Try this:

 <table border='1'>
     <tr>
         <th width='120'>Production ID</th>
         <th width='120'>Description</th>
         <th width='120'>BOM</th>
         </tr>
 <?php
    while ($fetch=mysqli_fetch_row($select)) {
      echo "<tr>
            <td>" . $fetch[0] . "</td>
            <td>" . $fetch[1] . "</td>
            <td>" . $fetch[2] . "</td>
            <td><form action='AddProductMainEdit.php' method='GET'><input type='hidden'  value='".$fetch[0]."' name='prodid'><input type='submit' id='edit' value='Edit'></form></td>
            </tr>";
    }
?>
 </table>

You don't need to add the variable prodid to the url, the get method add all the variables to the url.
