Thank you my friend! There seem to be more comments about that monster than anything else - certainly a centrepiece in my collection! Yes, about grapefruit-sized, I would say!

Thats Great Mircea! Keep on looking like a cactus lover my friend!

Exactly my friend lol

It really is! There's no excuse for not giving us a few months of flowers at this size!

You're so lucky! You can literally find these fantastic plants on your doorstep!

As salaam u Aleikum and Eid Mubarak! No my friend, we're basically using 4 sizes, thee sizes of square pots 2 3/4", 3 1/22 and 4 1/2 inches and then some big round pans (about 20cm/ 8" for the bigger specimen plants) !

@@kirkstonebotanicalsforgrow5424 - Your are using: 1. 2 3/4" X 2 1/2" 2. 3 1/2" 3. 4 1/2" X 4" What's the fourth size?

Walaykum Salam. I am going to do the same as it's good to keep things simple. Your Gymnocalycium collection is amazing. Thanks.

@@alhashimi786 Mash'Allah - simplicity is always the way forward - Insh'Allah your collection will grow from strength to strength!

@@kirkstonebotanicalsforgrow5424 - InshahAllah / Thanks. What's the fourth square pot size? Plus what do you use as an insecticide for anything that affects the roots?
