If it's just for one seed. 23 watt 6500k bulb will do. Just keep it 3 to 4 inches above the seed when it pops out. If you don't have a 6500k bulb 5000k will do. Best of luck with your grow.

That depends on how many seedlings and size of the space.

Should I wash the potting soil mix before sowing?
Going ahead with my first grow. Should I wash the potting mix before to remove impurities and dust particles, before I sow the sprouted seeds inside? The potting mix contains Coco Peat, Perlite, Organic Manure, Seaweed, and other beneficial microbes. Advice would be appreciated!
