I'm about to try starting some Piper nigrum from seeds. I see this thread keeps popping up on the topic. I ordered some seeds online. I halfway expected red berry like seeds (ripened seeds, not fully dehydrated). What arrived was something that looked identical to black peppercorns from the spice bottle from the grocery store. The seller of these seeds says they are viable, so I'll give them a try. Other than warmth and humidity, are there any special requirements. I plan to soak them overnight before planting them. Is that a good idea or not? Then I plan to put them in small peat-pots with seed starting mix. I was thinking maybe mix in a bit of sand as well, and cover the seeds with a very light layer of just sand (about 1/8 inch or so, just covering the seeds). I'll keep those peat pots in a small plastic "seed starting greenhouse" that I have. To keep the humidity high in that, I was going to put some gravel on the bottom, and put a bit of water in the bottom. I don't want the seed pot sitting in water, because I'm guessing it wants drained soil/starting mix, but I also want the humidity high. I have a heating pad to keep the thing warm (about 80F, which should be fine, right?), and I'll have it under red/blue (mostly red) LED grow lights on a timer. How long do Piper nigrum seeds take to germinate? days? weeks? months?

Bumping UP! Here is your piper nigrum!

These vines are really picky about their environment. It's not an easy plant to grow. I agree with FataMorgana it could be any of those things. What are your growing conditions?
