What is the best grow light??
Hi!! I just bought a 5 foot by 6 foot by 7 tall portable greenhouse.. One with the green cover.. I live in Eastern Washington State, zone 6 and want to start seeds in it and also bought a heat mat and starting trays with plastic domes.. We still have 12 inches of snow on the ground so I plan to put the GH on my covered deck which gets about 9 hours of light but no sun.. I then plan to move the greenhouse to my garden area when the snow melts and I can prepare a good spot for it there.. I get about 6-8 hours of sun in the garden area in spring and summer.. My question is: Do I need a grow light in the GH to start seeds and if so what is your recommendation as to the best one for it?? We are currently having a late winter and it is in the teens.. I was thinking of putting an oil filled heater in there also to keep the temperature up.. Any advice will be greatly appreciated!!! Thanks Pat Collins

If you get at least 8 hours of sun, then you likely won't need a grow light. If you just want to provide enough for seedlings, then you really won't need anything more than a T5 panel. You really don't need a whole lot of light for seedlings, and outdoor light will usually be plenty.
