If you plant sugars as small saplings, plan on 30-40 years. Closer to 30 if you fertilize them and keep competition down, 40-45 if you just let nature do it without help.
Planting for tapping is generally done for future generations, but if you're young enough it can work for you. Go one better and get the super trees , then maybe 15-20 yrs can work, but they are not sugars, however they are very high sugar %. Maybe on real sugar maples, if you get a tree spade and transplant 2-3" caliper trees, and then fertilize maybe 15-20 years. A tree spade is a heavy piece of equipment that digs up the whole tree and carries it to a hole ready for receiving it that was dug by the same spade.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
