AutoPot XL Systems, 1-100 Pots, 6.6 Gallon | Happy Hydro

6.6 gallons per pot, zero electricity, and every plant waters itself

The AutoPot XL System uses gravity and the AQUAvalve5 to deliver water and nutrients from a single reservoir to 6.6-gallon pots with no pumps, no timers, and no power. Each pot gets its own valve and tray, so every plant sets its own wet/dry cycle independently. The round pot base rotates inside the tray, giving you full access to the plant without disconnecting anything. Start with 1 pot and expand to 100 using the same reservoir and pipe run.

Plant-driven watering No electricity required Up to 50% water savings 1 to 100 pots, one reservoir

Hand watering vs. AutoPot XL
Hand watering
  • Water every few days, manually, per pot
  • Overwatering and underwatering depend on your schedule
  • Runoff collects in saucers, needs draining
  • Can't leave plants unattended for more than a few days
  • Each pot gets different amounts depending on pour speed
  • Scaling to more plants means more time hand watering
AutoPot XL System
  • AQUAvalve5 fills tray to 1" and shuts off automatically
  • Plants control their own wet/dry cycle through the valve
  • Zero runoff, water goes up through the root zone and stays
  • Leave for days or weeks, just keep the reservoir topped off
  • Every pot gets the same delivery from the same reservoir
  • Add pots with a tee connector, same pipe run, no extra work
What makes it different
Built around the AQUAvalve5

AQUAvalve5 with 5mm inlet 66% larger

The valve's dual-float mechanism fills each tray to exactly 1" of water, then closes. It only reopens after the plant has consumed the entire supply. The 5mm inlet is 66% larger than previous versions, reducing blockages and allowing liquid organic nutrients to flow through the system.

No electricity, no pumps, no timers

The entire system runs on gravity pressure from a reservoir raised at least 6" above the highest AQUAvalve5. No power outlet needed, no pump noise, and no single point of electrical failure.

Rotatable round pot base

The 6.6-gallon round pot sits inside a clam-shaped tray and spins freely. Rotate large plants to access every side for training, inspection, or defoliation without removing the pot from the system.

Expand from 1 pot to 100

Every system uses the same 3/8" pipe and tee connectors. Adding a pot means adding one XL expansion module and cutting in a tee. The reservoir feeds them all from a single line.

Works with any growing medium

Coco, perlite, soil blends, and clay pebbles all work. AutoPot recommends a 50/50 coco-perlite mix for best results. Heavier mixes benefit from adding an AirDome for extra root zone oxygen.

Up to 50% water and nutrient savings 50%

Bottom feeding means zero runoff. Water wicks upward through the medium and stays in the root zone until the plant uses it. Nothing drains out the bottom, nothing evaporates from the tray.

How the system works

1

Connect the reservoir

Attach the filter and inline tap to your reservoir (hard tank or FlexiTank). Run 3/8" pipe from the reservoir to your first pot, then tee off to additional pots. Raise the reservoir at least 6" above your highest AQUAvalve5.

2

Fill the pots with medium

Place a Root Control Disc at the bottom of each 6.6-gallon pot (or an AirBase if using AirDomes). Fill with your chosen medium. A 50/50 coco-perlite blend is the standard recommendation. For heavier soil mixes, add an AirDome for root zone oxygen.

3

Hand water for the first 2 to 3 weeks

Top-water your seedlings or clones until roots are established and reaching the bottom third of the pot. Then open the inline tap and let the AQUAvalve5 take over. Do not top-water after this point.

4

Keep the reservoir topped off

Refill when the reservoir reaches about one-third full. Never let it run completely empty. If the reservoir empties, air enters the lines and the AQUAvalve5 can lose its vacuum seal, which is the most common cause of system failure.

Questions
Frequently asked questions
No. You connect the pipe from the reservoir to the pots using push-fit connectors, place a pot and tray at each station, and open the tap. There's no wiring, no programming, and no calibration. The AQUAvalve5 handles everything from that point forward. Most people have the system running in under 30 minutes.
Yes. The AQUAvalve5 and its 3/8" fittings were specifically designed to handle liquid organic nutrients. The wider bore practically eliminates the blockages that plagued the older 1/4" systems. AutoPot recommends using their systems with AQUAvalve5 fittings for constant organic feeding. Earlier model valves with 1/4" pipe cannot handle organics reliably.
The PRO version includes an AirBase Round, AirDome Kit, and Propagation Dome for each pot. The AirBase replaces the perlite drainage layer at the bottom of the pot. The AirDome connects to an air pump (sold separately) and pumps oxygen directly into the root zone, which improves nutrient uptake and root development. The Propagation Dome fits over the pot and creates humidity for young plants during establishment.
That depends entirely on your reservoir size relative to your pot count and how much your plants are drinking. A single plant on a 12.4-gallon tank in veg can go well over a week. Four large plants in flower on the same tank might need a refill every few days. The rule is simple: never let the reservoir run empty. If air enters the lines, the AQUAvalve5 can lose its vacuum seal and stop reopening.
The XL pot gives roots nearly 70% more volume than the standard 3.9-gallon AutoPot. More root space means larger plants, better nutrient buffering, and less chance of the medium drying out too quickly under intense light. If you're growing in a 4x4 or larger tent and want to maximize plant size, the XL is the right choice.
Yes. Bottom-fed systems don't flush excess salts the way top-watering does, so maintaining proper pH in the reservoir is important. Target 5.8 to 6.2 for coco and hydro media, or 6.0 to 6.5 for soil blends. Check and adjust pH each time you refill.

