do these lamps run on a standard high frequency electronic ballast? has anyone run them on a dimmable ballast turned down to the 400w setting? That would certainly be an inexpensive way to test them, just plug them into my current setup and move the lamps a little closer.

thanks for the info Coir and Dennis. The primary owner vetoed the idea of starting out with an 'unknown' lamp config. I guess I can't argue, seeing as how we are going to drop both of our savings into getting this business started and we need to reduce risks. I will be running an experiment...

I am mechanicaly inclined, I just can't spell ;-} It seems like all the fancy units (sunlight, bolder light, etc) use the same 315w bulb so I was a bit focused on that. If you have a part number for the 330w I would love to know it, or I'll just start searching PAR graphs. Another ?, do you...

Sure look like they're the ticket. Problem is getting the number I need to fit into my budget. Other companies want $500 each for the Phylips 315W setup. I'm hoping this would be less...

Hey GTO - You say you know the owners of the company that sells the ballasts. I am starting a Recreational grow op up here in WA and am looking for 72 of these lights. Can you connect me with somebody at the company or do I just need to call them up like any Joe Customer..? Not that I'm any...

Hey Preacher - sorry for the delay, was trimming my arse off and then went to Burning Man. The T5 bulb will do 20k to 24k hours. If you veg 18 hours a day for 30 days you'll get 37 cycles. If you replace the bulbs early due to lumen degration you'll get about... oh... 20 ;-} So I guess right...

I'd say that would be the use for them. I'm still getting my set up figured out and ended up vegging where I would normally clone. I've got to split my 16 pot hydro into two 8 pot setups so I can stagger the grow, then I'll have space ready for clones when they need it. In the mean time I...

Here's a thought. I looked at the cost difference between running the LED's vs. the T5HO's then compared that to the price difference between the two light fixtures. If I veg under these lights for 30 days, it will take 20 veg cycles to reach a return on the investment in the LED's vs. the...

I was going to correct you about the wattage 'cause the website says they are 22w each. Before I did so I went out and measured the fixture and with 4 lamps burning my meter says 78 watts, a little more than 18 but certainly less than 22. I wonder if my meter is bad... It's nothing fancy, a...

Growl - I would like to see a PAR chart and I only had to pay ~$50 each.

Yes Sir! I've been frantically trying to clear my room to move in this batch of clones, i.e. i've been trimming ;-} It's been about 19 days since I split the plants under the (2) 3500K and (2) 5000K T5HO's vs. the new Apache LED T8 tubes. Looks like the T5HO's are winning in at least the...

good point. I looked up a bit on Tobacco 'casue it's the only plant that comes to mind that we smoke other than cannabis. Could not find anything about flushing though they do seem to take weeks to cure it or use heat to cure it faster. Maybe that long cure helps process what's left in the...

I am new, but tend to lean toward flushing. I know with some things everyone does it "the"way because everyone has always done it that way. My thought on this is it's valid. I broke a small bud off a few days ago when pulling dead leaves. I set it aside until mostly dry and tried smoking it...

thx ;-} I changed the lights back to MH in the middle of week seven. Today marks the first day of week 9. Got a proper scope on Sunday and with that saw that I still have mostly clear trichs, some cloudy and a few amber... Nothing to confuse me or anything ;-}

I would love to hear any tips you have on fall conditions manipulations. All I'm doing at the moment is decreasing light time by about 15 min a night. Thanks ;-}

I will put 4 bulbs on one HPS for the entire next bloom cycle. I'm still trying to keep costs down prior to having distribution set up and profits coming in. To add another 800 watts for 720 hours, not to mention the bulbs and fixtures is another chunk of change. I know, I know; better bud...

Use to know a guy in high school, think his name was Caesey. His nickname was Caveman 'cause he never wore shoes and his feet were thicker skinned than rhino rumps. He was pretty savvy also ;-} I want to pull after flower production has stopped, and I want it well flushed by then. I would assume...

I personaly like the lighter more sativa high for recreation, when I hurt and it's late the heavier stone is better. Though I skip the couch and go strait to bed ;-} It seems the couch is where most people buying want to end up though so I'll be harvesting when I see some color. This is my...

Day 56 of Bloom - Starting to clear space for trimming and drying. I know someday I would have to clean up my shop... A few bud shots. Not a lot of difference from 3 days ago in a shot of the room. I have nutes down to about 440 ppm and I have cut lights back to about 11 hours now, 15...

Here is a picture of two similar buds - first is under the UVB Second is not under the UVB I think the UVB is producing a bit more trichromes, suppose testing will tell more. I have the light up to 45 min per hour for 8 hours a night. Will hopefully remember to change it to a solid 8 hours...
