alighieri Reviewed by alighieri on . Ebb & Flow Noob Needs Help, Please. Hi all: medium-time grower (organic soil & DWC) trying hand at 4x4 ebb & flow table. My clones (GHS White Rhino, sativa pheno) looked good when they went in a few weeks ago, but under too little light. Have since increased lumens but clones seem to be struggling and nowhere nearly as healthy as their organic soil neighbors (TGA's JTR). The WRs are between six and nine inches tall (I'd like them to be 15-ish before flowering). Am using cooltube 600 watt HPS and a Procyon 100 - equivalent to 400w Rating: 5
