HPS questions

I have one plant of low mids that is about an inch tall (already sprouted, only one "baby leaf" is still alive). It is currently on a 24/0 lighting cycle under a 20 watt aquarium fluorescent bulb. I want to change to a better, higher-powered bulb, such as high pressure sodium (HPS)
- What wattage and size HPS bulb will i be needing? what flowering cycle for vegetative stage? where can i get one of these in a big city?


I already have at my place a 60watt halogen and 100w halogen bulb that are not in use.
- Are either of these bulbs ok for growing a single plant of low quality mids? Which one and how high should it be hung above the plant and on what flowering cycle?


In 2 weeks, I will have about 10-15 baby shwag plants at the same growth stage that my mids plant is at now. At this point in time, my mids plant will have been moved to most likely a HPS or halogen light, and my baby plants will be several inches under the 20 watt aquarium fluorescent bulb. But, once they are ready to begin the true vegetative stage:
- what light source should they be moved under for optimum growth?

i read your other thread man and answered your questions there. i'm not sure a HPS would work for your situation. what kind of dimensions is this "locker" that you're growing in have?

btw, keep those halogens holstered, because you will just be wasting electricity trying to grow with those.

:peace:

toss the halogens out the window, they are horribly in efficent and put out the wrong spectrum for plant growth, for your single plant go with a 150 watt hps or there abouts, all you will grow with the halogen is a long stringy single leaf plant that cant stand up on its own
