    water resistant solder mask and also resistant to acidic environments

    That HlG 550 is just essentially 2 kits on a large heatsink with a 480w rated driver the hlg 480h c2100a driver,


    although we don't offer 1 large heat sink 2 x ISH265 pro kits with 2 heat sinks instead of 1 run off the same driver HLG 480h C2100a would be $893.34 Canadian dollars plus shipping which would be about $80 Canadian dollars for that weight. so total of $973.34

    quality wise we use the same manufacturer as HLG do and on top of that due to our pcb design and circuits we actually have a higher umols/j rating than HLG by a touch.

    I hope that helps

    HLG have been in operation for 3 years plus, we have been retailing since April, our market is not hlgs market, we are not scaled for commercial fit outs as yet and have never claimed to be. We have countless growers on Instagram and other forums using our lights, being based in the UK has its challenges for this type of industry, the UK doesn't have commercial scale grows that you are requesting proof of. We live in a totally different country with different laws governing us, on top of this we have our customers privacy to protect. We are not in a position to break this because you want proof of a grow. sorry

    We can retail our lights but we have to stick to certain guidelines in how we operate. This is why we have donated kits to the forum for testing.

    There's not much more I can offer you really so if following along forum journals or the sphere test results published on our site arnt any good then maybe you should consider HLG and pay the extra $370 for the light. We would like to help more but we cant. Again sorryif that's a disappointment for you.

    Hi mate.

    Are the 2 sick plants next to each other?

    Are they to one side or end of your groom?

    Have you checked temps in different places around the tent?

    I'm thinking they may be in a cold spot in the groom?

    yeah they are next to each other,the thing I didn’t say is that they all got really dry the other day ( just couldnt get in the room)they seemed to be all drooping for a few days,but the 2 in question have not recovered for some reason,when I google the symptoms s it looks like over watering,strange!
