The experiment was carried out at the net-house of the College of Agriculture - Can Tho University and was arranged in Completely Randomized Design, with 6 replicates, including 5 treatments were 5 different substrate forms. Treatment one was a medium of straw, the other treatments were a mixture of rice husk: coconut coir dust by volume with the ratio 4:1, 3:2, 2:3, and 1:4. Experimental results showed that plants grew and flowered on rice husk: coconut coir dust (2:3) and straw substrates better than other treatments. Growth of plants in rice husk: coconut coir dust (2:3) and straw are similar
however, flower diameter when grown in rice husk: coconut coir dust (2:3) was larger than when grown in straw (8.82 versus 8.03 cm).
