I have one loph in a sunny window sill- it has not been watered in several months and is doing fine. i wont water it again until my house is over 80*f

"About the grafting, I really want to practice with that but I only have big diameter san pedro's and torches, which probably are way to big for grafting a peyote onto. I was thinking to cut one of my new pedros and leave 10 cm at the base to put one of the biggest lophs or one of my clusters on. In all topics I found on the net about grafting larger lophs on pedro they all seem to match in diameter. Most topics are about seedlings on periskiopsis."

big pedros work best!

it might work of to graft at the base of a pedro- but the tip is better. in fact the pedro doesn't even need to be rooted for the graft to take and start growing

the scion doesn't need to be as large as the stock- the inner growth bundles just need to overlap in one spot.

as for the miticide- anything effective in killing mites can be so termed....cinnamon included it it works

^these guys have a ton of good info/products

i've seen experts on other sites recommend dilute methanol for mites of sensitive cacti.

if you use an oil base product(they work great on mites) be sure to keep direct sun off the cacti for several days or they will burn
