I have grown hundreds of your seeds at this point and now have more cacti than I know what to do with :) in a couple years I will be in a forest of cacti. Thank you so much for the tutorials.

Hi Jerry. Love your videos. But, you mentioned something that isn’t necessarily accurate anymore (possibly in Barcelona, but no longer in most of the US): Leaving tap water to sit overnight doesn’t eliminate “chlorine” if you live in an area that has switched to a slightly different form of the chemical. In the past decades most municipalities in the US (not sure about Europe or elsewhere) have switched from treating the water supply with chlorine to monochloramine (chloramine) which DOES NOT dissipate like chlorine. I learned this the hard way a few years ago setting up an aquarium. I did as I had done many years ago when I worked in an aquarium store. I had successfully set up countless aquariums and couldn’t understand why the new one wouldn’t cycle properly. Unfortunately, I put several innocent fish in toxic water before someone informed me of the chlorine/chloramine issue. I wanted to share this in case it helps anyone save seedlings or fish from a very common misunderstanding.

Just wanted to thank you for the cacti knowledge. Im brand new at this but 6 peyote seedlings i bought are doing great and even successfully sprouted peyote, bolivian torch and san pedro seeds myself. Keep up the great work buddy

Those seedlings are so cute

Very comprehensive and informative.

Such pro and complete info, respect and thanks from far, brother.

Im starting watching your movies and, wow!!! Tons of knowledge!!!

This is a great video. Thank you!

I really want to thank you for this video!

thanks for the updated video

so excited to get started :)

Great video 🌵 ❤️

Great and informative episode🌟🌟🌟🌟🌟

Thank you Sir.

Recently found you and Im learning so much about growing these i cant wait to start my 30 laphophora williamsii seeds

Many thanks :)

You definitely like to grow your strawberries! How did they turn out?

brother)) hello from Russia....thanks for the video!!)

oh thanks for the update"

What is your opinion on adding Mykorriza to the soil?

просто бог кактусов! уважение!

Hi Jerry, thanks for all your hard work. I have a little bit of a problem with seedlings, they are growing too slow. They only get about about 6 hours of direct sun light, unfortunately where I live I can't give them more. I bought these Peruvianus on Ebay arond january or february of last year, I think the oldest looking one (that is about 5 inches, maybe a little larger) grew somewhere about half an inch to an inch, all the rest of the seedlings remained very much stunted. It looks like finally they are waking uo from winter slumber, but they are going SOOO slow. I have them in pots large enough for three or four of them with store bought composted soil and perlite, about 50/50 mix. What could it be, not enough light? Thanks.

You don't want dust like material in your potting mix. It compacts and suffocates small roots hindering growth & promoting root rot. I always wash perlite as it contains so much dust. Also you should use higher fraction peat and sieve it removing dust. Doing so will increase oxygen at the root zone dramatically preventing any root rot and maximizing growth rate. It is some extra work but totally worth it. For my cacti I currently use 50% sieved peat + 25% washed perlite + 25% crushed granite, works great.

That's a nice plant at 9:36, how long does it take for a seedling to get that big?

Trichocereus cacti are my favorite. I have lots of Trichocereus Grandiflorus babies, they’re a year old and 5 months. They’re so fat

💚

How can I re root them? Just putting them in the earth? But WHEN should I water them if I re root them? Immediately? AMAZING VIDEO! Your knowledge is very impressive! 😊👍❤️🌵🙂

My seedlings are doing well; however they are noticeably leaning. Is this a indication of too much or little sun or water?

I did not like the amount of "composted forest products" in almost all of the potting soil I found. Some also had too much fertilizer. I bought 100% sphagnum peat moss to mix with the perlite and worm castings. I also have some "desert sand". Will the 100% peat moss be fine? I plan on doing the 50/25/25 like your video. Also, is this same mix good for larger 10-12 inch rooted San Pedro? Thanks so much for the videos!

Hi, thank you for this video. Can I use your mix potting soil (50%) perlite (25%), earth worm castings (25%) for san pedro cutting (25-30 cm long)? Can I use instead of potting soil, kera substrate for seedlings (without fertilizer, ph 5.0-6.5) and add the perlite and worm castings to the mix? What size of pot would you reccommand for this cutting size (25-30cm long cutting)? I have a square pot which is 11cm wide and 20 cm tall. Do you reccommand adding clay pebbles to the bottom of the pot when planting? When planting a cutting would you reccommand a bit wet soil (naturally wet) or bone dry soil and water when the cutting has rooted? Thank you very much.

Salut tu sais s'il est possible de bonsai un cactus? Je vais recevoir un peyote juste pour decorer et je me pose la question. D'ailleurs cela m'etonne que tu ne parles pas de PH dans cette video. Je croyais que les cacti preferent des sols plus acidiques comme les orchidees?

is that a GOA sample at the beginning (music clip on scene change) hahah :P

When you have many larger plants crowded into a small pot how do you get them out without damaging them.

Hey friend when you say regular potting soil made of peat moss and no additives do you mean I can use just pure 100% sphagnum peat moss? If not please give another example Compo Sana is unavailable

Not all tap water uses chloride. My municipality uses chloramine which does not evaporate from water.

I am new to growing san pedro. Last year my san pedro started growing something like root nodules/ spikes just above base of soil. Seemed like it was trying to get more water? Growing indoor under 1000w (1.5m from light, off to the side. 16hour days) I water more often now and that seemed to halt that issue. It has more than enough root space. Should I just leave it or what do you recommend. The SP is growing very fast and more than quadrupled, looks thick and healthy otherwise.

Pero vamos a ver xq hablas en inglés si los productos que compras los compras en español jajaja

Chlorine doesn't evaporate before water. You are concentrating it (the chlorine) by evaporating the water out.
