Hiya So i got me a pretty cool lamp which allows different spectrums to be selected. Number of diodes White (3500k):424, R(660nm):112, UV: 8 IR: 8 Suggested setting for ripening is R (255) G (0) B (255) which gives White (3500k) 60, R(660nm):112, UV: 8 IR: 8 all on. Is this the best of the...

60x60cm tent basic 120w QB288 DWC autoflowers so 12 + weeks, averaging about 160g per grow.

Cheers BIlly

Hiya, I got a new 200W full spectrum 4 bar lamp and im not sure its working correctly. I know they arent super accurate, but my android PAR meter gives a reading of 980umols at about 25cm. Does that sound about right? When i first set her up im fairly sure i couldnt look directly at the light...

New light day woohoo :bigjoint: Ordered 18.05 arrived 07.06, pretty good. Measures 220w from the wall. This thing is COOL. Everything worked great, downloading the app which allows you control the leds. All on (low power) RD (just the 660 diodes) WW (warm white diodes) UI (UV + IR +...

Ok thanks thats a significant reduction in RH cheers!

So lets say my RH was 60%, how good a job does the AC do, does it make a big difference? Thanks!

Ok thanks for replies. I might run a GH 3 part dwc next to my usual Canna and see if i can see a difference....

Cheers, you do DWC?

Hiya Ive been using Canna (actually both Hydro and Aqua) veg and bloom but to be honest my last few grows have gone tits up (over/underfeeding, lockout) and im thinking of switching to General Hydrophonics veg bloom and micro. Im sure the issues i had were my fault, im sure canna is fine but...

Cheers. But an ac unit has warm air coming out the back which needs ducting to remove it correct?

OK thanks. The dehumidifier I have lowers RH but raises temps so I should replace this with an ac unit to kill two birds one stone. Cheers!

Hiya Im gonna run my tent through the summer. It can get pretty hot here, 95°F+ isnt unusual so i plan on buying an AC unit and im wondering what effect this has on humidity. Quick google say yes AC units will lower RH which is good. Can anyone confirm this? Thanks!!

Yeah thinking about investing in a par meter do you have one?

Hi, As per title, I've used my basic QB288 for about 7/8 grows now. I know they say the last for 500000000 hours or something but I'm just wondering if it's time for a new one? Cheers!

Ok thanks for the thoughts guys. Just ordered my first bar set up, going the Alibaba route cos im broke...to be honest i have a cheap chinese QB board with a mix of 3/500k diodes plus some 660s and a few UV/IR diodes and i havent been blown away by that so im taking a bit of a punt on this one...

Thanks bars 1 boards 0!

Hi Is one better than the other? Diodes are diodes right, if you have some 301bs and some 660s, 730s etc in whatever configuration it shouldn't really matter right? Everything seems to be bars in favour of boards, I just wondered if there's any reason they perform better? Thanks!

Hmm not quite the same spec: 301b 3/5000k mix x 424 660 red x 112 UV395 x 4 IR730 x 4 You can control the spectrum with remote control. I am FAR from an LED expert but this looks pretty nifty to me;

Thoughts? 240w 301bs +uv+ir, which can be turned on separately, been told 100 + 50 shipping...looks legit to me https://www.alibaba.com/product-detail/Lm-Smart-Bar-Mesh-Networking-Remote_1600287310623.html
