to space them out farther. This is a build at your own risk kit, we are not responsible for any injuries or problems with your drilling etc. We recommend practicing drilling on an extra bucket or piece of cardboard to make sure you have the right size holes and spacing. You should watch our build video for tips and tricks on building this system! Good luck and have fun:) Gary

This Parts Kit Includes:
5 - 13 Gallon Buckets
5 - Plain Bucket lids
4 - 8 Inch Heavy Duty Gropro Net Baskets
10 - 3" Bulkheads
1 - Active Aqua 400 waterfall pump
5 - 3/4 Inch Active Aqua Bulkheads
3 - 3/4 inch Tee connector
3 - 3/4 inch elbow fittings
10 feet of 3/4 Inch Active Aqua Vinyl Tubing
1 - 4 Output Active aqua Air Pump
4 - Active Aqua 2x2 Airstones
4 - 10 Feet sections of green air tubing
1 - 250 Gallon Per Hour Bottom Draw drainage pump
10 feet of 1/2 inch drain hose
1 - Water Level Kit with blue sight hose and 1/2 inch bulkhead w/elbow and Clip
10x hose clamps

ASSEMBLY TIPS AND HOW TO FILL:
- New 3/4 bulkheads seal much better, put the rubber gasket on inside.
- Use hot water for the soft tubing! This expands the tubing which helps it go on better and also helps it seal better on barbed fittings.
- Lean the hump piece over as much as your tent hole will allow for smoother operation.
- IMPORTANT! When you fill the system, fill it to the bottom of the hump inside and out, then turn on waterfall (this will burp out the air in the hump piece) 
- Then top off to your desired level. It will always have to be above the hump to run properly and during early vegetative growth you will have to fill it up high      so it touches your starter. 
- I have never used hose clamps on any of our systems and have had minimal problems, some people do add hose clamps to our systems that is up to you.
- Dont snap shut the plant root access flaps! They are very hard to reopen!
- If your flaps start to loosen at the joint you can put on a strip of Gorilla tape or electrical tape to strengthen it up.
- Please watch our videos on Fallponics for assembly :) Thanks. And dont forget to tag us! #FALLPONICS - Gary :)

3" Bulkheads - 3 3/4" Hole Saw

    4 plant xl diy kit

    Posted by Rob on Jul 28th 2026

    This thing is great. I needed this as I was putting it into an ac infinity 5 x 5 that has the port hole in the middle. With a little ingenuity and planning, I was able to recreate the caterpillar as well as use a double sanitary tee to exit out the middle of the tent. The system went together easily, and there were no leaks from any of the ball cuts. I did have to add a few hose clamps to the waterfall outlets on each of the buckets as they were slightly leaking but other than that, no other issues. One thing worth mentioning is make sure you use enough force to press the PVC pipe into the bulkhead. It is a tight fit. As a sidenote, the whole saw cutter for the 8 inch net. Pat is no joke. It is the craziest thing I’ve ever used! I wanted something built with quality supplies and not break the bank. This setup rocks! Just want the videos before trying to assemble.

    Perfect

    Posted by Robert Russo on Jul 26th 2026

    This is exactly what I was looking for. I purchased this kit because I have a 5 x 5 AC Infinity tent. The bottom port holes are in the middle of the tent, which is different than the gorilla grow tent. I needed a kit that I could put together and have the reservoir bucket piping exit the center port hole. I was able to achieve this with a two-way sanitary drain in between the two buckets closest to the porthole. Followed the instructional video to a T however made my own adjustments to fit the tent that I have. Instead of running the 9 inch PVC piping like Gary dozen his videos. I used 10 inch PVC pipe to connect the buckets that were facing closer together and 15 inch PVC pipes for the buckets when they were spaced further apart. This gave me roughly 40.5 inches between all buckets regardless of the size. This allowed me to run them a little bit further spaced out but still centered in the tent using the provided 400 gallon per hour pump is perfect for the set up. I have experienced no leaking issues no flow issues and everything seems to be running flawlessly. It does take a little time to put together but if you measure twice and cut once you’ll be good to go, this kid is amazing and certainly well worth the cost.

    13 gal XL System that rocks

    Posted by Aaron on Apr 7th 2026

    So, where do I start. I'd rate this system in the following categories: - Instructions: 5/5 - The youtube videos are clear as day. - Quality of product: 5/5 - Top notch. Buckets are oversized (good thing), pumps are active aqua (great brand). 3" return lines are fantastic, GPH flow is excellent. Only small gripe would have been the waste line at 10' wasn't long enough for the distance between my tent and drain, but easy enough to buy a 25' line. I knew that going in so I have no problems what-so-ever with the after-purchase mod. Love supporting local businesses and when the product quality is as high as this RDWC system is, it's an easy buy. For those of you growing in 5x5's like me, get the DIY version so you can add 3-4" of additional gap between the buckets, the extra space will pay off and allow your plants to be bushier without shading each other out while still giving you enough space to walk around the tent.

    Easier than I thought.

    Everything comes in and is very well organized. Materials are high quality and you can tell Gary cares about his customers as he hand signed the invoice and writes some notes to help you out as well. Get a 8” hole saw, don’t use the death trap in his video lol. Either way, drilling large holes like this can get tricky when you have a lot of weight spinning on a drill, be careful… but rush, wear safety gear, lock your drill chick and get something to put in your bucket to protect it from a falling drill bit (if you happen to drill the lids on the buckets). I’ll be ordering more stuff, pa hydro simplifies the whole hydro experience by creating quality kits without any unnecessary “features” that simply add to cost. It may be a little cheaper as he mentions to put these parts together yourself, but really if you consider shipping costs and how many times you’re going to forget something and have to go here or there and waste your time this man really is doing the whole hydro community a solid by helping us get a quality setup going at a great price. 3” bulkheads used in this kit are the best you can find. I could go on… just get it if you’re on the fence.

    Perfect for getting into RDWC

    Posted by Matt on Nov 20th 2023

    I wanted to DIY but was a little overwhelmed at first trying to source everything I would need until I ran across a video on YouTube by PA Hydroponics, after watching the set up video and seeing the price of the DIY system they offer I decided to make the purchase. I have been nothing but happy with it so far! I’m only about a week into veg but I ran the system for about a week before putting the plants in and have noticed zero leaks and with the pump outside the reservoir I haven’t needed to get a water chiller. I couldn’t be happier!

    13gal system

    Posted by Csmith on May 20th 2022

    System was quick to setup for me. Have had it up and running and approaching week 2 veg. So far love the rdwc system compared to dwc although getting great results with both. The recirculation makes managing ppm and ph a bit less of a headache though with this volume of water I am using a bit more nutrients and such but extremely satisfied and highly recommend this system...

    DIY 4-Plant system

    Posted by charles smith on May 4th 2022

    While drilling was a PITA I still had the system up and running in less than 2 hours. The only slight drip(leak) I had was on the 3 inch elbow section where I guess I did not prime/cement enough, easily fixed. Moved from DWC to RDWC and love it! Circulating makes nut/PH control less of a PITA than my DWC system.

    4 - plant diy fallponics

    Posted by Anthony on Dec 16th 2020

    Awesome. I recently purchased the 4 plant diy fallponics system. It went together great and is working wonderfully. My girls love it. I watched the build videos with Gary and it was a snap. Worth every penny.
