Opinions about American Dream

and it's well suited to Hash making, according to you?
best for sieved hash, or water hash?

Well, this is the thing. If there were plenty of resin glands on the mature flowers, it's very difficult to understand why the buds would lack potency.

Resin glands are the most concentrated form of THC on the plant. If a plant produces resin, it's a sign of high potency (after all, it's possible for plants to be very potent even without visible resin), and there's no such thing as a resin gland that doesn't contain cannabinoid-rich resin.

Same goes for the smell, usually. A great deal of a bud's aroma comes from the terpenes present in and emitted from the resin glands.

The fact that your AD buds had no shortage of visible resin but a lack of potency or aroma suggests that something destroyed or severely degraded the resin at some point in the late flowering or drying process.

Were there any unusual or undesirable conditions in the grow area during the second half of flowering? We've had a particularly hot summer here in the north. How was the temperature in the AD's grow area?

How long did you flower these plants?

How did you dry these buds?

How soon after harvest did you first try these buds?

Also, when you say the resin was mature, does that mean you examined the colour of the glands with a magnifier prior to harvest? If so, what were the proportions of clear, milky and amber resin glands?

EDIT -  in answer to the hash question, I always prefer water hash to sieved, but either process is fine. A plant that's suitable for one method is suitable for the other.

The problem may be that the resin has been damaged, so while collecting and concentrating it should improve potency, if the dried bud didn't affect you, the hash made from it might also be quite weak.

Still, making hash is always a good idea, IMHO, especially if you don't particularly want to smoke the bud. I'd also be interested to hear if the hash is noticeably stronger than the bud, and also (assuming you use the water hash process) whether the best grade of hash bubbles when heated. If it does make nice-looking hash that bubbles and still doesn't have much effect, that would be truly bizarre.

American Dream can be more powerful than Skunk #1 when grown well, and it's definitely more potent than Ruderalis Indica.

I can't say I've ever seen properly grown and dried weed that had visible crystal yet no potency. And I've seen quite a lot of grows...

It seems definite that something went very long with your grow. Crystals = potency, unless something destroys the potency of the crystals during the growing or drying.

Did you grow the 'Moroc' as well?
