KC42 is for the Sativa lovers and is a must for all connoisseurs and breeders. This one is a very special plant that has a lot of fine qualities and was rated as New Zealand's best weed. KC42 is a special haze hybrid by KC Brains with a reasonable Flowering Time: of just over 10 weeks its a pure sativa for those with just a little less patience.

KC42 has slightly unknown genetics that have most likely come out of South East Asia and Central America before they went to New Zealand. Expect tall growth with high yields and cup worthy buds for the lovers of all things Sativa. This one will take patience and care which might suit the more advanced growers that are hardened and ready to grow with passion and not for profit.

KC42 grows quite tall typically, depending on the technique used in your garden and grower ability. KC42 can be a little bit of a challenge to grow so slightly more advanced growers would be better suited for this one. Plants grow in a Sativa style structure with loose buds and thin fan leaves which is good for passing light around the lower buds. KC42 Haze can grow quite tall finishing up to 140cm so make sure you have enough room for them to flourish.

For the Sativa lovers KC42 will be a real treat that you will keep coming back to again and again. KC42 is a Cannabis Strain that is considered to have a THC content in excess of 25% which is very high and will be very potent. Cannabis strains with high THC content can have a very powerful effect on the mind. This can be desirable and undesirable depending on the individual marijuana users needs. THC is the main active compound in marijuana and KC42 with high content is likely to be more psychoactive and hypnotic and can be known for being a little trippy. Be careful if you are a novice as KC42 will make you forget your own name temporarily.
