Funny enough, started my hydroponic garden after watching The Last House on Netflix. Turned out pretty good so far.

From left to right: Bok Choi (2varieties), Albion Strawberries, micro tomato’s?(Red Robin and orange hat), 2 lettuce varieties.

Have another rack above with basil, parsley, bunching onions (which grow ridiculously slow), and more lettuce.

What do yous think?

Hi fellow tower growers.

I couldnt find any place online to get covers for my unused holes in my flow grow tower. The amount of algae was annoying me, so I made some.

If you too want some I have left the file in Thingverse it is thing number 7422307.

Sorry pictures are not great. I did it whilst I was doing a deep clean of the system.... because side quest i suppose.

Hey everyone,

I'm setting up a hydroponic system and running into a bit of a snag with my wicking.

Here's the setup: I've got a one-gallon reservoir with five holes for net pots. My plan is to use flannel as a wick to draw the nutrient solution up to the net pots, where my rockwool and plants will be.

The problem? The flannel isn't consistently wet at the bottom of the net pot. I've tried soaking the flannel first and then squeezing it a bit so it's not dripping wet, but I'm still seeing the water stop going up.

I'm wondering if the net pots need to be at an angle, or if there's a specific condition the flannel should be in. I did stretch out the flannel a bit when I was setting it up, and I'm thinking that might be contributing to the issue.

Any advice or tips on how to get good wicking action would be greatly appreciated!

I guess 28 plants in a 20 Gallon box are to many How many cells do you guys recommend ?

Hey, I'm getting into hydroponics and aquaponics, and I'd like to 3D print most of my parts. My main concern is layer lines trapping bacteria and making everything harder to clean.

I was looking into chemically smoothing PETG, but the chemicals needed aren't legally available for me to buy here (bummer, ik). So I started looking at ASA since it's more UV-resistant and can be smoothed with acetone.

The problem is that I've seen people saying ASA can release toxic styrene even after being left to off-gas for a few days, while others say off-gassing makes it safe. I don't know enough chemistry to tell who's right.

My main questions are:

• Is acetone-smoothed ASA actually safe for long-term use in hydroponic or aquaponic systems?
• Could it leach anything harmful into the water, especially for fish?
• Does off-gassing for a few days actually make a meaningful difference?
• Is there a better filament or finishing method for parts that will be constantly exposed to water, UV light, and possibly fish?

I'm no expert; I just don't want to accidentally poison my plants, fish, or myself lol.

Thanks to anyone who can help! ❤️

Bought some parts. Scavenged others that I already had.

I failed my first try (started too early without software updates 🫣) but this run seems a lot more promising! I’m seeing green everywhere. 🤗🌱 Welcome tomatoes! (There will be many, 9 pods on the left)

It’s a cool smart garden. Now sits in my living room corner and it’s looks don’t disappoint!

I'm building a free, open-source tool that watches pH, EC and irrigation sensors and suggests what to do. It never adjusts anything on its own; you approve or ignore each suggestion. It's early and I built it myself, so I'm after honest grower feedback, not selling anything.

What would make alerts like this useful to you, and what would make you ignore them?

Does anyone know why these dill plants get this reddish hue? Should I replant them or are they okay?

1g/l nitrocal, 1g/l campbells diamond white , medium coco coir
ph 6.3 ec 2.5

My strawberry leaves are all having these brown tips when growing and aren't producing a lot of new growth; does anybody know why this is?

I harvested all the peppers today, as the first ground frost is due this evening. The harvest amounts to about 2.5 kg of lovely, though partly unripe, peppers and about 1.5 kg of less attractive ones. The harvest comes from 2 plant.

I' m very surprised of this amount.

Will prob change this to weekly since there really isn’t much going on.

Update: gf made me these covers wrapped in tinfoil under with a small viewable portion to monitor aerator and roots in back. Very hard to capture via camera though so skipped it. No longer need to fiddle about with crumbled tinfoil after every update now, thankfully.

Root still look healthy, no visible rot today. Leaves remain healthy on first pic however, second plant still dried up, looking for new growth now for any sign of recovery.

Third picture, not exactly sure how to cover this one. He has a large root development system under, while I kept a majority under, couple remain in the air while I try to keep crown out of the moisture. Seems he has some partial rhizome development, even though it is very small.

All crowns remain firm and show no apparent sign of rot.

Stats:

EC and TDS remain stable approx 950-1000/450-500 respectively.

Temp last 12H - 62.2 F

RH 12H - 85 - trying to lower it very slowly to increase VPD during day. Not going below 85 currently though

pH remain stable now: avg all 4 - 6.04 - will leave them for couple days now alone as they recover more.

Odds of survival: No longer bleak - about 3% now. Will post next update either next Sunday or midweek!

It’s pretty cool what you can grow indoors 🍓🍓🍓

This is my second time growing thyme and it looks the exact same the first time but compared to google mines looks a bit stringy.. is this normal?

Looking for some ideas. I've ran enough hydrogen peroxide through this thing that my hands are covered in burns... I have my Sicce sump blasting h202 solution in cycle. Rised it out with hot water. Hit it with a Q-tip and its still pretty brown inside. I also did a baking soda solution through it. Any and all ideas are appreciated. I'd like to reuse the manifold if possible.

Over the past year or so I've been developing an aquarium controller, a device capable of monitoring water levels, checking for leaks and also watching values like PH, ORP, EC and TDS.

It's been developed for reef aquariums but it would be perfect for hydroponics!

To enable others to be able to build a controller like mine ive put the parts into a kit and today is the last day of the presale, if you would like a v3 controller please order soon.

The pre sale stops at 12:00 (GMT)

You can find it with a quick Google search for "marine assistant aquarium controller "

I have 2 plants in this 20 gallon reservoir. The ec is 1.5 and I plan on a water change tomorrow to get back to 2.2. The ph is 6 and has stayed in the optimal range. I’m using the masterblend formula. Any ideas why this plant is wilting? I have a lot of air feeding it but could the other plant be choking it out? The flowers are also real small and compact compared to the other plant

So last Friday afternoon, I adjusted my EC from 1.8 to 2.0. Then Saturday morning, I found this. I already lowered the EC, but just to make sure, I want to know if it is nutrient burn or a fungal infection? This never happened before and all my crops are affected. I even went higher EC before but this never happened.

The leaves are wet, I just sprayed organic pesticide this morning, since pest population are already increasing fast.
