If you are starting your plants from seed, you have many options for different strains.
But that’s a subject for a course all on its own.
If you are starting your plants from cuttings or clones, then you will be limited to what you or someone you know has available, at least as the current market stands.
At this stage most plants need a small amount of light, usually 18 hrs/day, higher than normal humidity and usually a medium suited for the next stage of the plants life.
We’ll get into that more a little later on.
A root hormone or stimulator is very useful at this stage to help roots get established before harmful bacteria can set in from the high humidity.
Once your seed germinates or your cutting has rooted then they can be transplanted into another medium, a temporary spot or the final place in any given hydroponic system.
At this stage they need more intense lighting and small amount of nutrients to help with preparing them for fast vegetative growth in a hydroponic system.
