Anyone switch from 1000 watt hps to LED yet?

I'm not there yet but I'm getting closer. Moody - when you are you going to kick off your grow .

Peace.[/QUOTE]

Hey bigsby....I have my beautiful new LED light that is hopefully getting hung tonight. My closet has been covered in mylar....I'm picking out new clones tonight and waiting for a few special ones from a friend! :thumbsup:

I'm going to be doing an all coco grow, all house and garden nutrients, all LED....I'm super excited. I should start the thread for it within the next few days! :jointsmile:

if you want to learn more then be humble....people here will bend over backwards to anyone asking for help in a civilized manner!

peace!:hippy:[/QUOTE]

exactly....remember, we all are here to learn and SHARE information. You don't have to agree with everyone or even understand their methods....but just because you didn't like something or haven't heard of it working doesn't mean shit! Everyone has a different technique and some people are much more willing to step outside the box....be humble, be kind, listen and learn! :jointsmile:

I'll be looking for the grow log. Post a pointer here or as an album so I can fine it.

I think I may be over the fence on this decision. It just makes so much sense for my situation. Damn I wish I didn't have these time constraints. I've been reading / learning for weeks. I'm ready to do some application. Nah. I still have a ways to go before I'll be ready.

Oh, and remind me not to cross you guys. Give cliffcliff some space to breath. He buttered himself up with honey and passed out on an anthill... let him open his eyes to look around. He's picking up knowledge here. Otherwise he wouldn't come back for more.

we want him back as i think he got it....my last post was meant as peace offering in listening and taking notes....no matter how smart you think you are there is always room for improvement in all of us in gaining knowledge and learning from each other because we all share the same goal...to grow the best we can and get the most out of what we have! so cliffcliff come on in and join us....no one is going to bite your head off or piss in your wheaties....just ask us how we got to where we are and not telling us with your first post what we cant do or accuse us of manipulating facts...thats all....and thanks for your contributions bigsby:thumbsup:

Boy those are gonna be some swollen eyes when they do open from all the ant bites!

After I realized that my initial post in this thread was condescending beyond even my typical level, i calmed down and just decided to rebuke with fact and no other thing.

Ok, so as you can all tell Iâ??m one of the new kids on the block. I will do my best to be as precise and informative as possible while not trying to step on anyoneâ??s toes. Banter back and forth is good but fighting and taking jabs at one another doesnâ??t do anyone any good. Ok, so enough of the peace and love shit, here is my opinion on Perpetr8râ??s question.
First, my hat is off to Stra8outta. Guyâ??s like this who take chances with new equipment and products are the reason for the awesome advances that have and will continue to take place in this industry.
There are a couple of problems with this discussion that should be addressed so that Perpetr8r can step back and come to his own conclusion on what he is trying to accomplish in his grow. First, in my opinion grams per watt is really only half the story in trying to compare LEDâ??s to HIDâ??s (HPS/MH). See at this point while LEDâ??s definitely have the spectral advantage energy wise they are lacking in the intensity department (getting much better though). Here are two examples to help prove my point. First of all I have a meter that measures Photosynthetic Photon Flux (PPF) which is measured by micromoles of photons per square meter second. This meter fairly accurately approximates the radiation between 400 and 700 nanometers which are the most important wavelengths for plant growth. Itâ??s not quite a spectroradiometer but for this discussion it is plenty accurate, at least to make my point. Regardless of the size of the diodes and how many are grouped together the readings as you get further from the light rapidly drop off as compared with HID lighting systems (readings fall drastically every inch from the light). In addition, the cone of light coming of the LEDâ??s is almost non-existent. Meaning within a couple of inches of any side of the light fixture the readings are very bad in terms of adequate light for plant growth. Second, the evidence of this phenomenon is present if you read into this thread and the one that Khyberkitsune directs us to called Pinstripes 2nd try. Stra8outtaâ??s .7 grams per watt using LEDâ??s similar to traditional HIDâ??s (what about 1 -2 feet above the canopy stra8outta?) is a real testament to his horticultural skills. Great job man! Unfortunately it proves my point when you compare it to pinstripes 22 watts, 38 grams in 14 weeks (14 weeks? Not good on a 7-9 week variety) at 1.72 grams per watt with what sounds like by his own admission zero horticultural skills. In Pinstripes scenario the LEDâ??s are being used at their optimal distance from the plant and the plants are being kept mad small therefore he has tremendous success. In Stra8outtaâ??s case he is trying to cover many more plants that are much larger and therefore he has a tremendous light loss as the light travels down through the canopy (my bet is less than 20 micromoles of light reaching the bottom limbs of the plants). This loss is going to bring overall yields down as compared with HIDâ??s. These lights as described by the manufacture can be used up to 13 ft away from plants in a commercial greenhouse setting. I can assure you that hanging the lights this high in a commercial setting could be used for one thing and one thing only, photoperiod interruption, which is also done with 60 watt incandescent bulbs in commercial greenhouses. Only a minimal amount of light is necessary to trick the plants.
Ok, so there is some proof to my statement, but I still have not explained why g/w is only half the story. Assuming Perp that you are a RI patient or caregiver and you understand that you are legally allowed to have 12 plants in flower, using Pinstripes method you would yield a whopping 152 grams off of your 12 plants. Yea, I guess you would have only used 88 watts of power but you would have only legally have produced 5 and half ounces in 8-14 weeks. Ok, so now letâ??s look at Stra8outtaâ??s .7 g/w. Yea, this as I have said is really good, especially for LEDâ??s, but what could you or have you produced using the same setup (# of plants, nutrients, etc.) properly outfitted with HIDâ??s and cooling. My bet is at least 1 g/w if not more. That is a difference of 300 grams per 1000 watts. This is almost 11 ounces of herb. Since electric bills are paid in cash money and that is all we are essentially looking to save on unless of course it is all about being â??greenâ?� and lowering your carbon footprint, well then LEDâ??s really donâ??t make economic sense yet. The $200 and lets say for argument sake being somewhat outrageous $300 extra that the HIDâ??s and air cooling are costing to run over the LEDâ??s could be covered by 1 of those eleven ounces or getting crazy RI style 3 of those ounces a $100 a piece. This means you are still 8 ounces or a half pound richer by using HIDâ??s over LEDâ??s.
So Perp its up to you and what your goals are. Shit, if you donâ??t give a fuck about plant limits, LEDâ??s Pinstrip style may work for you. If the # of plants and so does the electric consumption because you not ligit than Stra8outtaâ??s style setup might be best. All I can say is you have to ask yourself, what is my situation?

Thanks to everyone that contributed to this conversation I had made my decision to wait on or about the fourth post but this thread took on a life of its own... so I watched it
Futureboy, your line of thinking is the same as mine. I do plan on staying a caregiver and do stay within my numbers. It is my determination that I would not be able to maintain my current level of production without an exorbitant amount of LED lighting to replace my current 1000 watt set ups. Though from reading I do believe that if you are doing a SCROG , then LED would be your top pick. No need for the light to penetrate the canopy in a scrog. Thanks again to all!!
Peace :stoned:

[futureboy]

Right on!! Good decision, and great question that hopefully in the near future will be a no brainer for LED's. Being 'Green' all around is good in my book.imp:
