Hi i'm a new poster and first time grower and just need to ask a little questeon, if anybody could help it would be great I'm growing 4 plant's under a 600w HPS light, i'm pretty sure it's HPS? it's an Omega 600w Superlumen bulb and it give's of a sunny/orange glow, my first seed has just popped it's little head up and i'm worried I have my light to close/not close enough. At the moment it's about 18inch's away. My plant's are in seperate little potting cup's and I was planning on moving them in about 2 week's after the emerge into 12 litre growing bag's using Miracle Grow compost. Also any advice on watering my seed's would be great.
