So Lowryder has came out with a new strain called "Purple Jems"... It's the first auto strain I have seen that is purple.. Has anyone grown this strain? What was your yield? How did you grown it? What was the thc lvl if you had to guess? (explanation from cannabis-seed-bank.co.uk) Joint Doctor Purple Jems is a beautifully coloured new auto-flowering variety developed by underground breeder Mossy. Purple JEMS buds display a broad colour palette, ending with a stunning royal purple. A real pleasure to watch grow, these small plants produce large purple nuggets covered in a sticky layer of resin. The reward is a well-balanced stone that satisfies the palate and relaxes the body. Flavour is on the floral side with a hint of sweetness. Low ambient odour!
Wrong forum section, and wrong website in fact. You're looking for Google.com, and you want to search for "lowryder purple jems grow". That should answer any questions about the plant (if it actually exists) you have.
Purple Jems is a recent release, probably going to be a couple months before you find a grow journal.
