two people growing with sb420 exempt

[Hackk]

So here is a "hypothetical" for ya. If a person were to grow for their needs which may be "up to 99 plants" and another person were to also have the same allowance, could the two of them grow "up to 198 plants" in one garden as long as medical documentaion is posted? Not saying it would get anywhere close to that, but there is some contradicting information on CA NORML:

"The question remains as to how much medical marijuana cooperatives and collectives are allowed to grow or possess. According to the AG's guidelines, they can scale the SB 420 limits in proportion to the number of their members. For example, under the standard state guideline, a coop with ten members could have ten times the limits, i.e. 60 mature or 120 immature plants and up to 80 ounces of marijuana. However, some counties and cities have established a maximum cap on the size of collective gardens: for example, San Francisco does not allow more than 99 plants in any case.

In general, collectives are advised to exercise caution about growing very large gardens. Even if local guidelines permit it, don't assume that you can safely grow 600 plants just because you have 100 patients. Beware that cultivation of 100 plants or more is punishable by a federal mandatory minimum sentence of 5 years. Collectives are accordingly well advised to stay at 99 plants or less to reduce the risk of federal prosecution.
FEDERAL LAW"

And last question, if these two people were to share a garden, do posted medical papers have to be originals, or are photocopies acceptable? I figure copies are acceptable since dispensaries make copies for their legal documentation.
