wow! a spike, planifolia? is it from crown grow point or from side node on newest growth?, you are very very lucky to ave one of those so early and in a home location. Usually the vines vigorous vegative growth, with high humidity demands, with many o many meters of spread with maturity thrown in only consider such a decision. Lets see what the majority say! Even stem cuttings from a mature vine auto resume juvenile status and primary veg growth objective. Decided to forward mine on as space an issue and my dove orchid wins that one.
