I went to another local nursery today and was surprised by the amount freaks they sold, had a bunch of grafted crests and variegated columnars as well as some massive TBMs... I searched around online to try and find some answers but everything seems pretty confusing and people seem to mix A and B up. I was told A is the long type and B is the short multiple branching TBM, correct me if I'm wrong. My question is this, does a TBM 'obese' version exist or are they just selling very fat clone B pups as this? They were larger than any I have ever seen personally, small football sized almost.... I held off on picking one up since I was a bit suspicious and they were a bit pricey, I wish I had snagged a picture. Going back next week to see some larger cacti they get in Monday so I'll take some pictures then. I did happen to snag a nice sized TBM clone B for $5 that had 5 segments just because a couple of blemishes There were also 2 massive TBMs (clone A I think?) for $100 each that had between 3-5 large segments, I thought they were well worth it for the size but didn't have $ so I'll get a picture of those too and see what type everyone thinks they are.

I have some 5 year old trichocereus bridgesii that I sadly haven't repotted in 4 years. The tallest ones in the picture are about 53cm. This year will be a good year for them because not only will they get a new large pot (or pots) but they get to leave the 4 year old store-bought cactus soil mix I used at the time! I'm thinking 1 part garden soil, 1 part pearlite (or pumace) and a small amount of sand for the new soil mix. My question is this: I was thinking about burying them about 10cm deeper than they are now, which would put the thin 1st year of growth under the soil and hopefully make them more stable (see picture with drawn lines and text). Not only is the bottom of the cactus thinner than the top but a few of them are also leaning at the bottom then they curve up to vertical at the top. Is this a bad idea? Will I rot out the bottom? I live in the cold north of the US so they've been grown indoors and have a pretty controlled environment. I'm also hoping by mixing my own soil this time it will be better draining and not rot out the newly buried portion.

Hi peoples. I have decided to get back into old hobbies and this site helped me out LOADS years ago. Ok long story short I am looking to buy Echinopsis pachanoi, peruviana, and lageniformis seeds. Also Lophophora williamsii seeds. I think one slow growing species of cacti is enough... I want to have a go trying to sow seeds instead of cuttings, I think this would be a much more rewarding experience. Although if I have a hard time finding seeds then I can be happy with cuttings. Also I rather buy from users here as I don't trust some sites honesty with the species they provide, plus I figured its better to support people here that can put the money to better use. Please and thank you!

Today I sowed my first seeds. I purchased them from SAB as Ech. Lageniformis x Ech. Peruviana 'KK1688' and sowed 12. I used a cactus soil mixed with about 50% perlite. Unfortunately the perlite wasn't as coarse as I would have liked. I then mixed and added some water before sterilising in the oven (100C) for 20 minutes. I purchased a small seed germinating box which should help increase humidity with spraying. I added my soil mixture to each of the 12 sections and then bathed the base in water before putting the potted area into the bottom covering. Next came the most exciting sowing. I sowed the seeds by just placing one in each section and then lightly misting before covering the germination box. I have sat it outside but out of direct sunlight. I may consider changing its position depending on temperature and sun. I still have enough seed to retry if I fail. Any advice welcome. I am very excited.
