GMSgrowsanswered grow question 2 years ago The lights will warm it up in the planters pretty quick. Use your lights when you plant. The seed will survive. Just make sure the pointed end gets planted upwards. Pointy end is where the tap root starts. It then does a u-turn and heads down into the planter while the seed head, heads toward the surface. If planted the wrong way, it then has to twist in the dirt and struggle to make it to the surface.
