The drawbacks of starting with clones can prove to make the entire growing experience a wasted effort. Clones will incorporate any diseases, pests, and genetic weaknesses of the mother plant into your crop.
Also, clones shipped through the mail will arrive in a state of shock, adding two to three weeks to your growing process, if the plants survive. It could be argued that the time lost in recovery equals the time to sprout your own seeds and grow them to the same stage as mail-order plants.
