The AutoPot Tray2Grow is a gravity-fed, completely passive irrigation system that keeps your plants hydrated on their terms, not yours. No pumps. No electricity. No forgetting. It uses a precision AQUAvalve5 to release water only when the tray runs dry, so roots never sit in standing water and you never come home to stressed plants. Whether you're starting seeds, running microgreens, or growing in fabric bags, the Tray2Grow handles all of it from a single tray. It's the most versatile product AutoPot has ever made.

Side by side
How it stacks up against hand-watering
Hand-watering / basic drip timers
- Requires daily attention. Miss a day and plants stress.
- Electricity or battery-powered timers can fail at the worst time
- Over- or under-watering is common without close monitoring
- Locked into one method. Can't switch between seed trays and grow bags.
- Nutrient runoff and water waste add up quickly
- Setup can be fiddly, messy, and hard to level correctly
AutoPot Tray2Grow
- Fully automated. Gravity and capillary action do the work.
- Zero electricity needed. No pumps, no timers, nothing to plug in.
- AQUAvalve5 delivers water only when the tray is dry. No guesswork.
- Five watering methods: seeds, microgreens, pots, grow bags, coco slabs
- Closed-loop system minimizes runoff and dramatically cuts water waste
- Spirit levels and grommet fittings included. Levels perfectly every time.
What makes it different
Built for how growers actually work
One tray, any growing method 5 methods
Seed trays, microgreens, small pots, grow bags, coco slabs. Switch between capillary spikes and capillary matting to support any setup without buying a different system.
Zero electricity required
Gravity does the heavy lifting. The AQUAvalve5 uses a simple float mechanism with no pumps, no timers, no batteries. Nothing to fail during a heat wave or a power outage.
AQUAvalve5 demand watering
Water only enters the tray when it runs dry, not on a timer. Plants drink what they need, when they need it. No standing water. No root rot from overwatering.
Dramatically less water waste 50% less water
The closed-loop system recirculates unused water back through the valve. No runoff trays to empty, no nutrients lost down the drain. Just efficient, targeted delivery.
Gravity-fed from any reservoir
Connect to one of the included FlexiTank options or hook straight into your existing reservoir. The tray sits below, no lifting or pumping required.
Compact, bench-ready footprint
At 44" × 16.2", the Tray2Grow fits standard growing benches, rolling racks, and grow tent shelves. Spirit levels and all hardware included. Level it once and you're done.

How the system works
1
Fill the reservoir
Water (with or without nutrients) goes into your reservoir. Gravity pulls it toward the tray. No pump needed.
2
AQUAvalve5 takes over
Once the tray runs dry, the float valve opens and lets in just enough water to fill it, then closes. No timers, no sensors to calibrate.
3
Capillary action feeds roots
Spikes or matting wick water up into your substrate, bottom-up on demand. Roots stay consistently moist without sitting in standing water.
4
You just refill the tank
The system runs itself until the reservoir is empty. Check it every few days. Refill less often if you sized up to a larger tank.
Questions
Frequently asked questions
Yes, and it's probably the most beginner-friendly automated system we carry. There's no programming, no app, no schedule to set. You fill the reservoir, connect the tubing, level the tray with the included spirit levels, and you're done. The valve handles everything else. Most growers have it running in under 30 minutes. We also have the full setup PDF and if you get stuck, call us at 716-217-0353 and we'll walk you through it.
It's designed for outdoor use. The tray includes an overflow plug that prevents the tray from filling beyond a safe level, so a heavy rain won't drown your plants. Fabric grow bags drain quickly, and as long as your substrate has decent drainage, you'll be fine. We'd still suggest going with a 25-gallon or larger tank outdoors so you're not refilling constantly in warm weather.
That depends mainly on how large a reservoir you choose. For seed starting and microgreens indoors with a 13-gallon tank, most growers refill once a week. If you're running larger fabric bags outdoors in a hot climate, you may need to refill every 2–3 days with a 13-gallon tank . Or move up to the 25 or 60-gallon FlexiTank for true set-it-and-forget-it coverage. If you tell us your setup we can give you a better estimate.
Both work fine. The system is fully compatible with liquid nutrient solutions. Just mix your nutrients in the reservoir at your normal dilution rate and the valve delivers it to the tray on demand the same way it would with plain water. The included golf filter helps keep particles from clogging the valve. Rinse it periodically, especially if you're running thicker solutions.
Here's a practical guide: If you're primarily doing seed starting or microgreens indoors and can check on things every week, the 13-gallon FlexiTank is plenty. If you're growing in multiple bags outdoors in a warm climate, or you want longer intervals between refills, go with 25 gallons minimum. The 60-gallon FlexiTank is for larger operations or anyone who wants to set it and check it once every week or two. When in doubt, size up. A bigger tank never hurts, and you can always partially fill it.
Both are included with the standard kit. You get the capillary matting for seed trays, microgreen trays, and pots, as well as 10 capillary spikes for grow bags and soil bags. You don't need to buy accessories to get started with any of these methods. The only additional items are the optional microgreen trays (4-pack) and the raised planter box, which are add-ons if you need them.
If you receive a defective or damaged unit, email us a photo at [email protected] and we'll make it right immediately: replacement or refund, your call.

