spraying 2-3 times when it has 13-14 leafs
spraying 2 times to all parts
of the plant during 15-30 days before harvest
make the plant higher, increase the amount of leaf
spraying to the face of leafs when it has 5-6 true leafs
make the leaf bigger, obviously increase production
spraying to the face of leafs about 10 days before harvest
accelerate growth of the plant, bigger the leafs, increase production
drop at the tail of flowers when the plant has 70% flower
few shatter, more fructification, early ripeness
spraying to young cuke when young cuke grow to 3 inchs
bigger the fruit, early reapness
spraying 3-5 times during 2-3 days after reap
elongate and bigger the area of the leafs, increasse production
spraying to the face of leafs at 10 days before harvest
accelerate growth of the plant, bigger the area of the leafs, increase production
spraying to the flower at the beginning of florescence to blooming
spraying to little melon, once time every 6 days, total 2-3 times
accelerate growth and increase production
spraying to the flower at florescence
