WHAMRS54
WHAM Boom is a well-balanced indica/sativa hybrid strain that was created through the breeding of WHAM with RS54. The result is a strain that produces very high yields of buds with an extreme level of THC production that can approach 40%! Nicely balanced effects complete the picture.
Indoors, these plants grow to be up to 140cm tall providing yields of 600gr/m2 in a flowering time of 65 - 70 days. Outdoors, plants are naturally rather taller at up to 220cm. and produce yields of 900 - 1200gr/plant for early October harvests in the northern hemisphere.
The terps. are creamy vanilla and nutty. THC levels vary between 32 - 39%, an incredible figure. The effect is very well-balanced providing cerebral stimulation as well as powerful, physical relaxation.
