Quote:
As far as I have learned, hydro roots are different than soil roots, so I will be experimenting with using fresh cuttings as well as pre-rooted soil grown cacti.



Peresk. Spathulata (and Hylocereus Undatus) cuttings can be made to grow 'water roots' by rooting in a Perlite wick propagator, like those popular with 'hydro' cannabis growers. The perlite is kept moist with multiple wicks which run from the Perlite to a reservoir of water. The Perlite remains damp, but allows for plenty of air circulation around the cuttings. The whole setup can be made for about $15 USD, using 2 tupperware dishes, a pack of Tiki Torch wicks, and a bag of un-ferted Perlite. If you're interested, I'll find the link for the design.

The Peresk. cuttings took about 25 days to develop 1" roots, the H. Undatas 32 days. The Peresk. cuttings were healthy, but the Undatus cuttings had tissue which was rotting -- they went from the propagator straight to the compost heap.

Awesome experiment!! Has it been working?? [Re: Cakes]
    #8030033 -

Greets Search59,

I hope this topic isn't dead yet. How did this little hobby turn out?

Being a newbie to this board, I'll introduce myself a bit. I am a hobby cactus grower. I've been growing Peyote and San Pedro modestly for about 4 years. I have 8 Peyote and about 25 San Pedro. Currently, I'm working in a hydroponics store in BC, Canada.

At our store, we have an aeroponics table set up that holds a variety of plants. Recently, we decided to experiment with San Pedros. For this little experiment - I cut 8 pieces of San Pedro and hardened them off for 10 days.

Our table setup is basically the same as yours. We have a bench with the aero-table on it, under the bench is our water reservoir. A pump feeds water into the table, and it drains back into the res. The difference between the two, is that instead of flooding our table and draining it, we have 1/2" 'PVC schedule 40' pipes running in the bottom of the table. The pipes have little spray jets in them that mist the water into the table(like the misters over vegetables at the local grocery store). We have a timer that mists for 30 seconds every 20 minutes.

Like your setup, we put a thick plastic top on the table, and cut holes for each basket. In each basket, we put Hydroton Lecca clay stones(lava stones) and one hardened off piece of San Pedro. Most of them were put in straight up and down, but I experimented and laid one down in the rocks, covering up most of it.

One of the advantages of this system, is that there is no actual growing medium. The roots don't sit in dirt or water. They hang in the air absorbing the water mist. This goes a long way toward preventing rot and enables you to water them a lot more.

It took about 3-5 weeks for the San Pedro's to start rooting. But, once they started, they kicked it up and knocked out quite a few long hairs. It has been a couple months now, but they are growing like none of the others I have. Sometimes I swear they are growing 1/2" per day. I would definitely think they like the hydro system better than dirt.

For light, we are using a 600W HPS Gavita bulb. I think this is a little bit overkill and normally I put my cacti under 54W T5 fluorescent lights. The lights are like normal fluorescents, but quit a bit smaller. They are much more energy efficient and quite inexpensive(look for 6400K or 10,000K).

I will post pictures as soon as I get a digital camera.

The cost of this setup is as follows.... We make the tables and plastic tops and sell a 2' X 4' set for about $180. You can make it yourself though for quit a bit cheaper.

Hydroponic water table 2' X 4' ---- $40
Coroplast 10mm Sheet Plastic 4' X 4' ---- $25
1/2" PVC pipe - 20' ---- $13
Spray Jets - 12 of them ---- $0.17/Each
1/2" Rubber Grommets - 4 ---- $0.50/Each
Various plastic fittings/hoses ---- $15

1/5 HP Little Giant Water Pump ---- $130
Arkal disk filter ---- $30
Timer ---- $40

3.5" Plastic bastkets ---- $0.35/Each
1 Bag of Hydroton Lecca ---- $20
========
$320 Approx.

You need a high pressure pump, not a cheap mag drive to power the misters. You also need the disk filter to prevent any fallen root material from falling into the res, going through the system and plugging up the misters. The pump is really the most expensive part, as you can probably build a table instead of buying one. Most of these items can be found at a hardware/irrigation store. Of course your local hydroponics shop will be able to provide you with all required.

