If I got two mars 300 lights could I go from germination to harvest with them

Yes, starting high with seedlings (follow what the manual says). But the lights themselves should be fine for veg and flower.

Those should be fine as long as it’s enough light. But the spectrum shows veg and flower.

Think you’ll be happy with the led lights less heat
I need to run a heater in my tent to keep temp at 76 day and 67 night
I own like 6 now and plan on getting higher wattage lights soon 
I use another brand but it’s all good
I was going to go with yours but the mars would be cheaper @Countryboyjvd1971
All good we all have a budget to work with I’m sure you’ll have good results with them 
When you start a grow journal tag me in cuzzy
Will do

Question from a fellow grower:
How big of a led light do I need for a 60x31x80" grow tent and ?
Hey there hope this helps
At the formula of 30watts per square foot of good quality led you would need a unit that draws about 450watts from the wall, that would be 30watts sq/ft and fans for cooling the unit.
Not 100% on which ubit would be best for the persons situation
Hi
I’m just about to start my first ever grow, done a lot of reading and I think I’m now ready. The one thing I’m still a little confused with is the lighting, I purchased a king led light just wondering if anyone can let me know if it’s up to the job ahead? See photos and spec
Any advice would be appreciated
