I'm currently trying to grow papaver somniferum for the first time. Being from New Zealand, (and just beginning summer) it is till suitably cold for germination. I have sowed some in the ground and a couple in pots for my porch. I sowed the seeds about two weeks ago and as of yet nothing. For the pots, i've put plastic over the pots to increase the humidity, but my worry is that the warm temperatures created by the sun through the plastic will make it too hot for germination. Obviously, it's not hot during the night, but will the excessive heat in the day hamper germination?
