Our most Afghan derived automatic, 24 Carat holds a special place in our hearts as she was the first ever Mephisto Genetics completed Product. She was designed to be our new higher quality Auto-flower Sea of Green Strain, which means great yield potential and fast turn-arounds of really nice quality meds. She has a High flower to leaf ratio and high yield relative to the plant size.
We selected a beautiful example of Sour Boggle from F2’s we made., hard buds, waxy green leaves the size of dinner plates that will purple under cooler temps. Ultra frosty and hard nuggets, with an indica/highly medicinal effect she’s now nicely stable at F6 and has been used to create many auto to auto hybrids and a new Artisanal strain in development.
Bushy, thick and squat structure which results in a plant 40-60cm. Responds well to light training and leaf tucking early on. The fan leaves can be so big it’s worth removing a few to encourage lower shoots. Internodes are tight. 24 Carat is an easy plant to grow, that doesn’t want for much, she just gets on with it. Maintain a low humidity in mid-late flower, and ensure good ventilation to prevent mold.
Better suited to indoor unless you have a very arid outdoor climate. She is a great little hash-plant for the extract lovers out there, She is super easy to process and the trim is well worth utilising.
