Back at ya Chaz That was a blast from the past. All 70's Any chance you're related to the great Tommy Bolin?

Hey Splifferous great post. Keep us updated with how this grows for you. One of the areas you touched upon was using a germicidal UV-C spectrum which I think would be last spectrum the wide spectrum grow lamp should emit. So I would guess if they're going to get into sterilisation using...

Glad to see someone with a wider understanding of plant electrobiology take this up. I've not seen much on this topic and I'm curious as to why not. Much is known about the lights on - lights off relation between plants and light source but I've not found a lot of research on narrow band far...

Quantum meters are calibrated for sunlight and show energy levels in photosynthetic density or PPFD that fall within the 400-700nm wavelengths. Perfect for measuring plant light levels. That looks like a specmeters.com meter in the video. I use an Apogee MQ100. Not any real difference and...

Does anyone on this thread have any experience with using LEDs that generate light in low wattage, less then 20 watts per LED array, @ 725 nm that would run for maybe 10 minutes after lights out to induce a reduction in normal phytochrome switching from the plants usual 2 hours to like 15...

Just wondering if you ever got the 420's and how did they compare to the 400's for you? Clones seem to be rooting nicely in a week under this 100 watter @ 500 umoles. Not a bad side light either from the looks of it. http://www.youtube.com/watch?v=7Vh_8sdpNiQ&feature=channel

I found this article of interest since the LED lamps I have tried that emitted blue or red or a combination of these visible spectrums were missing the blue/green spectrums that plants require for the coratenoid regions which are partially outside Chlorophyll B in the UV region but act as an...

Reading through this thread I don't see where a journal was ever posted up. Did Bubble ever complete a full grow under these lamps? I have read on the web where the wide spectrums PAR blends that emit wavelengths in the UV, Coratenoid, Red/IR/FR regions does create greater trichome production...

Compared to other lamps you've used and even the 400 inda-gro how's the daily rate of growth going on the 420? It sounds like it surprised you with getting onto the lamp itself?

yeah! what he said

Hey Albsure I used to have a suit just like that! Cmon man. Give the guy a break. Don't you think it's possible that the technology can work it's just a clumsy presentation? I mean the owner of this company must be selling these to other growers who just don't wish to share their...

Glad to see you're back! Are you running the HID and HFIND lamps completely separate so we can tell which source does what? It looks like in some of these pictures there is a MH next to your new hood.

Not much more to see here I guess. At the start I thought they'd be all over this grow. Been looking around and I found this video on a side by side comparing 1000w HPS to 300 watt induction but not much out there. checked out the site and recommending a low wattage LED bud booster which is...

Mike I went to your site @ http://www.progrowlights.com/Products/tabid/813/ProductID/21/Default.aspx to look at possibly buying the 400 watt HFIND for a test grow. I try to keep an open mind and watch the forums but there are things here that beg answers from the top; Why not sell the...

I ordered two of the lightrail 5 systems yesterday so I'll have two 8 ft rails to work with. Can't wait. I was thinking of trying one with my normal 400 watt metal halide hood and the other with an induction lamp that I'd build myself to save $ and make it lighter. I like 'dirt cheap' so I...

I was thinking of going from my magnetic to digital ballasts for 4 of my 1000watt HPS lamps. Do digital ballasts need any kind of surge suppression on the incoming power? I guess I'm asking if they're more or less susceptible to incoming voltage fluctuations?

My friend had a 1000 watt metal halide lamp with like 10,000 hrs on it, blow up. Is that another reason you're supposed to relamp more often on the metal halide lamps. Or do you think he may have had some kind of voltage surge that caused this? It was a mess.

Luxim is Plasma right not induction? I took a look at the Gavita 300 on this link and it looks like it cover the entire spectrum nicely but the chart on their site is hard to read. So would this be a way to take my grow all the way through with just a single light? If you're using one and...

If you run any lights on a light rail don't the centers get twice the light as the edges or ends of the rail? Do you have to adjust for that?

I'm interested in trying the Blackstar 240's for flowering on a light movers. I would be covering a 20' long by 10' wide area. Has anyone here tried these on lightmovers or are they better stationary?