Cheers

I do not think it will work but i have not nor would I risk cacti flesh trying. A hydroponic environment is not a cacti habitat (i dont care if your pump is on once a day for 5 mins). I think i might try growing some seaweed in sand/desert climate, you are basicvally saying the reverse of this not only would the roots system be in an detrimental environment but the excess moisture in your grow area would also be detrimental the the health of the flesh.

I have lots of experience growing other things in hydro, both in store bought systems and in home made systems in the style of NFT and Ebb and Flow or Flood and Drain as we used to call it(home made always better as you design it for your space). I could not imagine either working for cacti, especially not Peyote and Trichocereus, mine get wet about once a month if that.

Enjoy learning how to rot cacti and learning about what hydro does not work for (great for weed and any other plant that likes regular wetting of the root system) it sounds like maybe you were not listening when this part of hydro growing was explained at your class

This is an old thread but a novel idea.
At first, it's obvious that hydroponics and cactus won't mix.
But what if you let it dry out?

Flood it with dilute nutrient water, then drain it and let it air out until it's dry all the way through.
Cactus don't want or need soil, most would be happy growing in perlite or geolite if other conditions were correct.
Sounds plausible like that, yes?

Yeah i had a good think on that but the main thing made me think it would fail is the amount of airbourne moisture in your habitat and especially at the area where the nutrienta and root area is. My cacti seem to put all their best growth out a good month after they have had water, especially the Trichocereus, it is mid summer here and they have not had any moisture for over 6 weeks and they are loving it, the pots are light as a feather and the substate near powder dry but they are showing no signs of wanting liquid, maybe a bit pointless they being near a constantly ready supply of moisture and nutrient (i used to change my nutrient solution once ever 2 weeks to keep it fresh and wash out my reservoir). Also there is the theory that mesc producing cacti produce more mescaline when they are under duress especially times of no water in order to protect the source of water they hold in their flesh, in hard times the theory is they produce extra amounts of the bitter alkaloids and force them to the surface of the flesh to put off any wandering critter who takes a bite, so if they have constant nutrients when ever they can take them they will never be under moisture duress and ...... well that is if the theory is sound

My ambient RH is really low, I get spoiled by that.
I could just turn off the water and let it dry, but I can see that as a problem for others.
A month or more between cycles is fine really, and you could fine tune it as needed.

But sunlight and a clay pot is better.

Am I right in thinking that cacti alternate growing above and below ground?
That as water dries, they send out new roots. Then when the water returns, they absorb it and use that to grow above ground?
So really you want to let them go long enough they start to shrink a bit from water loss, this indicates they are growing roots?

As for alkaloid production, you could grow stress-free cacti rapidly, then turn off the water and let them respond as they naturally would.

Yup thats how i understand it. It is great when you got a big trich i like to bring it out of dormancy in april and then not water again until mid july, the growth spurt can almost be watched and that is under the power of my diluted 55 degrees north sunlight, must be amazing to watch closer to its natural sun strength habitat

So you want to decrease the watering frequency as you go along.
With little young cactus, water frequently, then as they get bigger let them go longer.
You could probably work out a schedule pretty easily.

I've got a San Pedro growing like you describe. I marked it with a sharpie marker when I got it and it's grown close to 2 cm in 6 weeks.
I don't know what's special about that one, but I'm glad it's happy.

Sounds good for this time of year.

Next year all my adult cacti are going to br brought out of dormancy in April with a little water then a week later a proper water to avoid splitting and then they are getting no more liquid until the next growing season (I do this every 5 years cos i believe the theory i mentioned above). I stated doing this because i read about 12 years ago that home grown Peyote were not potent and all the theories reasoning why this was were based on the regular supply of food and nutrients as opposed to in the wild where they have huge spells without liquid, I will be eating some 17 year old buttons soon so i will be able to verify if my home grown peyote were active or not

Just so you know, there are some people that have had success growing cacti hydroponically. All the cacti were grafted to pereskiopsis. They grew in test tubes filled with  mix of water and miracle grow fertilizer under led lights. The guys that do that call the method "HTTL" (hydro test tube loph). They say that they have been using that method for over ten years and they get massive growth out of their lophs. All there research, diagrams, and pictures are on Mycotopia.

I'd love to try this but I'm way too paranoid of cactus rot.  Is there any evidence that hydro/aeroponics would cause cuttings to root faster?
