Marylin, Be careful what you wish for! Are you familiar with the term "exponential growth". If today I have 1 semp that produces 20 offsets and next year those 20 each produce 20 offsets, then you will have 400 plants next year, followed by 8000 in year 3 and 160,000 in year 4. While 20 is a bit high for some of them, there are other varieties that produce many more than that.
You will have what you wish sooner than you think. (Ask Lynn, I think she is experience some of those numbers...) Can you handle 100k+ plants in a few years???
Remember the Star Trek episode "The Trouble with Tribbles"?
