Softwood weight loss over time

[hawk eye]

I've got some Douglas and larch to potentially fell this Autumn with it probably going for biomass or firewood mid summer next year. Will it loose much weight by then (don't want to loose to much ££s on the weigh tickets), I've got some free time to fell now or should I really wait till spring next year?

Sell by the cube. Last lot of douglas I got was sold by volume

Typical averages of increase in volume/weight ratio to be expected between felling and weighing of 20 days for unbarked timber:

Spruce and Douglas fir April-Sept +7%, October-March +1.5% 

Pine & larch April-Sept +5%, October-March +1% 

Decline expected after 70-80 days as drying cannot go on indefinitely. 

Rate of drying influenced mainly by weather but also to some degree by dimensions of timber.

I lost out one very hot/dry summer because of delay in moving fencing products and chipwood from roadside.  You can of course sell by volume but many will only deal in weight as their system is set up for that.

are they not big enough for saw logs?
