Damn 65 is cheap. I usually pay 75, but yes I prefer hortilux.
ultra sun, plant max....$30/1000w for each bulb...replace bulbs after each run or every two runs....all brands have roughly the same initial output and their intensity degrades over the same period of time (in most cases)...and with how HPS bulbs work, after 6 months of usage, you'd be lucky to be pumping 2/3 of the lumens compared to when new...So, basically, you should be replacing your bulbs, regardless of brand, every 2 runs...That's where the $30 bulb makes a huge difference...good luck
I will second that, you can run a plant max in a digi ballast with no worries too
I'm trying to get them for 65, shiiiit
Plantlightinghydroponics has digilux 1k MHs for 54.90. I have one right now, on a used magnetic, and holy shit is it bright. Brightest MH I have seen. I dig the color output as well.
Those Gavita hps are supposed to be best at PAR watts by a fair bit, even over hortilux. But they are all red, so they must be balanced by a blue light to the canopy as well.
Hortilux is supposed to have better par watts than digilux, I do not like their prices.
