A technology for the propagation of giant bamboo by using intermittent mist clonal propagator was developed by the authors. Findings showed that the mist provides a cooling effect and the cyclic (intermittent) misting provides a controlled environment of low temperature and high humidity, which favors root and shoot development of cuttings. Survival rate for one-node culm cuttings reached up to 80% compared to only 20% for branch cuttings. Under a glass house (or shed), propagating beds (1m x 8m, uncovered) filled with pure sand medium were used. One-node culm cuttings of D. asper were prepared and dipped into root hormone solution. Each propagating bed was equally divided to accomodate the cuttings. Automatic misting cycle was set at 10 seconds on and 5 times off duration. After 60 days, the seedlings were placed in polyethylene pots filled with ordinary soil and then hardened in the nursery from 0.5 to 1 month. Propagation of 300 prices one-node culm cuttings for 2-2.5 months will encur P6,100 and P9,000 for inputs and labor, respectively. Sales of 250 prices of giant bamboo seedlings (assuming 80% survival rate) will have a gross income of P25,000
