Holidays

I was taught many years ago in yeshiva that precut wooden sticks sold in hardware stores are not kosher as schach because they are cut to shape and are not in their natural form. I use bamboo mats for my own succah. This year, I spent the first two days of Yom Tov out of town and stayed with a rabbi. I found he had built his succah using these long wooden sticks as his schach. I brought this up with him. He told me that many rabbis do consider wooden sticks unkosher, but he poskins that they are permitted. While I stayed with him for these two days, I had no access to any other succah. I am on my way home now. But for future reference, what should I do if I find myself in this position? Should I follow what I learned in yeshiva or the rabbi of the small community I am visiting? Should I refrain from reciting leshev b’succah in what according to what I learned is an unkosher succah? Should I refrain from eating all foods that require being eaten in a succah during my stay?

Is an etrog which had it's pitom broken off during chol hamoed kosher for use on chol hamoed?

What makes a “megasukkah” kosher? These extra-large sukkahs, designed for large communal gatherings, have support structures as part of their roof that are made of materials not kosher for schach. Many of them have pieces of metal running across the middle of the top in order to hold up the bamboo mats (or other materials) that are not available to match the total dimensions of the sukkah.

Hello About the Sukkah, I know when they're supposed to go up, and how long they have to stay up, but I can't find any direction for when they should come down. Are there any rules I've missed, in scripture or elsewhere? Thank you

Dear Rabbi, Can you please explain to me the mitzvah of the “four species” and what’s special about it? Thanks!
