High Consistency

Good weed grinder cards come in handy when you need an even consistency for the vaping of the herb. Weed grinders are crucial in obtaining a consistent extraction of the important chemical compounds that are contained by the herb.

The flavour of the herb will be affected by the herb’s consistency more than the kind of vaporizer that is used in vaping The grinder cards ensures that the herb has been evenly grounded thus allowing it to burn even more consistently. This is what will result in a continuous flow of flavoured vapours.

Thick Vapours

During vaping, a lot of people tend to complain so much due to the absence of vapour clouds. Basically, most vapers prefer having large vape clouds. The truth however is that the manner in which the herb gets ground greatly determines other than the vaping devices being used. The texture of your herb will determine how thick the vape clouds will be.

Using a grinder card to grind your herb works magic in generating thick clouds. The use of grinder cards also guarantees a perfectly grounded herb that has strong hits and a better taste.

Intense and natural hits

It can be quite difficult to have the potential mixture of different chemical compounds available in the herb. Grinder cards however are able to achieve this with ease by ensuring all the herbs are evenly mixed.

Grinder cards are made with an easy way to fill in herbs. You should therefore grind the herbs consistently using the grinder cards. This will guarantee you richer flavours as well as thick vape clouds.

Trapping the kief

Kief is very important when it comes to the longevity of your herb. Kief forms part of the herb and is responsible for making the herb very potent. Using grinder cards will help you get hold of the kiefs which may otherwise have been lost if grounded using hands. This will also help increase the longevity of the stash.
