LA Peyote Kush - Mars FC-4800 LED

Well, another crop is starting. Keeping it simpler this time with number of strains... only 3. LA Peyote Kush from Seedsman is one of those strains. Just received these from the GotM contest in October or November, getting old and i smoke a lot of pot... flip a coin, doesn't matter. Kinda excited to grow these for their advertised flavor as well as never having grown a Seedsman seed before. This is obviously a boring week, and that trend will continue for another month. However, the diary must start somewhere. I'mnot taking 20 pictures of a simply, tiny plant, so expect more of the same while it is boring. I'll be using a fully dimmable 150w light for seedlings and early vege. Some diy lights will be used as the plants outgrow that footprint. They wil likely spend at least 5-7 days under the FC-4800 before 12/12 light schedule flip. The FC-4800 is flowering 4 plants right now and doing a wonderful job as expected. A not on quality of lights -- most lights nowadays give you an excellent spectrum for growing. You can split hairs about CCT, but most of it works well. Where you get return on investment with a more expensive light is efficacy. You also get less heat with increased efficacy, but in some cases you may want that heat, so i leave that in a grey area. No matter what, we all save money if we spend fewer watts while producing same number of photons per second. You also get increase longevity with higher quality lights, like the FC-4800. Those advertised 50-60k hours of use are only accurate when run at a similar watts per diode as the FC-4800. At 0.25watts/diode, you are up against diminishing returns. More diodes don't help at this point. Watts per diode values higher than this will not reach the same 50-60k hours of use before dimming to 90% of original intensity. They will not achieve teh same efficacy. This is one way you can spot shady spec sheets. If yo do the math with the FC4800 and compare to Samsung's chip spectsheets etc etc.. it makes sense. When you look at cheaper lights advertising similar values, like 2.7-3.0umol/j range efficacy, you can see just how badly they are lying. This is also how you can see there is no difference according to samsungs own information between the H and B version of LM301. The "D" version is different. It is a lower version of the same chip... for a person (me too) who lacks the vocabulary to say it more eloquently and precisely why. Spec sheet don't lie! You can convert lum/w to umol/j. it just takes a conversion i know nothing about. Since we have a the spectrum maped out, it is possible though. these values are equal to each other when you do the math per bin... same tables, same graphs, simple changes of metrics used due to target markets invovled with the chips. Alrighty... 1 picture.. but made up for it writing a book for the opening week. ______________________________________________________ This diary is sponsored by Mars Hydro.
