Happy Hydroponicing!
Tuesday couldn’t start better… keep going Hooch!!!
*Important tip: Do not freeze de plants😅
it’s like you read my mind, i’ve been looking for large glass jars but might give this a crack instead!

I have one kratky grow every year (4yrs now) in a 20L styrofoam box I got from the local fish market.
I don’t have any of the water testers you have but I’ve never had any issues. Well only one and it was the rain overfilling the container.
I only have two plants usually if I’m growing leafy greens like lettuce or silverbeet. One plant if I grow a tomato. My box during the grow, sits outside in the garden in full sun.
My main problem is there’s no hydroponic shops within 300km, so I have to really plan what I’m going to grow.
Posting 20kg bags is off tap costs and Bunnings wants to sell you bottles of solution water. I have a problem paying for water.
I’ve recently found a chemical Ag company but they don’t sell everything nutrient wise.
Where do you live?
@Hoochoup in Mackay mate. Nearest shop is Rockhampton and Townsville
I had the same problem with peppers in an AeroSpring once. I let the monitoring slip for a while and wondered what the plants grew weirdly and had thrips. Turned out PH was 4.5 and EC was way over two.
I am monitoring regularly since and counter the EC by topping up with low EC tab water while adjusting the PH with Silica (up) or enzymes (down).
Maybe try 1 plant in one 2 plants in the other but the one with 2 connect it to a float valve
Hoocho, with all due respect, I think the reason you run into issues with a lot of your time lapses is due to the lack of Magnesium and Sulfur in your nutes, you just use White + Calcium nitrate. Also I realized that the Campbell’s white has low micros, especially iron.
Do you not add any epsom salt? If that’s the case then that might be the reason because the Campbell’s stuff barely has any Mg and S.
Be interesting to compare a variety of plants with different nutrient brands – eg Canna etc which is supposed to be pH stabilised etc. Seems diamond white does have 1.9% sulphur and 1.5% magnesium.
Yeah but those Mg and S percentages are not enough for hydro@afmedwards
yes he is missing campbells solu-mag for sure. Also diamond white is a mid ground not good at anything ok at most. In lettuce it produces tougher lettuce and more leggy lettuce. needs to go back to diamond blue for greens.
Or something leached out of the silicone. They can often produce acetic acid when curing. That could have been the cascading event
Thanks Hoocho
is there any bufer solution you can add to such a small system?
🔥🔥🔥🔥🔥
Thinking back, didn’t the Kratky literature say something about 4 L per lettuce?
Less plastic ≠ no plastic
Can’t wait till you start working with Hemp lol
Try topping them up during the process.
Try this: Cut a hole into the lid (3cm diameter) and tape it with Micropore for controlled air exchange. With the ‘classic’ Kratky Method the upper parts of the net pots allow air exchange. The silicone lid sits so close around the stem which doesn’t allow any air exchange. So the ‘air roots’ consume the oxygen in the hermetic box. The CO2 concentration increases relatively to the remaining mole cules in the air of your box. That causes the CO2 being pushed into the water ( it wants to equalize the difference in the concentration between air and water). The chemical reaction:
Co2 + H2O -> H2CO3 (carbonic acid). Ph drops dramatically in your nutrient solution. That’s my guess.
Love the time lapse videos!
Here I was thinking initially there was room for 3 plants🙄
AWWW they only ship to australia ? w h y ? ? ? dont do this to us Hoocho. Call them for us please. ask them to talk to a courier and set DDP shipping with them. (for the tariff, but thad depends on where they actually make the trays, and customs)
I saw others being very successful with the kratky method using a small aquarium air pump with an airstone. I think the sealed silicon container takes the plants the needed air and then you’ll see anaerobic decomposing going on
