O.K where do I start, I think the present equipment supply industry
Is allowing many growers to travel unmapped roads. First of all ask yourself, Why did this store owner open a store? Because he wanted to help me become a great indoor grower? No! He wanted to stop being screwed for the outrageous cost of equipment! and did so by buying enough that he can now pass that screwing onto you. See the chances are very great that you are not your local indoor equipment suppliers customer as much as you are his competition! So ask yourself why would he want you to become successful as a gardener? Would it not serve his interest better
To sell you every product under the sun and then upon seeing your frustration advise you its not for everyone! How many people get into it with big hopes and dreams and spend allot of money chasing the next best Lamp or Ballast or Nutrient or Plant Stimulate or technique only to give it up before ever getting that over the top crop? 9.5 out of 10? The store owner makes no money if you dial right into a simple consistant application format.Who do think ownes and publishes the magazines with all the technique articles and applied gear articles and new product advertisings. Allow me to pull that trebbile hook if you wish! The most important part of the indoor lighting application is the “CRI” (Color Rendering Index) and the “Kelvic Range” (Color Temperature) all the lumens/watts in the world mean nothing without these! A classic example is the LOW PRESSURE SODIUM LAMP 180 watts consumes 182 watts producing 32,400 lumens that’s 180 lumens per watt currently the most efficient lamp available but they have a CRI of 0 to 20 and Kelvic Temp of 1600 to 1800 straight yellow light! making them worthless in the garden!!!! Otherwise there the most efficient lumen to watt your dollar could buy per KWH
Plants have specific light spectrum needs at different points in there lifecycles. Knowing what these are greatly increase the talents of the gardener! Anyone who tells you this is not that important is telling you the suns color in May and the suns color in November has no major effect on the plants lifecycle or its productivity level.Common sense should tell us there is something here worth studying! The charts are nice but they fail to address the actual electrical consumption of the applicable fixtures there by making the lumens per watt category incorrect and further rendering the charts figures invalid . A 400 watt MH consumes 425 to 462 watts depending on Lamp, A 400 Watt HPS S51 consumes 457 to 490 watts depending on lamp , A 600 Watt HPS S106 consumes 665 to 685 watts depending on lamp , A 1000 Watt MH M47 consumes 1070 to 1080 watts depending on lamp, A 1500 Watt MH M 48 consumes 1605 to 1615 watts DOL, A 1000 Watt HPS S52 consumes 1100 watts DOL. These are actual consumption figures as posted by the ballast and lamp manufactures which people might like to use in there postings as a point of reference there by helping to make there contribution technically factual. The distance one can maintain between plant and lamp is dependant only upon ones ability to maintain a temperature that is conducive to plant growth without burning your specimens, if you can keep a lamp cool enough to place it 18inches off you plants then there you go! 18”. Oh and let me add that successful healthy bumper crops are not created by lamps alone it is the combination of many factors, light intensity and spectrum, nutrient,Co2, Humidity, day and night temperature, timing, technique and so on! It is though deserving of compliment that you possess a passion for what you do and strongly desire to master your interest and contribute your findings to a larger collective. After 20 years I can humbly say with every passing day I reaffirm how little I know and how much there is to learn.
