I lost the tiny floating indicator (the tiny red ball) when cleaning my 5 Gallon DWC set. Any idea where I can purchase the replacements (or are there any easy home-made alternative solutions)? I don't even know what size they are.

I've seen people successfully grow herbs using net pots or just sticking cuttings in the lid, and I was wondering for those who have experience growing them... if you have any opinions on either method or know drawbacks to either of them? For example, I would assume drilling holes and placing cutting directly into the bucket might damage the stem overtime as the stem becomes bigger and stronger?

I'm new to hydroponics and want to grow lots of basil and mint indoors with grow lights and just want to make sure I choose a good method since materials are expensive for me. Thank you!

Basically running one of those VEVOR setups that looks NFT but is basically modified DWC - there’s always water about half way in the pipes. I have been running the pump(out of approx 25L of water in the blue reservoir) for 5 minutes out of 60. I suspect the plants are not getting enough oxygen, and there’s a weird bacteria smell in the tank. Should the pump be on for more time?

Going to add hydroguard, do I need to add an air stone? I don’t think this will help because the air stone would be in the reservoir which is separate from the plants.

Hi All,

I am wanting to get started with aeroponics as a hobby and to have a fun activity with my kid but don't even know what I need.

I know I would like to go with a tower setup and would like to try make it myself out of PVC but I am not sure of the correct size.

With a misting system what size pump would I normally need if it was a 1.5m tall tower?

At the moment I have seedlings for lettuce, capsicums and strawberries as a test to see what will work well for me.

I am mostly trying to source the small stuff from Temu or Aliexpress to save on cost.

Any recommendations on parts are much appreciated.

I am located in Australia if that is important.

Thank you all in advance.

I'm putting together an RDWC system but am the paranoid sort and so am afraid it'll fail while I'm at work, flood & completely ruin my floors before I make it home and realize there's a problem... I'm looking into a flood tray (like pictured) to put under the 4 plant set-up in my tent and then a smaller one to go under my external reservoir outside the tent to hopefully save my floors if the worst does happen. The flood table has 7" sides on it, which will be needed in the worst case scenario, but my system utilizes undercurrent. Can anyone recommend a riser? or something durable enough to set the system on inside the tray so it sits high enough that the 7" wall won't be getting in the way of the PVC running to the external reservoir but that also low enough volume that if the system failed the riser wouldn't displace enough water to cause the flood tray to overflow rendering it useless? Or has someone else already invented a simpler solution & I'm just overthinking this?

Anyone have a recommendation for an app controlled timer? I need a new timer for my pump. Doing it at the outlet is always a hassle, so I’d like to upgrade to app controlled.

It should be able to be controlled to seconds.

Any recommendations?

Is this true?

I'm new to hydroponics and I bought a bunch of Masterblend Tomato Formula (4-18-38) then later decided I also want to grow lettuce and basil.

Is it really critical that I buy the Lettuce formula (8-15-36) for these? The lettuce formula has double the nitrogen, which makes sense for foliar growth. I have a 50lb bag of spray-grade (soluble) Ammonium Sulfate that I use for foliar application on my lawn, can I add the appropriate amount to the Tomato Formula to bump the nitrogen content a bit, or are there critical micronutrient differences between the two formulas?

Are you all custom nutrient home or commercial grower do you add only macro and micro nutrient only or also add amino acid, enzymes, biostimulant, growth regulated etc

I am making my first nutrient from scratch any recommendations what npk ratio should I making my nutrient from ??

And if any commercial grower want to help me start my trail aeroponic tower please I want a mentor . I have made everything from scratch and will be starting testing from tomorrow

Hey everyone, im looking at attempting to mark a 3d printed range of hydroponic items that will be available to purchase at somepoint in the future.

What i would like some feedback for what items that arent currently on the market that you would want to purchase or use.

My big garland trays contain 4 smaller trays. I have nft system setup but as the water follows itself towards one side or the middle, the water is uneven.

I want to add a divide in the middle to create 2 channels in the big garland tray. The only option I see is waterproof tape which I don't think would work well.

What else could be added as a divider to create two channels?

How good are led lights from Aliexpress?

I have this model and somehow I doubt in it as my tomato keeps to die in deep water culture.

Item name: LED grow light
Size: 3 head
Voltage: AC 85-265V
LED Quantity: 60 LED
Beam angle: 360°
Body Material: PVC
Useful life: 50000hrs
Plug: USB
Dimmable: 10 Modes(10% to 100%)
Timing: 3/9/12 hours
Switch: 3 Modes (Red, blue and mixed light)
Auto Memory: On/Off & Circular-Memory Timer
Adjustable: 360 Degree

This LED lamp has grow lights made up of 60 efficient growing LEDs. It meets the conditions of plant growth without sunlight. The red light promotes photosynthesis, germination, bloom and fruit bearing.

What do you think, is this enough for tomato plants?

I need something for home use, nothing big, so i tho this is perfect fit, but not sure if my plants like ti :(

When would you prune basil? Taking this picture as an example, which of the plants would you prune and where?

Basil, ready to prune?

So I am doing Kratky. I was advised by someone on this sub to switch from hydrogen peroxide in my nute solution (for prevention of bacteria and fungi) to beneficial bacteria, specifically, Southern AG Garden Friendly Fungicide. That brand is unavailable in Asia or in my country but I did find an equivalent, Monterey Complete Disease Control. My question is, for those who have used SAG GFF, how much exactly should I use per five-gallon bucket? I have read on here anywhere from one drop to 5ml per 5-gallon bucket. Someone said it should be 1 ml per bucket. Another said it should be 0.5ml per gallon, so 2.5ml per bucket. Another said 2ml per bucket is the sweet spot. Can anyone who has had success with GFF chime in on the correct amount?

My second question is, for those who have been using beneficial bacteria, whether GFF or Hydroguard or something else, is it okay to clean containers with hydrogen peroxide? Would that kill the bacteria even if I rinse out the peroxide before using the bucket?

Thirdly, how often do you reapply this? Or do you change out the nutrient solution periodically? If so, how often?

Has any one successfully cultivated saffron . Also what are the economics feasible to make it a business

I was checking my Bluelab combo pH and EC meter and the nutrient probe was reading 2.1 in a conductivity standard solution rated for 2.77. I cleaned the probe and tried again and I got the exact same reading. Then I tried it with a second identical combo meter and also got 2.1. Am I misunderstanding something here? Is this the reading I'm supposed to be getting? What are the chances both of my leaders are reading inaccurately to the exact same decimal point?

Edit: it just occurred to me I might be getting this reading because of temperature. The conductivity standard solution says 77°F but the water I'm currently testing is 85°F. Is that why they're reading low? I'm reading higher temps will cause the EC to go up, not down.

Are these air roots going to be harmful to the plant? AeroGarden is in a high humidity setting, in a greenhouse. Plant otherwise looks ok

This is my first hydro attempt, I am clearly struggling. Can some one help me identify my issue? Trying the Lucas method.

How can I grow strawberries in the tower garden? I would be growing from bareroot transplants. I have net pots inside my tower garden. Can I just put the bareroot transplants into the net pots? Should I clip them somehow to the pot, to prevent root rot?
