If you want THC effect, decarboxylize the product at a temp of 315 degrees Farenheight but no higher than 319 degrees F. If you want more cbd effect go up to 356 degrees F.
I would cook the dry weed until 315 chopped up, to cook evenly, in the oven for a few minutes after reaching the 315 degree level. no more than a couple of minutes or you risk over heating it.
Then it wont matter what temperature you use when you filter as long as it doesn't goi over 315 again.
Kindred Spirit has a thread on it, it is called "decarboxylation temperature boiling point of cannabinoids, tupenes, and flavenoids" in the medical sec tion.
Hope this helps you,
