A provisional regime for growing containerised Douglas fir and Sitka spruce is descrbied. Seedlings are grown in a polythene greenhouse equipped with heating and ventilation. A plug-type container with a volume of 100-25 cc appears desirable. Growing medium, feeding and irrigation regimes are considered. The importance of inducing budset by drought-stressing or manipulation of photoperiod is emphasised.
