I love how much I am having to repeat myself,I said it produces a full growing spectrum,like the optimal for plants,this unit is designed in the uk and made in the uk,not in china,as I said the only "green" are 3 diodes and they are turquoise which is actually more blue than green,so its doing several blues,and several reds(including uv),and orange and that is it I think.I am not saying red and blue doesnt work,my avatar was grown with a 125 clf that was dual spectrum,I am just saying that it is well documented that plants do need other colors than blue and red and yeah I know green isnt one of them,I have been growing a while,and also have more access to books etc than most people due to my job,. I hope this time people understand I mean a "full growing spectrum" like optimal light, I think my plant speaks for itself,its under the 90w LED and is only 29 days into flowering
