Step 4

After 48-72 hours all that are going to germinate are likely to have popped their heads above the soil. Those that don't in this time period can be kept a while but I write them off after a week. If it doesn't germ in a week I don't want to grow it anyway.
For the next week or two these babies are in their seedling stage and are pretty delicate.

Their crucial things to look out for during these stages is over watering, heat and fertilizing too soon. Your plant does not need to be drowned and the soil should be slightly moist no more, conversely your seedling cannot hold much too much water so you do not want them transpiring (water exchange through foliage) too much, to avoid this keep them under flo's and avoid undue heat.

At this stage (and all stages) you should have some air exchange around the seeders to start strengthening the stems and to maximise the CO2 available to them.

Turn on those fans brah but only gently, too much air movement will increase the rate of transpiration (water loss) in the plant and soil.

Use 18, 20 or 24 hours of light.

I like to keep seedlings under fluorescent lighting until it is 8 to 10 inches tall. This is about the maximum effective penetration of fluorescent lights. Flo's provide a gentler less hot light source that can be positioned closer to seedlings than a HID.
