Hi, I'm new to this group but have been growing for too many years to admit to! I've used both HID's and HPS's with much glee and success. I've seen reference to these compact fluro's here and there and also I've seen photo's of very healthy plants that were vege'd with a CFL or three. As they seem ideal in many ways for indoor I would have thought that they would have been looked upon as a real revolution in growing under lights. From what I can gather from this forum, the general opinion is that while these lights might be Ok during the vegetative stage, they somehow fall down as far as being an effective source of light during the flowering stage....

I was thinking about getting a small grow tent off of ebay and putting a 400W hps in it. Would a fan like this one work in it? http://cgi.ebay.com.au/120mm-exhaust-fan-h...1QQcmdZViewItem

Been looking at some Cool Tubes and threads regarding them, some peeps say that you can get cheap or non-genuine ones. How can you tell them from the real deal? Jimbo

hey hard rubbish was the other day and i got a complete 1000w setup, ballast globe and shade. It seems to be one of thoes industrial type shop lights, and im just wondering wether its HPS or HID. I tryed to plug it in but the bulb must be shot. I was thinking if the ballast was broken then it would probably trip the safety switch yeh ? well it didnt, but the globe didnt turn on so im guessing im up for a new bulb. Anyone got any ideas on how to tell a HPS ballast from a HID ballast ? cheers also, what size room would a 1000w fit into ?>

I was wondering what the light spread is like from the Cool Tubes that come with the small reflector? Is it adequate? Does it spread the light as well as batwings for a 1000w bulb? Can you place a batwing over the top of CT's? Jimbo

My 400w eye hortilux is making a noise, like a humming with a mix of some kind of metal. Its not a super loud noise, but i was wondering is this normal? I've been running this light bulb for about 3 months so its not old, and not brand new. Did i just never notice this before? Or is the bulb dying? Will it blow? Keep in mind, its not my ballast, my ballast has a hum but is far away. Thanks guys.

howdy was wondering in the situation where one knew that their electricity will be cut off for an hour or so between 8 am and 12pm and they are mid to late in their flowering cycle, if that the power cut should be ignored . ie. leave schedule with the break in it, or change schedule slightly . ie. longer dark. any ideas? would be nice to know what to do in such a situation before it happens!
