    More THC testing – UVA vs UVB vs near-UV

    to be honest, the reptisun 10 was similar spectrum but I thought I’d the Migro’s designed for plants it’s a safer option. I’ll attach the reptisun 10 for information, it’s actually quite good for plant uv, worth trying out as it’s got a lot bump at 310nm and 365nm then what looks like 405nm and...

    More THC testing – UVA vs UVB vs near-UV

    Just for information, here’s the uvb bulb spectrum I used in the last grow. It’s actually a T8 although I think I said T5 earlier? I confused it with the reptisun 10.0 T5 that I almost brought, although that spectrum looks good too.

    More THC testing – UVA vs UVB vs near-UV

    I might look into it, although if I haven’t anything from the last grow and my mates out I’ll have to do it again and the cooler weather means the CMH is on and won’t be as controlled? I would love to see some results myself so a possibility of splitting the room or a temporary separate room...

    Thanks for that information, international service advertised on their site so I’ll have to try them.

    i almost asked if you had any spare of these boards, but it would be more practical to save money waiting for the PC blue buddies.

    More THC testing – UVA vs UVB vs near-UV

    I didn’t run the CMH as it’s only just getting cooler so I’ll start using it on the next cuts going in. As I said, I was very cautious on the timing and it was half an hour max because I’d read all this information. I’m quite experimental but a bit haphazard sometimes so I’m sure without this...

    More THC testing – UVA vs UVB vs near-UV

    Yeah, definitely seems nicer. If I hadn’t read all this information I’d have probably used it way too much and destroyed cannabinoids without knowing, this seems stronger and more taste without a proper cure yet. I’m reluctant to try more than half an hour in future, especially as in winter...

    More THC testing – UVA vs UVB vs near-UV

    I certainly can’t say it was a controlled test, but I did a couple of runs of Jamaican dream from clone in the same room with the same lights except I decided to try the Migro uvb T5 on the second run. After reading this thread and not wanting to ruin my crop I used it for the last two weeks...

    To be fair, this kind of spectrum tuning is relatively new, I have one room that’s almost all highlight 420’s as they’re damn good and all the hard work has been don’t to make a great efficiency and spectrum for flowering cannabis. But I still play around in the other room and sometimes get...

    More THC testing – UVA vs UVB vs near-UV

    I remember reading 385nm and 285nm create a synergy like the Emerson effect for trichome production but can’t find it for a link? I have two of the miro grow T8 uvb lights I’ve hardly used as I read this after purchasing and before installing. I don’t think I’ll run them long looking at the...
