Hi guys just a simple question for you re wattage - I have a light in my garage. On the bit which the bulb screws into it says 1500watts. There is no wattage written on the globe itself. I dont need or want 1500w worth of light. Q- Can i screw a 400 watt globe into this fitting without fear of shorting or any kind of crisis? Or is it best to buy a whole new fitting designed for 400w? Ta

Hey all, I've allways run my fans 24/7. One hydro shop has recomended I turn off my fans when the lights are off and start them half a hour after the lights come on so the plants can use the co2 that has been produced during darkness. Dose anybody else do this ?

The more you research something the more confusing it gets. Does anyone have info on these two brand names. For the same size the Mountain Air is $130 cheaper, is this a bad sign, or my good luck. Don't want to make a mistake because it is to replace the shit of a thing I already have but does not work. HELP!! PLEASE!! Aussie

Hey Oz Stoners Ive just germinated 4 seeds and have sowed them in cubes of R.W and have had them sitting about 5ml from a 40w fluro for the past 3 nights now [18hrs]. None have broken the surface yet. [cubes watered once when fisrt sowed] Considering it took a day to germ, there process hass just seemed to halt compared to growing in soil with sun. Are they establishing good roots, am i doing somthing wrong or is this normal? And just quickly does an overcast day produce better lumens than a 40w fluro? Thanks again newguy

Question. My friend told me today that if your doing a small indoor grow using compact fluros (as i am about to) that it is good for the plant to have a CF and a normal light bulb. Apparently they cover the spectrum better (CF's being blue, and normal bulbs red), as this would do them better thru veg and flowering. I have got 2 CF's (15W & 18W Energy Saving Warm Whites) and am wondering what would be better, the 2 CF's or 18W CF plus a normal 80W light bulb? I'm also pretty sure that the "Warm White" CF's are more in the red band, less in the blue, if anyone knows for sure, i'd appreciate an answer. Also, no replies telling me I'm a fool for growing with CF's …
