what is a good price for this system used: Digital Greenhouse 400 watt digital ballast, Sun System 400 watt 1 mh and 1 hps light bulb and a HY Maxwing Reflector. Was only used for about 6 months.
I understand your point - there has to be an optimal size though - right?
I could put them in a very small box but then I would not be able to fit much of a plant in the box.
Let me rephrase - what would be the best box configuration for a newbie who has 2 105w CFLs?
