 The first Trichocereus terscheckii I've found in stores now at home. At only 4 dollars I would have a collection of these if they were more common.
This was a simple experiment that I've been doing for 2 months now, this bridgesii seedling has been in water and has not rotted. This is similar to how some people do 'hydro' pereskiopsis. The new growth is visible in the photo. I use a hydro fertilizer and change the water once a month. I've done the same with astro seedlings but has not had impressive results, most has rotted.

Is that solution aerated?

Interesting....
Are you noticing significant differences between this method and the traditional? Did it have roots to beging with?

If trichocereus can handle more water than typical cactus, and you've got that thing in a jar of water without any aeration.....I might have to break out some of the old hydro gear and whip up a mini bubble bucket to put a few seedlings in and see how fast these things will grow.

Things would have to be pretty clean with a method like that. Why is the solution so brown?

Probably from the hydroponic nutrients, general hydro floranova nutes? What's a preferred NPK for cactus?

Higher in phosphorus than most other nutes.

No aeration; it is actually not being grown hydroponically but aquaponic. I change the water once a month since the 'air' in the water is likely depleted by then, There may be benefit from biweekly or even weekly water cycling but I'm not anna and changing that single water is already too much work once a month.
From my very limited understanding of why this works is because the new roots are 'water roots' and are structured differently than 'air roots' which are what they are in mineral mixes and soil mixes that dry out.

So then 4-8-7 floranova bloom would work for this little experiment I'm dreaming up? It's what I happen to have on hand.

Usually as far as roots are concerned, the big long ones are tap roots that search out water, the smaller side branching off of those are the feeder roots that look for food.

Science at its finest. I always wonder about hydro peyote. You think this would work on that application? Seems like a neat experiment.

Makes total sense and you can see the difference between soil and air roots in those pictures. They're like aerial roots grown in very high humidity environments.
I just wonder how it will cope over the cooler months. Wondering if it will go spotty or get some other bridgesii ailment that they're prone to. Cool stuff!

OOO thanks for bringing that up. This was actually a fresh cut and was not allowed to callous and placed directly in the water. Originally it was calloused with no roots and was placed in water. This caused some mold to form so I made a fresh cut and just let it be. The roots came in sooner than when it was calloused however I didn't have a control.

The solution is actually slightly blue due to the fertilizer. I chose an amber glass container to store the plant as I know that light damages roots. This is placed outside with all my other plants and get the same amount of light as normal plants.
After there are roots I leave a few centimeters between the water and the flesh to prevent rot.
This was simply an experiment to kill some time while I prepared for my new hobby... tissue culture.
This is a random trichocereus that I have successfully introduced in vitro. The first is about to pup the second is close to pupping and has callous the third has callous and the fourth has begun to pup. These have been in culture for 3 weeks now. For the first attempt I'm quite satisfied but have noticed I need to improve sterilization of the explant as 6+ of the 12 vessels have grown mold. 1 successful introduction is enough to get started experimenting. I'll be introducing a kk919 and another cv in the future and aztekium after I have the tek down.
I'm wondering if I should group my experiments in that chimera thread or make a new one all together. I won't have much to offer for weeks at a time so I think a new thread isn't warranted.

Yes that would work.

That would work and I've been meaning to set it up. This should work with ANY cactus. I would suggest you using a rooted lopho and trim the roots similar to how kada would do. The new roots can be left in water however the old roots and body CANNOT as it would rot.
Some people trim the roots of lophos as the tap root stores water but the thin roots take water in and are less likely to rot. You could trim the tap root and just start watering more often without as high a risk of rot. Some people think that bloated lophos are degrafts but I think its just trimmed tap roots and super bloated bodies.

I propagated my TBM crest cactus. Cut some section off what was going to grow underground almost. I grafted it to san pedro cactus and some time after, ta-da. My plant got burst of growth after I cut one actively growing section for graft.
I Love This Cactus!

 This have happened with many TBM cactus in my climate. Sometimes pup comes, stay small over one season and suddenly burst open when sun intensify over summer. Anyway, this had a nice growth burst when I cut active section off from another side of cactus and grafted it. I hope it takes now! Too many TBM crest grafts failed.
And I have already lost another TBM crest to rot, I've had two some times till one accidentally got some fungi when I tried to take scions from it. Now seems I have success with it.
This plant is on it's own root and I'll going to keep it that way.. I want massive, huge, hilarious own root TBM crest..
It's just a matter of time...

There's a firm grafted scion waiting to show new growth. It should take, just released pressure from it some day ago.

And some other common trichs waiting winter along others, mostly pach/peru/bridge plants.
 It's still +24-29C day time for cacti but it's because there is like +10C more warmer than usually. I've never felt so warm autumn here than 2014.

It's funny.. Trichs grow differently during mid-summer at 24hour light than spring/autumn when they are starting to receive light.. Usually it can be seen as thickness of cactus.. Most thick section is grown during mid summer when sun shines from north at mid-night. Even it's warm, I really should stop watering, in 3 months there are like 1-2hour sun plants need to be dehydrated fast to prevent 'em growing, also cold gives some benefits to prevent ugly etiolation happening, if so.. I cut ugly section off and let cactus grow new head at spring.

This is good example how fast sun changes position in sky and cause mid-summer growth be always more fat than other times of the year. Some south american pachanoi plants I received as 3-4inch seedlings or so.
 Every spring plants starts get fat and after mid-summer they starts to get slim again and don't grow anymore so big spines. There plants have got dormancy in dark and cool about 1-4months/year in my care. But I have moved 4 times during time I've had these two san pedros. Sun may change position in sky too fast for cactus and it's power reduce very fast. At spring it's very powerful because 1meter of snow reflects LOTS of light around.
But not bad about I have seen some columnar cactus plants in habitat may grow like that also in pictures. Slim winter section and fat summer section.
And that's the reason I need to end season earlier with trichs.. Sun just isn't so powerful anymore. I give my plants some 150W Metal halide light above them. It's not on every day, only sunny days and during autumn days. I just add it on at 9-10AM and shut down at 2-4PM. Light bulb just gives light from top so columns doesn't try to reach towards sun so much. I have now light coming from 3 position, two windows in corner of house and HID bulb above them.. It's very far away at ceiling(240cm) because it should not give heat during winter. Otherwise longest columnar tip is about 80-100cm away from bulb. Longer they grow, more they benefit from 150W MH light I have.
I was just wanted to light the dark spot at ceiling. I always use CFL/HPS/MH light with windowsill cactus, sun + some extra light is very powerful as indoor plant. I don't use more powerful light just because even 150W Metal halide light consumes 173Wattage of power. For cloudy and rainy days I have really think to maybe buy some 600W HPS bulb I can keep on when I need.
Anyway, most of the growth have happened without extra light, it's on like 2-6 days in week and only few hours. I have planned it's going to be useful when trichs grow taller. Fastest is my bridgesii, 14inch of growth for this year about 4-4,5cm thick.
During winter light can be on like 4-5hours and it doesn't heat too much because it's just 150W and very far away from plants.

Excellent project MS. Can you describe your aquaponics a bit more? I have a traditional aquaponics system with 350 gal fish tank and about a dozen ebb and flow grow beds. Do you have a seperate aquaponics system and just replensh your cacti's water out of that or something else? Im just curious as to what you mean by describing this as aquaponic
-------------------- One day Alice came to a fork in the road and saw a Cheshire cat in a tree. 'Which road do I take?' she asked. 'Where do you want to go?' was his response. 'I don't know', Alice answered. 'Then', said the cat, 'it doesn't matter.'
