same here CMH was so cool in the winter i needed a electric heater in my grow space... ive had great results with CMH for veg/HPS for flwrThe heat is actually a selling point for me. If I used all LED I’d have to go buy electric heaters for my grow - which is totally ass backwards.
Where I’m looking from they seem a lot cheaper. A 315w CMH is $250 Canadian and a 275 watt quantum board is $780 - neither including taxes and shipping.
Ha ha I don’t mean to be the guy in the corner here contradicting things. Different situations and needs. But quantum boards to me like they cost almost three times as much. Cheaper if you DIY parts of them of course- but still expensive as hell.
