Stages of plant growth:

There are 3 main stages to plant growth that will apply to us here.

Seedling, or clone/cutting

Vegetative growth

Flowering or Fruiting

Seedling, or cutting stage:

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.

The vegetative stage:

This is where plant growth really gets going.
It still amazes me every time.
If all of the conditions are right the plant will now grow tall, green and full.


With the lights still on for 18 hours/day you will begin to increase the amount of nutrients that you are feeding your plants as well as give them maximum amounts of blue spectrum lighting.


Within 2 to 3 weeks the plant will usually grow to at least over half of the height that the plant will end up being in the end.


Another great thing about playing god is that you get to decide how large you want your plants to be by manipulating the conditions.

One of them being when your plants changes from vegetative growth to the final stage which is flowering.

The flowering or fruiting stage:

The light at this stage is usually set to a cycle of 12 hours on and 12 hours off. No light whatsoever should be available to the plants during their night time.
You also get to choose this depending on YOUR schedule.


This is where light begins to take a large part in helping to determine what your plant do.
At 12 hours of darkness the plant is tricked into thinking that the end of the season is near and so begins the end of the life cycle.


Again, depending on what you want the plant to be used for, it could be manipulated into either flowering where you harvest the flowers, or where you pollinate the flowers to go into seed production.


The plant will need again need a change of nutrient formulation.
More of some nutrients and near zero amounts of others.

More on this later as well.
