jonny, I'm sure I'll catch shit for this, but why would you replace it every cycle? THAT is where you will be wasting the money, imo. Invest in a good bulb (I use the eye hortilux) and use it for a year. I run 3 1000 watt bulbs in flowering, and I replace them every 12 months. There is no noticeable difference in yield and potency from the first rotation under the bulb, to the last.cool beans joc...good to hear b/c I'm debating between the htg bulb and a hortilux bulb. htg is half the price so I'm leaning toward that. like you said, if ya just replace it every cycle, it should be solid.
A minor beef, but you reversed red and blue. cnhttp://www.youtube.com/watch?v=cgb_Khtqa1Q
The winner in this broad test was the Hortilux super

Just a quick observation, the two important light zones for plant photosynthesis are the areas from 400 to 530 nm (red), and from 620 to 720 nm (blue). The yellow in the middle throws off the readings, which can increase the lamps PAR score, but does not necessarily look at those two important red and blue bands.
If you compare the output of just those two spectrums and factored out the unnecessary yellow, the Ushio wins, even compared to the Hortilux
This was a quick look and there's bound to be more data out there.
I fully hear ya on the fact that less $$ will be spent over a period of time for a hortilux b/c you can run it through 2 cycles but right now jonny is poor after dropping $1k on his grow tent setup and cheap / effective is what the doctor ordered.jonny, I'm sure I'll catch shit for this, but why would you replace it every cycle?

Just my opinion, but I think you'd be way better off buying a top end bulb and using it for a while as opposed to going cheap and having to replace it often.
Sometimes...I have issuesDoes Jonny always talk about himself in the 3rd person .

It is the high frequencies of the digis verses 60hz mag....it vibrates them apartI personally use Hortilux with magnetic ballasts. I ran digital for a short period and the bulbs degraded much quicker. I believe this has something to do with the hot start of digital and maybe Ushio addresses this issue?
View attachment 2439604CMH has a lot of critics. I haven't looked into it, as I'm headed for 1000w hoods, but the criticism centers around the added light being in the yellow spectrum, and not useful for the plant. Anyone have a spectral output for CMH?
Understood. Ya gotta do what fits within the budget.I fully hear ya on the fact that less $$ will be spent over a period of time for a hortilux b/c you can run it through 2 cycles but right now jonny is poor after dropping $1k on his grow tent setup and cheap / effective is what the doctor ordered.
I'm looking @ $50-60 for a basic hps or $90-100 on a hortilux. Personally, I've been browsing these forums for 5 years now and I've seen seasoned growers flower dank with a 150w hps security light from home depot so no one will ever convince jonny that a $100 bulb is required to grow chronic.
Jonny however is a critical thinker and if in the long run the hortilux pays off, I will be using it my next grow. But for the purposes of this grow, jonny needs cheap and effective as the piggy bank is tapped out so the cheap hps bulb will have to do. When I get to my chop time and clock out on the final dry yield, that shall be the all telling evidence that points jonny in the right direction.
and for your 1000 watt here you go http://www.ecat.lighting.philips.com/l/lamps/high-intensity-discharge-lamps/ceramic-metal-halide/energy-advantage-cdm-lamps-with-allstart-technology/928601172801_na/CMH has a lot of critics.
