I use a 320w led for veg and a 400 w hps for flower, I'm just wondering how it would go to use the led right through, really only just curious but I didn't want to waste a grow doing it lol, I'm in a 4x4 so thats how I do it. I then use
a CMH to finish with UV bulb but only in winter or cold times. Now even with an external ballast the operating temperature difference is at 6-7 degrees Celsius above ambient intake temperature so it's a no go for summer, hence the Hps is a necessary because even the led runs at 4-5 degrees Celsius above ambient but it's ok most of the time just within a couple degrees of automatic shut down, the fan cooled hps or mh is only 3 degrees Celsius higher than the intake temperature so this is a must to this setup and it's geological location. Then price of electricity is ridiculous so just asking for any tips. I didn't change over until week 2 in flower to try save stretch and power, it doesn't stop stretching lol
