assuming you know about germination, once the plant is 3/4 in high using 24/7 using 40watt flor's, then you can switch to 250 to 400 watt MH, still 24/7 until the plants start to show strong structure. Before they get too high transplant into 2 or 3 gal. buckets using high quality potting soil, vermeculite and perlite.(cheap at the depot)
Fans are good for circulation, water every 3 or 4 days with water you dumped into a pitcher and let sit for 24 hours to remove clorine. Don't worry about fertilizer yet, there is plenty in the potting soil. Depending on grow grow space, switch to 400 HPS light when you want to force your 5 plants to flower, Harvest when the white hairs turn amber brown. Hope this helps some, there are all kinds of variations to growing but one thing, from start to finish expect 6 to 7 months, be patient, be patient, and one more thing be patient.
