Still situational for me, otherwise I would have invested in good LED already.
Heat is what I generally need in my space. HID helps heat my space, saves watts and money on heating.
But, I shut the grow down for a couple months during peak summer, too hot.
There's also the price to consider.
Much of the reason why I haven't invested in quality LED to grow during summer. Not worth it for only 2 months in the year.
And, I really haven't the patience for DIY.
Can't beat HID if you want cheap but effective in my opinion.
Cheap vs expensive bulbs are fairly comparable too.
Whereas don't get me started on most cheap LEDs, worst grow lights in existence, lets be honest.
Such an exhausting debate LED vs HID.
My opinion, the efficiency debate is over, LED wins all day.
But, the price for quality units needs to come down. And will in time.
Which is better? lol
Carry on!
They both grow good plants all the same.
