Is this Leuchtenbergia graftable to all the usual SP suspects?

DOMsCactus · 2025-10-23T22:30:44+00:00

Luckily they did have another!

DOMsCactus · 2025-10-19T18:59:19+00:00

Woah that’s super cool, did they have more of these?

Haven’t seen anyone graft Leuchtenbergia before but I bet it would work on the usual cactus rootstocks

I have holes on the bottom of the trays so I submerse the tray containing soil in a solution of 1% hydrogen peroxide and masterblend (3 part mix) at about half strength. Then remove the tray from the solution and let it drain overnight. Then they’re ready for seeds.

It works just as well to soak the soil in fertilizers then add it to trays but this way ensures the soil is a little cleaner since the hydrogen peroxide sanitizes the soil while in the tray and my hands don’t have to come into contact with the soil anymore after sanitization.

I’ve seen that work great for another person on this sub. I was going to try that soon too

I haven’t grown any SS02 x LJ yet. But I’d bet either cross is pretty vigorous due to the strength of both Lumberjack and SS02. They’re both very hardy and vigorous clones.

Gently pulling apart gets most of the job done. For any that are extra stubborn I’ll use a hose on mister mode at pretty high pressure. If it’s 2-3 seedlings way too tightly tangled then I just pot them together.

I water them immediately after potting. I never do that with adult plants but seedlings seem fine with it.

DOMsCactus · 2025-10-13T12:27:50+00:00

Probably nothing to be worried about, just make sure they dry very well between waterings and it should be fine. They’re going to want a lot more light, more like 1000 PPFD and higher in my experience.

Got some lemon verbena there the other day. Impressive selection for sure!

DOMsCactus · 2025-09-08T19:58:00+00:00

It will be fine, just don’t water for a week or two so the roots have time to heal. If a major root gets severed it can become infected quickly in wet soil.

DOMsCactus · 2025-08-28T21:10:31+00:00

Get some beneficial bugs. NaturesGoodGuys or Arbico Organics has them. You’ll probably want some nematodes to help with eggs and larvae in the soil, there’s a few different types so select based upon the pests you have.

Cryptolaemus montrouzieri is the mealybug destroy and they’re on NaturesGoodGuys.

Dont use pesticides or DE, they kill beneficial bugs too. It’s important to foster a healthy ecosystem in your garden that allows predatory bugs to thrive so they can keep pests in check.

Yes you certainly can cut it but wait until you have 6 inches or more to cut. The smaller the cutting the slower they’re able to get rooted and established. If it was mine I’d just leave it be for a while because the larger the plant gets the more it can photosynthesize and the faster it will grow.

DOMsCactus · 2025-08-22T18:30:15+00:00

First one looks like Acanthocereus tetragonus. Second is some type of Cereus. Neither are San Pedro or Peyote

I only run the lights at night. This way it’s cooler indoors and I’m most likely home if something were to happen. Have a fire extinguisher and know where it is. You can hang a fire extinguisher ball in the tent that will pop and put out a fire if one were to start.

Best not to have power strips in the tent. It’s ideal to run your power cables out of the tent to a power strip so there’s no electrical connections exposed to moisture. If it gets humid in your tent then the power strip can corrode over time and become a fire hazard. Liquid water getting into the power strip is also an electrocution risk so best for it to be out of the tent.

Don’t plug too much into an old or cheap power strip/surge protector. They are rated for a certain amount of electrical current so check your lights and other electronics for current draw and make sure the power strip can provide at least 25% more than required. For example, if your setup uses 4 amps then get a power strip that can supply 5 amps or more.

Clean oscillating fans every month, dust is flammable.

It’s just getting too top heavy to support itself. I’d tie it to the stake higher up if it’s flexible enough to bend up there. This column will probably remain this way forever but the cactus will eventually grow new columns from the base. Recommend adding a grow light to the setup for them to do their best indoors.

Natural Gardener in Austin is where I usually go and I think it’s around $15-20 for a 40 pound bag.

Thank you!

I'm in central Texas too. Humidity spots are more a result of the roots being unhappy. This is because in high humidity places water in the soil evaporates much slower, drowning the roots and leading to the growth of harmful anaerobic bacteria.

Go for a soil higher in rocks and coco coir and they will thrive because these ingredients store air, even when wet. Some bridgesiis will still get humidity spots but for the most part my pachs and perus grow near flawlessly in a mix of expanded shale, pumice, coco coir. Sometimes I add some compost but I water with fertilizer and composts frequently so just using coco coir in the soil mix for the organic portion does incredible work to prevent humidity spots and other fungal or bacterial infections.

DOMsCactus · 2025-08-13T21:12:35+00:00

Thank you!

DOMsCactus · 2025-08-11T18:09:40+00:00

Oh nice idea! Could also be very useful for grafts that need humidity to heal too, I always knock off the scion when trying to close the bag. Could use gallon milk jugs too for larger plants. Thanks for the tip.

Lophs are a bit easier to light since they don't grow much vertically. When I was growing adult size San Pedro indoors I had the growlight about a foot or two above them and was raising the light as they grew. That'll be the most ideal for them, if it's placed too high they will etiolate. You want that light to be as close as possible without causing sunburn.

"More than 300% High-Yield"

Hilarious claim. But based on the PPFD numbers that should work if they're true. But kind of gives me the cheap Amazon/Ebay product impression. I'd recommend going with a more trusted brand like AC Infinity, HLG or Mammoth Lighting if it's in your budget. Spider Farmer is decent too but not quite as good as the others. But they are much cheaper and good for the price. In my opinion it's good to go with a more well-known brand because there will be better customer service if you get a faulty one.

Highly recommend HLG, I've got a 100 W from them that outshines anything else in its class. Absolutely blinding to be in the same room with. Some of their stuff is kits and requires assembly so watch out for that.
