Hey, I just started my first grow w/ just 3 bagseed plants. My current setup is the plants growing under only 1 20 watt flourescent for veg and then a 75 watt hps for flowering. My main question is should i veg under the hps cuz its more efficient than the flourescents even tho its not exactly the rite color for veg? or if sum1 wants to give me instructions on how to modify my hps ballast to run mh bulb, that would be great 2.
i got from the ballast red, blue, and black wires.
From the ignitor, red, white, and blue.
And from the socket is white and black.
Anybody no of how i could bypass the ignitor?

just get a 75 watt metal halide bulb and stick it in to your hps ballast it works but not recomended for prolonged use

I know that this isn't what you want to hear, but buy the appropriate ballst for metal halide or just veg underneath the HPS, It may not be ideal but it works all the same