Unbelievable!!!
Color: White, Number of Items: 1, Color: White, Number of Items: 1
First off, let me say wow! When I received this, I didn’t expect much because of the price, but I am blown away with the care that was given in the packaging alone, the simplicity of putting it together with the detailed yet brief instruction page, and the ability to put this together with one person. Took me less than 40mins. Highly recommend!!! And in fact, I’m purchasing another one right now as I’m sitting here rocking in my new beautiful chair. UPDATE: a lot of negative reviews are basically user error. To attach the wheels, to snap on, I used a rubber (not metal) mallet to tap them in. To the leveling review, you have one arm on backwards. To the screw passing through, you may be correct but double check you didn’t use the required screws elsewhere. And the person saying it doesn’t recline, you have to release the lock - pull the up and down lever out and away from the seat. Good luck all! Bought a second one - same thoughts as above. Pretty awesome chair.

Great aesthetic and easy assembly, but lacking in all-day comfort
Color: Orange, Number of Items: 1
Pros: Simple Assembly: It took less than 45 minutes to build. The instructions are straightforward, and all necessary tools are included. Getting the armrests aligned takes a bit of finagling, but it's manageable. Appearance & Shipping: It arrived well-packaged with no damage. It has a sleek, modern look that adds a great aesthetic to an office space, and the height adjustment works perfectly. Cons: Lack of Support: The comfort level falls short. At 5'11", I found the back offers no lumbar support, and the backrest isn't tall enough to serve as a headrest. Disappointing Armrests: The armrests are mostly metal with a thin, flimsy layer of faux leather. If you live in a colder climate or a poorly insulated home, the metal frames get quite cold to the touch. Limited Padding: The seat cushion is minimal. After about 3 hours of sitting, it starts to feel very firm and uncomfortable. Verdict: You ultimately get what you pay for. I would not recommend this as a primary desk chair for an 8-hour workday. However, it is an affordable, sharp-looking option if you just need a decorative accent piece, a guest chair, or budget-friendly seating for a conference room.

Recommend. Great for Home office
Color: White, Number of Items: 1, Color: White, Number of Items: 1
I am very pleased with this chair. I’m working on building my home office and it’s important to me and have a look that is comforting and clean looking the chair was easy to put together. Didn’t take very long at all. It’s sturdy. It rises up and down to fit your height and it’s comfortable. It was a great purchase. I’m glad I got it.

Seller Stall Tactics
Color: White, Number of Items: 1, Color: White, Number of Items: 1
My chair arrived last Wednesday, but I only assembled it today. It looks overwhelming as you take all of the pieces out of the box, but it is straightforward to assemble. Took me less than 45 minutes start to finish. Assembled, the chair is really nice. Many reviews talk about the incessant squeaking. I'm guessing it has to do with how they assembled the chair. Mine does not make a sound. The seat is very firm, it may be uncomfortable for some people; I'll have a better idea after I use it for awhile. I gave it 4 stars because the plastic lever to raise/lower the chair, the underside broke off in 3 pieces! Fortunately I was able to fit the pieces back, and used liquid Gorilla Glue all over the broken seams. So far it's holding up well. Visually the chair is beautiful. UPDATED 6/1/20 - I originally gave this chair 4 stars. As you can see in my original post, I took one star off for a crucial piece that was broken inside the box. I read reviews where customers who experienced issues were not getting assistance from the seller. I am now in that same issue. After I initially e-mailed the seller regarding a replacement part for that one piece, they are repeatedly e-mailing me asking me is this part broken, is that part also broken. My last e-mail to them stated that I have explained the issue in detail multiple times and if I am sent one more e-mail asking if another part is broken, I will know this is a stall tactic. I have an e-mail this morning asking if the gas lift is broken. I've contacted Amazon to contact the seller with the understanding that if they stall Amazon as well, a request will be made for a full refund. I am NOT the one to play with when it comes to shady customer service. If I could give negative stars based on the seller alone, I would.

Well made value chair
Color: Black, Color: Black
Great value and well constructed. Easy to assemble. It’s very light and maneuverable. It’s reasonably comfortable for occasional use although I would prefer something with more support if I were using this every day. For my needs, however, it’s perfect. Adjustments are easy – especially height, changing from tilting to rigid. I also appreciate the swing up arms, which was a feature that I particularly liked with this chair.
