I stopped in the farm in Boulder this weekend just to see what clones they had, and they stopped doing them 'probably at least until Fall" which tells me it has to do with just what you mention - limits and 70:30.

Grateful Meds (nederland) seeds as well as Releaf (denver). You should call them to find out what they have before you roll.

from the CO constitution-
(i) "Usable form of marijuana" means the seeds, leaves, buds, and flowers of the plant (genus) cannabis, and any mixture or preparation thereof, which are appropriate for medical use as provided in this section, but excludes the plant's stalks, stems, and roots.

keep your business in-state & underweight and you should be okay. please double check my opinion with your attorney.

some other info to take into consideration-
Federal Law on Marijuana, Federal Marijuana Law - Marijuanahydro.com

Marijuana plants have three characteristic structures, readily apparent to the unaided lay person\'s eye: roots, stems, and leaves. Until a cutting develops roots of its own, it is not a plant itself but a mere piece of some other plant. We therefore adopt the rule that cuttings are not "plants" unless there is readily observable evidence of root formation. (U.S. v. Robinson [9th Cir.l994]35F.3d442.)

As part of the 1995 revisions of the federal sentencing guidelines, the Sentencing Commission defined the word "plant." The Commission essentially adopted the Ninth Circuit\'s definition as stated above in the Burke case. Specifically, beginning November 1, 1995, for the purposes of the federal guidelines, a plant is defined as:

. . .An organism having leaves and a readily observable root formation (e.g., a marijuana cutting having roots, a rootball, or root hairs is a marijuana plant.) (Sec. 2D1.1 Application Note 22, as revised.)

keep all of your business in state. that's one piece of advice that you can count on!!
