Yes.
Also, using this post to make a simple explanation into the seeds.
Attribute seeds are divided into two stages: Lesser, and Greater. Lesser seeds are much more common, but also provide smaller boosts. Greater seeds are rare but provide larger boosts. It takes 5 lesser seeds to match 1 greater seed. A single greater seed provides +1 to a stat, but too many seeds can lead to a resistance to their effects. Every time you increase a stat, you need to add +1 greater seed (or +5 lesser seeds) to increase your stats to the same effect. Seeds of skill can only be used fully grown. You gain +2 points to use and do not need to increase consumption to gain the same amount of points.
