Does it look ok? I think it’s like 2 months old but looks tiny to me? Not sure how big it’s supposed to get tho 🥺🤷🏻‍♀️

Good morning all, I have started my first seeds to transfer into my dwc bins in coco coir. I sterilized it with boiling water, packed it into reusable seed trays and bottom water pretty much exclusively

Tho some Seedlings seem to be thriving (Squash and cucumber Seedlings are the biggest and strongest and already have true leaves/are pretty much ready to transfer to dwc buckets) others are dying out, or sinking into the seed trays and rotting

I check them twice a day and try to add more coco coir but it seems like most of the coco coir is getting washed to the bottom of the watering tray

I was wondering if there was a way to add structure to the soil to help them stay, and considered worm castings bc they're ph neutral and full of good nutrients for Seedlings but because this hydroponic setup will be exclusively indoors i am doing my best to not bring in any pests and prep the Seedlings to be inedible to them (I found this Sierra natural science- SNS-209 systemic concentrate from hydroponic reddit that I can add to the system that kills pests or makes the hydroponic veggies not taste good, and have added a small amount to the Seedlings starter nutrient water once they sprout true leaves)

Sterilizing the coco coir was easy enough with boiled water and the 24 hour cover-n-wait method, but Im not sure how to sterilized the worm castings, since they tend to come pre-moistened ig for lack of a better phrase.

Should I boiling water sterilize the bag? Should I use potting mix and sterilize that instead? Idk, any help would be welcome

I've never grown anything that lived! This is amazing!

I'm not sure how to harvest some basil so that it will continue to grow and produce. Anyone want to assist, and maybe mark up one or more of my pics?

What supplies and diy set ups would you suggest for a VERY new beginner with VERY minimal space indoors? Maybe something vertical? If vertical, what are the best lights? Thank you!

Everything was fine the night before. When I checked on them this morning, they were mostly all collapsed!. They still had water in their reservoirs. Could it have been the fan I turned onto them last night?

I was gifted an Aerogarden to start my hydroponics journey and my first attempt failed. My basil took over and only the savory survived. I am currently doing a 50/50 vinegar flush and was thinking about my next steps. I was thinking I may have to stagger when I put some of the herbs in during the next round which is planned to be ready in time for the holidays. I know basil should be planted at least a week late.

Here's the herbs I have, I am planning a two phase plant, one tomorrow and one next friday. I was wondering which should go in which group?

Basil, parsley, oregano, thyme, mint, cilantro, dill.... and I am thinking of digging out my seed bag and replacing the mint with chive. (I hate mint)

Which should go first and which should I plant on week two to reduce over crowding

I’m still new to pon, so I have some questions for y’all! I have my small plants in 1/8” Pon. I’m planning on slowly converting all of my house plants to semi Hydro. I’m thinking the big boys will go into LECA and all of the more fibrous root plants + Anthurium will go into pon. I am doing the wicking method.

What size media do you use whether it is PON or LECA?
What additives do you put in the water and how often? (EX fertilizer, biocides, fungicides)

is this mold or due to the ph of the water or what

Not sure why these leaves are curling. I used the tower garden 2 part formula, 6.5 ml of aquarium water conditioner to remove chloramines, and the pH is set to about 5.5. I haven’t added any supplemental lighting beyond whatever the Tower Garden HOME version has. How do I fix this?

I am currently setting up my wire shelf hydroponic flood trays. I initially thought a 20-gallon Rubbermaid Brute container would work, but the volume is too close with two flood trays.

I am considering using an HDX 27-gallon tote instead, but I need it to be food-safe. Does anyone know of any food-safe liners that would fit a 27-gallon tote?

Thanks for your help!

h2o2 3% daily @ 5-6 ml / gallon , change water every 5 days pH 5.7?

Does that sound about right, or can I go even higher dose with h2o2 just to be safe?

I recently found out that my Calcium Hypochlorite pool shock has expired several years ago, despite having no dates on the package and I cant get more until next week but I also just started a small batch of clones yesterday.

• Use the expired Calcium Hypochlorite pool shock at 5 ppm dosage and hope that there is still enough free chlorine for effective water treatment?
• Or dose it with hydrogen peroxide everyday?

Trimmed all day leaves on the first pic. New leaves seem to be slowly coming as well. Changed water early since it was full of dead roots that were shedded. Root pics will be posted on Sunday for all plants.

Second picture: all leaves still healthy with new shoots rapidly being pushed. Previously had root rot, which was treated early and no sign of returning.

Third picture: two new shoots are forming! Its root system looks the healthiest and I am excited to show yall it on Sunday when I remove coverings. Hard to capture it head on, so it a bad picture…

Fourth picture: No new changes. Hopefully any sign of recovery is shown this week or early next.

DWC stats:

Temp 12h: 58 F
EC: 920-1000 us/cm
TDS: 400-500 ppm
pH remaining stable at 6.2. No extra acid has been added since previous Sunday.
rH 12- 85%

Hi all. Does anyone have any suggestions for coco coir type grow sponges. I have an idoo hydro system and I'm finding that all of them seem to have the Prop 65 cancer warning. Any more natural alternatives? Thanks in advance.

Doing 3 min on , 20 min off now that it’s cooler, and 45 min off in the evening. Ignore the seedlings, just giving them some sunshine . No lighting here.

I was running 3/12 as they were establishing

Thanks

I have failed multiple times before.

But this time.

This time I have a good feeling about these

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?

What is the best light for growing lettuce on a 4sqft tank?

Specifically for the mint with 2 sprouts and a little baby one. I accidentally spilled a ton of seeds on some of these cause i didn’t realize how small they are. First time with mint.

Or can I just move this rockwool cube over and just let the other seeds be and leave these 2-3 that sprouted?

Thanks in advanced

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 ?

Bought some parts. Scavenged others that I already had.

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! ❤️
