I grew Diesel Ryder a couple months ago. From the ten seeds, I grew two of them the first round. One was male. One was female. I just left them next to each other and would occasionally pick up the male and rub it around on the female. They were in small pots, so it wasn't hard to do. I got plenty of seeds from that first plant.
I grew all the rest at once. Six of the eight survived, and I think two were male. I separated them for about a week and then just rubbed them around on the females I wanted pollinated. I only left one little runty one unpollinated.
They all took just over two weeks to show sex, and then about 6 to 7 weeks to finish flowering after that. If I remember correctly, seeds take about four weeks to develop, so you've got about two to three weeks from the beginning of flowering to start knocking up the females for seeds.
Even seeded, they still smoked quite nicely. All of my friends said it was quite good. I've got two growing now from the seeds I made. One looks to be male, and since I have plenty of seeds, I'll probably kill it. It's still early though, so I might let it go another couple days just to be sure.
