How often should I water my san pedro in the winter?

I am finding some conflicting info on the watering schedule for this cactus. I potted a san pedro cutting 4 weeks ago into dry cactus soil mix(indoor cactus northern united states). My instructions say to begin watering at four weeks. It is winter now where I live. I think i will give it a bit of water soon, but how often after that should I water it? Should I just wait until it looks like the ribs are sucking in?

Once temps start dropping below ~60F consistently I'd stop watering until Spring rolls around so your pedro will have a nice winter nap.

It has never been watered. I just potted it 4 weeks ago, so should I hit it with water once and let it hang out until spring or water it for the very first time in the spring?

No point in rushing to water it. If you water too early, it may rot. Your cutting will last a very long time without water. I have some cuttings I bought in March that still don't need water. Cacti can go without water for months, easily.

Now when it's winter and even I keep strong lights to cactus, still I show them it is winter by let them simply go very dehydrated before I water again.. Ofc my collection soil is drying faster but at winter time when days are short and so on, even you have cactus indoors at windowsill or something, you don't need to give much of water to trichocereus or you can keep plants totally without water for months, depends on temperatures.
You can spray small amount of water to skin at evening if it' not so cold at winter or spray to surface of soil small amount to let roots have water a bit but you don't need to water properly whole cactus before it's growing season or you don't need to water it at all.
If you have cactus under growing lights and temperature is good, then just water when soil is dry enough.
I do still now watering the way that I let plants really go soft cause of dehydration, then I water soil good and I let them again shrink a bit. I keep trichocereus winter dormant after december and only about 2month of dry and cool. I grow some species over december and start dormancy at january. My climate allow me to keep short winter later cause winter is very long and cold.
Peyote plants I have stop watering month ago and I don't give anymore excess heat nor water to them before it's sunny weather again.
Trichocereus I almost grow over year and cause of very short time I can even use greenhouse I have to use artificial growing lights for them to keep spring and fall season.. But they are easy to water.. Still there is possibility to get trichos rotting cause of watering so I advice to give at winter very small amount or not at all water, or give small amounts of water by spraying but not so often, only few times over the winter is ok, trichos can shrink a bit to let them know it's winter and they should not be grow. Some people will give trichocereus strong artificial lights over winter and rest of the year at summer keep them at greenhoue, some people give some dormancy for trichocereus.
I think it depends on climate much how you can grow your trichocereus. But even indoor cactus, no matter of species, I will suggest to give atleast 1-2month of dry and short day with possibility to let them have below +20C temperatures that time. Basically all cacti need some dormant if your plan is to keep them healthy for years and ofc whole growing cycle in a year triggers various things like flowering, possible offshoots and important of all dormancy are resting.
Acually some cobular echinopsis will bloom with big flowers indoors at windowsill in my climate without cold only by let cactus suffer 5months of drought and very short day(0-4hour) instead of summer they got sun and day leght are 20-24hours. Also some mammillaria species flower indoors there by let them dehydrate and have no long day but without shock of cold.
