Why how often do bulbs blow on hps and ur saying that two of your fixtures will support six plants for veg and flower note also I want a big yield and there will be autos in my veg I forgot about that lol one guy sed it would only run me 25 extra a month for a 400 watt hps and about 30 for a 600 watt I just want the biggest yeild possible the electric costs per month is not big deal that's why I'm thinking on hps also I need to read more about the heat above the light or do the come with the fan input thingy above
I replace my bulbs by run-time that I record on the box. I get a couple runs from each and $50+ for quality replacements. You can run them longer but they lose their intensity and that affects your yields.
Speaking of yields, Navy is right on about not thinking about your harvests before you get through a couple grows. No way to predict because of all the moving pieces. For a newb, getting your gardening skill down is the first step to long-term success.
I also run automatics in my grow, but only to get an early harvest. My diesel has a 4 week head start on my other plants that will be in veg for another couple weeks. Otherwise, I agree with Navy, autos tend to produce on the light side because of the short veg periods.
Six plants would prefer a minimum of a 400w HID and 3X3 grow space in 3 gal containers. Some growers use smaller containers for more plants, but I think 3 gal is a minimum for bigger crops. My cfl rig is for seedlings and small plants. You would need two complete rigs for one or two plants!
You can do way less lighting than what I'm suggesting, but your plants will look like little sticks with a couple leaves on top and pop corn buds. We see a lot of that around here and it's mostly due to inadequate lighting and novice gardening skills. You will get there Ehan, just have to put some time and money into it.
Here are six of my current grow under the 400w HID. They have been cropped at 2nd node, LST'ed and 63 days from dropping to soil.
