a few thoughts and a bit of what i know , these lights are manufactured in china,by ctl lighting i-gro and several other us based resellers have them for sale ,i-gro looks to be the cheapest , to my knowledge icemud, toker69 and myself will be the first growers to complete a cannabis grow cycle with them here in the us i have searched high and low for videos & pics there are some out there but not a finished grow and review, i can say they have vegged quite satisfactory , i will start the flower cycle soon, the plants i finished with the 684 did not have a good start were to cold and the first 4-5 weeks were flowered under my budmasterI675xg
so i dont count those at all in judging these i-gro lights, you should be able to find a good amount of info on the intelligent gro site
i believe they use bridgelux diodes and heres the map of whats in them
i believe that includes the cob in the center
heres the estimated par
i have no real opinion on these lights yet but what i can say is i like them so far they run hotter than i expected
the controller is not a gimmick imho as it gives you total control over each spectrum channel and each hour of the day i can see where they could be used in many ways ,from getting a stretchy plant to tighten up its nodes by running more blue than red, or increasing reds to help a plant stretch thats to short, and even helping sick plants recover by giving softer light in a specific range of spectrum
its also nice to not have to buy timers, and you only need one light to do the job that it normally requires at least 2 lights to accomplish, and being able to dim the lights adds $ savings for times when you dont need them at full power, the controller is 70$ and optional it does not automatically come with a light , the big sell or no sale for me is quite simply how well they flower, i personally dont need a light that is an all in one since i run perpetual and have dedicated lights and veg/flower areas, but its nice to know i have the option,also you can control up to 10 lamps with 1 intelligent controller,
i am seeing some benefits to custom spectrum i had the lights a bit high and they started to stretch so i lowered the lights and altered the first 2 hours of the day to be heavy blue well the nodes immediately(2-3 days) got tighter and stems got thicker,
a thing i wanted to touch on , i have seen a bit of chatter around the forum on sponsorship and that perhaps we testers may be biased since we got "free" lights i cant speak for anyone else buy for me its like this, since i did not pay out of pocket it is not as important that these lights or any other item i receive be successful (tho i do risk all the meds from that run and the potential of all the supplies used are wasted and months of my time) not exactly free, so if these lights are great or suck wet dog fur! i want to report to you subscribers as honest and fairly as i know how, im not going to candy coat things, if they fail i have less motivation to want them to be great like i would if i saved $ for months and peeled off more than i paid for my last 2 vehicles combined!!
it allows me to be unbiased and honest about my findings , im not going to kiss butt on a sponsor nor would they want me to be if they are worth their salt and believe in their products, the sponsor model grow journal is a solid test ground and a good deal for
sponsors we all know word of mouth is the best advertising, i know i respect the words of my friends here more than some random websites claims,
just wanted to spit a few words on the subject so you all know how i feel and my philosophy on it
