Reference for Shabbat 255:1

אבל לא את הטבל וכו': פשיטא לא צריכא בטבל טבול מדרבנן שזרעו בעציץ שאינו נקוב:

BUT NOT <i>TEBEL</i>, etc. That is obvious? — It is necessary [to teach it] only of <i>tebel</i> made so by Rabbinical law, e.g., if it was sown in an unperforated pot.<span class="x" onmousemove="('comment',' Cf. supra 95a Mishnah. By Scriptural law it is not tebel at all, and one would think that the produce might therefore be handled. ');">¹</span>
