First of all welcome to AFN, glad to have you here. You might want to stop by the introductions section and introduce yourself to everyone so we can get to know you a little bit. Now as for your question I don't know exactly what you mean by "sensi" is that short for sensimillia meand no seeds or the breeder Sensi seeds. But either way I have been growing cannabis for almost 10 years and have never heard of a strain or type that did not require curing.
Curing is the process of letting the starches breaking down into sugars after the plant has been harvested and dried. So technically you don't have to cure any strain or type of buds but if you don't the chlorophyl will be the only thing you taste and the smoke will taste like fresh lawn clippings.
Curing is probably the most skipped step in all of growing if you ask me, people are so excited that they make it to the end of the product and think that is it. But if you want any kind of real smell or taste to your smoke you will go through the proper steps to dry and cure it. Hope this helps! And happy growing
