Hi, I'm thinking for my next grow I want to do a hydro system. I'm thinking DWC. I'm wondering how many watts I would need to grow 4-5 plants (all Indica). Also, if someone could explain what all I need for HID lights, like reflectors and such, (cuz I have no idea) that would be great.
this should be in general indoor growing........... you need something like this. ....... . http://www.hydrofanatics.com/600w-hpsmh-digital-fusion-grow-light-p-800.html you could get by with a 400w system and do your 4 - 5 plants but why not go big and get a 600w ...... i like the dual hps/mh just change the bulb flip the switch and your off.......
