Has anyone ever grown bare bulb vertical ? 360 degree of light.Then you've got to reflect it back and get more losses/heat etcbare bulb vert obviously captures it all well. I think the key is having the perfect coverage, intensity and distance from canopy to minimise all loses and maximise what a plant can take.
There's your first mistake. It only takes 24 of the single row 44" Samsung F-strips at 40 watts each (20% below test current) to hit 950 watts - Double row strips will do it with an even dozen. 25 piece price at Digikey is $522 for the single row - double row strips saves you $22. Add another $230 for the drivers. The .601 profile sinks from Heatsink USA can be added for another $88 for single row strips. The 1.00 profile for double row strips adds the same amount.
No, its called first law of thermodynamics - also known as the conservation of energy. HID may make more direct heat, but physics (the REAL physics) tells us that all that light being created *in an enclosed space* becomes heat as well. The only light that does not get converted to heat, is the light absorbed by the plant which is converted to carbohydrates (stored energy) - and that's a pitifully small percentage of the whole.
Seems like these lack a lot in the blue spectrum based on the spectrum chart.
Thanks, but the 44" strips limit modularity
22" strips are slightly more than 1/2 the price of the 44", so the cost difference is negligible.
Yes, it REALLY does - minus the SMALL fraction that drives photosynthesis and other plant processes. Try taking a physics course or two. In an enclosed environment, the electric energy of your lights is converted into two forms - direct heat, and electromagnetic radiation, most of which is in the visible light spectrum. When light falls on an object its either absorbed and immediately converted to heat, or its reflected/re-radiated. Light is not really able to be readily converted into other forms of energy other than heat. It can move electrons (photovoltaics), but there's not many solar cells in your enclosed grow environment is there? .
Yeah... that's just light heating stuff up....
And what objects bigger than electrons does light move?
Then why inject it into this thread? Maybe because you are AKA growlightresearch and nofuckstogive?
Yeah most people that can't handle their incorrect ideas being corrected tend to do that.
