This is not approved by HLG in any way shape or form....lol
However, this is just the upgrade it needed. Thanks HLG, for leaving enough heat sink to add 3 more boards....i cant Imagine why everyone is not using these boards.....
@W J Rucier I did this run. I have a single plant under the R spec now but had a seed not pop. Hoping to clone it and follow up with 2 in there to see how that goes- also thinking of mounting B spec panel in a smaller dedicated seedling/early stage until up pot tent and keeping the R spec in the 2 X 3. (bought another driver) It's a 3' tent and I will dial the driver down to 60w.
yes they are b spec panels, hooked up to a seperate MEANWELL 320 so i can control seperately...