Excellent Epson, worth the investment!
Style: ET-5800, Set: FAX/Print/Copy/Scan
First, this is a big printer so double check the measurement specs before purchasing if space is an issue.
First impressions: very well built, especially comparing to ET versions such as the ET-4800 ( see my review on that one for details).
This is a sturdy printer, you can feel it when you lift the scanning bed, pull out the paper trays, etc.
Printing quality: excellent right out of the box. I didn’t need to do an extensive alignment or cleaning during setup, everything printed perfectly and was photo quality.
Setup was easy. Although it has a fax feature, I don’t use that so I didn’t need to set it up.
Printing: using the rear paper trays, it prints on 100lb card stock very easily. I recommend only loading a few pages at a time to avoid any issues. I loaded 5 pages and made prints without any issues.
65 lb card stock was also easy to print on using the back paper feed tray and I loaded 8 sheets without an issue but know it could probably handle a few more. Just remember that the thicker the paper the more chance of having it jam with multiple sheets in the rear paper try. AND, only use the rear tray feed for cardstock or other thick paper.
The actual paper tray drawers, there are two and you can set them up for different sizes and types of paper, very convenient.
Now the cool detail: most printers have a flimsy plastic slide tray to catch the prints as they come out of the printer. Not this one. This has a really amazing tray catch that comes out of the printer automatically (it is motorized), and when you are done there is a little illuminated icon on the screen that looks like the printer, you press it and the tray retracts. Pretty cool detail.
The screen: very easy to use and you can actually see it, unlike the postage stamp size screen they used in the ET-4800. All features are very easy to find and select and the icons are illuminated. Using this screen, setup was very easy.
Ink: again a very good feature and very well thought out. The bottles are keyed so they fit in the receptacle. Simply unscrew the cap, tip them over (they won’t spill or leak) and place them in the correct color, the bottles automatically fill the tank. When done filling, remove the bottle and put the cap back on, again they won’t spill or leak because they have a mechanism that prevents it from doing so.
Overall: excellent printer, expensive but over time the ink savings alone help ease the sticker price. It is heavy and sturdy, has wireless capability so you can put it anywhere and print with ease connected to your wireless network, has the ability to print from android and IPhone with an app, and it has amazing prints.
This is one printer I highly recommend.

No more expensive ink cartridges
Style: ET-5800, Set: FAX/Print/Copy/Scan
Great printer. I am sick and tired of HP giving me problems with their ink cartridges. I discarded my HP office Jet and replaced it with this Epson printer. Easy to set up. Came with two sets of ink bottles. Easy and clean to fill tanks with ink. The screen on my old HP Office Jet printer was so small and difficult to use. This Epson printer has a very large LCD screen which can tilt if you want and very easy to use. Separate paper trays for letter and legal or other sizes. Print, scan and fax. Connect via cable or WiFi. I wish I had purchased this sooner.

