Combos Plug & Play® Very Valentine Seed

Great germination rate!! Beautiful blooms.

I very carefully sowed the seeds as instructed on the package, in new sterile soil. The seeds germinated and then just stopped growing. I had the seedlings under lights and domed with ventilated plastic while they were starting, and they were in a warm protected place. I finally just threw away all the seedlings, that were exactly the size they were 4 weeks ago, except now they were yellow. Other seeds I started under the same conditions are all thriving. I am very disappointed and have no idea why I got such poor results.
