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?

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 havenโ€™t added any supplemental lighting beyond whatever the Tower Garden HOME version has. How do I fix this?

Food safe liner for 27 gal tote?

1 Upvotes

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!

Question โ” Hydrogen Peroxide rates for 2 gallon aeroclone units?

1 Upvotes

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?

Feedback Needed ๐Ÿ†˜ What herbs do I plant first?

Post image
4 Upvotes

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

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 didnโ€™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

Recovery๐Ÿ™Œ Wasabi DWC Midweek update (Day 6)

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 pictureโ€ฆ

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%

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 tomatoโ€™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?

Feedback Needed ๐Ÿ†˜ Making homemade hydroponic tower problems

Thumbnail

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!

Need Help Picking right material for 3d printing parts

1 Upvotes

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! โค๏ธ

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.
