Athosanswered grow question 4 years ago You are confusing two different things. The harvest time affect the maturity of thricomes (clear, white or amber). White thricomes are at their peak THC content while amber thricomes have a more sedated effect and degraded THC. While clear Thricomes have a more head effect, you will not be able to get a sativa effect out of an indica strain. Indica or sativa effect depends on the strains genetics
