I'm thinking about ordering a Yescom Grow light to keep seedlings going over the winter. The Grow Lights come in Red/Blue, Red/Blue/Orange, White, and other combinations. What color combo do you guys use?
This is the Grow Light:

Not sure what you're growing but I use the all white 225s and they work great for cephalotus, drosera, and pinguicula. They give out enough light to make the plants "blush"

Good to know, thanks. I thought there might be some benefit to using the fancy red/blue lights. White is convenient, I can reuse it as a bathroom light when I'm done.

I would say a heat mat is more beneficial when germinating seeds indoors. I did 3 batches this year, and all had a roughly 95~100% germination rate. I've only used a 2700k 90+ CRI cree bulb with a heatmat set at 84 ºf
my latest are some 1month 'A2' crossed with 'Jim Grant giant.' I lost most of the seeds due to a surprise shower, so I collected the few still attached to the seed pods and decided see how seeds would do in coco coir.

Very nice! Do you leave the light and heat mat on 24/7?

I have the light on for around 16hrs. I turn it on when I get up and when I go to bed.
The heat mat, I have it on 24/7 since it's a unheated room
