Lay unrolled flax bags on wire mesh after well washed and dried. If plants are very small, there should be no spaces between pots. If plants are not small put a space of 2 inches between two adjacent pots.
Water plants until drain from bottom. Watering plants should be done after 4.30 p.m. using watering pot. Do not water at rain seasons. Lay refuse of coir beneath the wire mesh and keep it wet always.
Fertilizers must be use before 8.30 in the morning and do not use in rainy and not shiny days.
