Sounds like what I already said... a the Spydr 600 can replace an HPS1000w depending on which one. I said that above. How many people do you know that are diy growers using 1000w 'high end' HPS in a 4x4 tent? Seeing as how you care comparing electrical watt for watt, I can see why you are confused. Why don't you tell us what you consider to be a high end HPS fixture, and I'll compare the PAR readings for you.
I agree with you about the marketing BS, but that's in every business facet/model.............we give out degrees for it
65 degree SECONDARY lens angle to get those #s @ the cost of coverage area and possible pigment degradation from intensity== bleached buds, NO it's not a good thing imo..
NO NO NO, a spyder 600 CANNOT replace a 1000 watt HPS, you would need at least two of them to replace a 1000 watt HPS.
the V2 model is 450/660nm, mostly 660nm ........the spec looks familiar
, using the same osram oslon chips as the zelion to hit those umol/j #??not sure, diodes look bigger, could be the lens though
Do you have a link? I am unable to find tests related to many of the LED grow lights allegedly completed by Sunlight Supply. In most situations a 1000w HPS in a greenhouse environment is not air cooled and it will be mounted 36"+ from the canopy. This is why they claim the 600w will match 1000w in some greenhouse applications. If you move the bars to touch eachother at the center, you get max PAR readings. These readings do exceed those put out by a DIY air cooled 1000w HPS.
The test data isn't published. Just from conversations with my rep.
those are silly marketing faux claims. If one moves all the bars into the center, then the foot print doesn't cover the same square footage. Similar to a high bay light with light focused into the center with severe dropoff around the edges.
uhhh, ok, I'll take your word on it. lol
it won't replace a decent quality 1000k hps either. but considering the price of a BML 600, its quite reasonable to compare to a high end HID.
It's intended to replace a 600 hps. The spyder 1000 will replace a 1000hps
Search bml spyder on YouTube. They test 600 and 1200 in a sphere.
I have been a certified greenhouse manager and worked in commercial ag for some years. To clarify, marijuana is unique in its photo cycle. Most crops do NOT behave in this way and flower or fruit on a timeline based on a number of variables, time of year, temp, time since germinated, climate variables etc etc... So in a greenhouse application the use of artificial lighting is often used to lengthen a photo cycle to mimic a different time of year (not to induce flower, just to promote spring/summer growth) rather then actually use the lighting for its photons. You are still more Dependant on the sun even in winter to grow your crop. Usually the lights are MUCH higher in a greenhouse to cover the max footprint possible and really aren't giving the plants much. This is part of the reason you won't see LED's growing tomato's or cucs commercially anytime soon. Plus in a greenhouse the dreaded heat from the HID is a big plus in winter, depending on where you live. So personally I find the commercial greenhouse argument erroneous.
I get your point, and this would be a good rule for everyone commenting here I guess. If you don't own it, don't argue against the merits of it. I do remember you said you weren't impressed with BML. You were also saying that a Spydr 1200 under a 4x4 scrog was a waste and no one would use that in a commercial environment until I showed you the pictures of a medical cannabis grower doing exactly that in a commercial environment. You didn't own the light, but you had a lot to add. Just be mindful of that when you're giving advice on light etiquette. Interestingly, Stephen said that Sunlight Supply has tested every light out there, but they don't publish the data and he heard it from a rep. I'd say that's not very legitimate when applied to your rule.
Thanks. When you say 'best yields under the Spydr alone', did you use the Spydr from seed to harvest, or did you use the Spydr for flowering only? I have heard some don't use the first gen throughout the grow cycle because of stretch. Do you have any links to your grows?
