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

Yeah it could be. You really need a pH and EC meter. Spend as much as you can. Critical bit of kit. But those lower single leafs always go yellow and drop off, rest of the plant doesnt look too bad.

PH unknown - dude that's not going to do you any favours. Even the cheap ebay yellow $5 pH pens are better than nothing.

Well, she is still alive but not looking great. I'll get something to smoke but not expecting amazing quality. The constantly rising ppm tells me shes not feeding, even now she is down at 340~ (tap water 180) so shes hardly getting anything, but still it goes up. Ph has been easier to control i...

Thanks. Ummmm to be honest, ive never really paid any attention to that. I use whatever scale my Milwaukee pen has as its default. If i measure my rez as 600 one day and 500 the next then i assume my ppm has dropped. And vice versa. As long as im not taking different readings with different pens...
