Iโm not to sure about that ,tge blue and the red ..I was using a 600watt burple led ,blue&red spectrum and Iโm not sure if it was because I was maybe trying to do too many,I had 4 under it,I then added a phizon 1000 watt Led full spectrum and my plants ,well one of them started to fly and look great ,I sort of did a side by side ,2under the burple and 2under the full spectrum,the full spectrum blew the burple out of the water buddy ..Itโs my 1st grow,so Iโm know expert ..Iโll post a pic from about a week and a half ago and youโll see the difference,the blue and red spectrum are in the left ,the full spectrum on the right.Iโm not too positive,if could just be the wattage and my in experience,but now Iโve took the burple down and added another phizons (theyโre not the best but have Samsung diodes and look a whole lot similar to the spyder full spectrum,I know because they look ,it doesnโt make them the same)but check out my pic and youโll be able to decide for yourself..I hope that helps ,maybe someone more experienced can point you a bit better than myself ..hope you get on ok and happy growing..check the pic out ,youโll see what I mean )Iโve also put a pic up if the burpke on its own with a couple other ,I think youโll notice the bigger and better buds are the ones from under the full spectrum,tge little ones that werenโt coming on ,fingers crossed they will now I have the other full spectrum up are from the burple .happy growing and peace out
