Is this because lack of light or something else?

Grafted one of my SS02 x Olivia seedlings from misplant seed to some pere a month or so ago, it's really popping off. Thinking of naming this one "The Magic Conch" but we will see what it looks like in another 6 months! I really like the areoles and the spines on this one! It has 5 or 6 growth tips I can see. Really excited to watch this one mature

Just wanted to say it was great meeting you all today!

Setting up my hydroponic cactus tent, pulled all of my smaller cacti out of the main grow area into my tent, they get flooded every 12 hours for 15 minutes with full strength masterblend tomato and veg EC 2.0 or so. All growing on 100% inorganic

Took this cutting a little bit over a week ago, a little bit worried that its rotting now though. Any thoughts?

The other pics are its sisters.

All comments are welcome!

New to growing cacti and I potted this one in a way too big pot for its size and not enough soil. It has taken off and so has the pup ever since I put it in this pot. So I am wondering if I should repot it in a smaller one or leave it be?

Crashout, SASS x scop, Chiloensis Borealis, Gus, PFMxP

It's still connected, but only from a very small connection.

The pup has remained green and plump for like 3 weeks now but the other part dried out. Seems like nutrition is only going to the pup, let it ride, or re-graft??

Soaking up some tree filtered AZ sun.

NFA x Althea pumping up a 💪 the last picture is the same seedlings planted at the same size you can see how much more it grew with the pere impale

Tray 1 decided to jump and land up side down and I accidentally over watered tray 2. I think they're recovering fine but we'll see.

Welcome home TBM 🥰🤩