Error handling is extremely poor
Style: ET-5800, Set: FAX/Print/Copy/Scan
This printer will throw errors even though things are working. Some examples are:
1) Printing from an Apple device you will get a “printer busy“ error, even though the print goes through.
2) When connecting to Wi-Fi, the printer will send a “password incorrect” error message, even though it connects to the Wi-Fi.
3) The windows desktop application cannot find the printer, even though you can print to it from that same machine.
When calling Epson for Support, you will find people who insist you do things like go through the WPS procedure even though you tell them your router does not support WPS. You will be forced to go through steps until they say something like “now press the WPS button on the router“ when they will agree with you that your router does not support WPS. They will also take you a very long way to get to a ping command because that is what their documentation tells them to do, even if you’re well aware of how to start a ping in a much quicker way.
Print quality and speed seem to be very good but, at this price point, the error handling issues and lack of adequate support are unacceptable. The result in a lot of frustration, wasted time and wasted paper/ink.

Very nice and fast printer, but some info...
Style: ET-5850, Set: FAX/Print/Copy/Scan
The printer is nice and very fast printing regular documents in color or black and white. Printing photos is slower but still pretty faster than other printers I have seen. The model I purchased was the ET-5850, it came with 2 sets of full size ink bottles. When you set up the printer one set will fill the tanks. You think run through setup on the display and it will take 9 minutes to prime the system. This is initially getting the ink from the tanks to fill the empty tubes to the print heads. When this is done (takes 9 minutes) the tanks will be ½ full. Good thing you have the second set.
The size in the images shows the depth of the printer to be 31 inches, it's not, it's about 19 inches with the back tray closed and the output tray retracted.
Installing the driver way very simple. I did not use the driver disc as I'm running the latest OS on my computers. My Mac's all found the printer and set them up. (Note: I run in dark mode on my computers and when the driver installs it as the back version of the printer for the icon we is very hard to see in dark mode. I was able to change it to the image that matched the color my printer, but that takes some under the hood tinkering.) Both of my Windows computers also found and set up the printers without any issue.
You can also set up an email address for your printer that people can email you documents to it. The Epson website gives you a lot of control over this. You can change to a custom name before the @ in the address or use the random one they picked. You can also limit who can send to your printer. That is something that I liked on my old HP this one replaced.
Two items that I think they need to fix:
The output tray comes out automatically when you start to print. It does not retract automatically, there is a symbol on the control panel that you tap to get it to retract. They should have made it so that when you take what was printed that it automatically retracts as it sticks out pretty far.
The web interface isn't great. If you have ever used the web interface for a commercial copier, then you know what I mean. For example, when putting in contacts for faxing/scanning/emailing, the interface doesn't allow you to put in email addresses. There is an option to select the type of contact, fax, email, etc, but if doesn't give you a box to put in the email address. If you add the entry on the display for the device its self then you can put in the email. You can then go back to the web interface and edit the entry and the email address. Crazy right. Luckily I didn't have many to put in.
If they could five those two items I would give it 5 stars. I'm going to email Epson my thoughts and see what happens.

Really Great Printer!
Style: ET-5880, Set: FAX/Print/Copy/Scan
I purchased the Epson ET-5880 for our small office to fulfill our need for a good color printer. I read a number of a reviews about the printer before making the purchase. Most were positive, so I went ahead and ordered the printer. I'm very pleased with this printer. I had no problem connecting it to our network. Installing the drivers on four computers was easy as well. I should note that the printer comes with a CD for installation, but I chose to use the NEWER drivers that were on Epson's website instead. You should do that as well.
Filling the ink tanks on the printer was very simple. Not so much as a drop of ink was spilled. The ink bottles are keyed so that one cannot put the wrong color ink in a tank no intended for that color. Once filled, the unit goes through a charging process (Epson's term) to get ink to the print heads. Yes, it uses a little ink, but Epson also supplied a second set of ink bottles so that the ink tanks are full after the charging process. The printing is very fast, yielding high quality print. I suggest using 22 or 24 pound paper, especially if printing on both sides of the paper.
I was particularly interested in seeing how this printer would handle scanning. I do a lot of two-sided scanning. The scanning software, SCAN 2 and SCANSMART, both worked well. SCAN 2 gives the user lots of options, but might be overwhelming to a newer user. The SCANSMART software is more visual and gives the user enough features to adjust and/or crop images as needed. The software does provide the option of creating a searchable PDF file, which is something I like as I deal in contract documents. Of course, one can print from a cell phone or tablet if desired. There's even a remote print feature where one can print via email from anywhere where there's an Internet connection.
Overall, I'm pleased with this printer. It's not inexpensive, but it will easily meet the needs of a small office.
