Help Growing Plants From Seed?

I order plant seeds online from online nursery. I ordered the following plant seeds. Morning Glory, Hemp Agrimony, Pion Flower, Valerian, and Wormwood. After the seeds arrived I placed all the seeds in marked plastic bags. Except the Morning Glory Since they are almost considered invasive weeds; and grow very easily. A week later I checked the bags and all had seeds that sprouted. YEAH!!!. I placed these into soil and misted. They all Died!!!! They seemed to have just wilted to death. Well I discovered the humidity was the main factor. So I Got to thinking,. I took an old fish tank and sealed it up. Placed The Hemp agrimony sprouting "the onyne currently alive now" in the tank. Hooked up humidifier to tank and pumped some moisture in. I guess you can call it a terrarium. I was wondering if the wormwood, pion flower, and valerian would grow nicely or even germinate in this. It is a ice mini green house that has alot of moisture.????? Any advice on germinating these plants .
