Hello folks! I'm new to the grow scene and have started my first grow from seeds. My setup consists of two White Widow Auto plants using DWC bubble buckets with rockwool starter cubes and hydroton in 6 inch net pots in a 2'x4'x7' Gorilla tent and Advanced Platinum P600 LED light with a Hydrofarms LGBQM QuantumPAR meter. I'm trying to determine if I should just set the lighting distance from the top of the week old seedlings based up measured distance base on manufacturer specs or actual micromoles per square meter readings? It seems that actual PAR measurements with a Quantum meter would trump any physical distance placement of the lamp from the plants. My 5 day old seedlings are currently getting about 325 umoles at their leaves using the VEG only setting on the light. I don't want to burn the little ladies by moving the light too close but I'm not sure of what the optimal umoles/m2 level should be for the different stages of growth: seedlings, veg or flowering. Any advice on how many umoles I should shoot for at each growth stage? I've set up the tent on a 18/6 light cycle.
