hi grapeedutchyy,kia ora all

good questions i'd also like the answers to. i'm new to grows myself, a little outdoor action but it's cold now, time to moves upstairs to my sweet loft space. read a lot of thread on the perfect led grow lamp. inspired to build my own despite my zero knowledge of electronics etc.(thermal footprint an issue in my home town-less fire risc as well) considered buying a growufo but think inferior to what you could build yourself and it's more fun.i'd like to be steered in the direction of diy led. plans photos and instructions to build. not knowledgable on leds?resistors?drivers?heatsinks?wiringetc.read a lot on the wavelengths(nm) and ratios required so i have an idea on the diodes but not a clue where to start on constructing the lamp.

respect to you all and can anyone help?
