    Latest UVA vs UVB cannabinoid test results

    Possibly with regards to the production of cannabinoids but certainly not with regards to the degredation of already produced cannabinoids as one is a biological process and the other a chemical process. Do you have any evidence to back this claim up or is this just a hypothesis? I'm using a...

    Latest UVA vs UVB cannabinoid test results

    Hey guys, loving the experiments and the data they're producing! How come the tests are being done with the Arcadia 6% UVB Bulb? Surely something designed for horticulture with a better spectrum including more UVB would be more appropriate? I've had what I think is some pretty good success with...

    Bluelab ph controller

    check out ledgardener's "automating your grow with home assistant" youtube series. He basically uses a rasberry pi, ph meter and periscopic pumps to create a ph controller. Will probs work out cheaper and allows for you to automate other aspects in the future using that platform :)

    Water chiller for a single GHE Waterfarm

    Don't worry, you made a good investment into that water cooler. I've got the same one and its over 12 years old, second hand and still works perfectly! I paired it with an Eheim Universal Pump (the smallest one, think its about 300L/min) and just leave it running 24/7 to cool my res of about...

    DWC - Brown spots on leaves and roots??

    I've had leave look exactly like that at the begining in a couple of my last grows. Was eventually solved by adding bennies, cal-mag and removing everything else apart from A + B. I've been running bennies the last few grows (Greatwhite and Mammoth P) and I will be always from now on. There...

    I was planning to give this a shot with all of my AVB and trim. With this method will I have to worry about a little budrot being amongst the trim if i just let it dry in a bucket?

    Urgent help please - a bit of mold on one of my Colas

    Thanks so much mate. I think I may have got the rot really early and its only affected the one bud. So im going to chop it all now and dry it with lots of air flow! I'm only harvesting a day or two earlier than what I planned so no big deal. Should i chuck the whole of the rotted Cola or just...

    Hey guys, I think one of my Colas is molding a bit and I need to know what to do :( The plant has been flushing for 3 days in DWC so i could chop it all now and begin drying. Here are pictures: So far I haven't seen any other mold. I've chopped the affected Cola and chucked the moldy...

    Bag seed from 30%thc cultivar

    Hey guys, Got a bit lucky and scored what looks to be a viable seed in one of my prescriptions. Its from some pretty awesome stuff so I would love to pop it and give it a shot :D However, over the years I've heard its a bad idea to pop bag seeds from sinsemilla as its likely they will hermy...

    Best position and timing for UV lamp in my tent?

    The far red thread

    Hey mate thanks for your help but I've set the driver to output about 1 amp. It's a HLG-40H-30A which is adjustable between 0.8 ~ 1.34A. I could wind it all the way down to .8A but I don't have anything to run the lights at 350mA. However, looking at the data sheet more thoroughly I've found...

    The far red thread

    Hey mate, thanks for your input! I'm unsure as to the wattage which the PPF value is using. From https://www.cree.com/led-components/media/documents/XLampXPE2.pdf - it tells me temperature (Tj) is at 25 and the "calculated minimum flux" is 2.1 umol/s" - this says its "for reference only". I'll...

    Supplemental LED Lights (660nm, 730nm etc) for old QB288 v1

    Thanks mate, much appreciated! I ended up going with the A types like u recommended. I like to keep my drivers outside of the tent to keep heat down, I just run longer wires from the driver to the LEDs. I went with the HLG-60H-48A instead of the 54 as the 660nm XPE-3 have a max amp of 1.5 (the...
