We are indeed thinking to release the purple haze in the future ... but it's not easy to breed with the purple haze pheno and guarantee a 100 % purple haze progeny, mainly cos the oldtimer's haze line is still enough diverse and is hard to find a good purple haze male.
The oldtimer's haze male ratio is around 5-10% and most of them will be green ... so you need to grow lot of haze plants to find the desired purple haze male. The new oldtimer's haze males are starting to flower outdoors but is still too hot outside for the purple color show.
