    R strip Samsung horticultural

    Fair enough, I thought that was different to Emerson, as it’s just a flower initiated that you need like the gromau puck

    R strip Samsung horticultural

    I’m not sure about all that I thought the Emerson was a fixed spectrum. I just bought them as I needed an upgrade and at the price and with the par map they have I couldn’t say no, I only needed the strips as have the rest including the driver from my old rig

    R strip Samsung horticultural

    R strip Samsung horticultural

    just got myself some new lights so thought I’d post and tell people about them and maybe do a diary. These are new R strips from invisible sun with Samsung lm301h and lh351h and initially they seem promising.

    Potentiometers

    just wondering how I can up he resistance in a pot? I keep buying pots and everyone of them are between 90-96k I need at least 99 if not 100+. Iv even gone and bought a Honeywell pot and that is only 96.9k. So can I ad a resister to up the rating whist still allowing it to dim to 0? Thanks

    Ripening indicators

    so since I switched to led over a year ago iv been confused as my plants appear to be ripening faster than ever before, I have amber trichomes popping up and a lot of hairs turning brown but only at day 40. I have been assured this cut goes 63-70 days so surely this is way to early

    Do tube heaters give off ir?

    I don’t see where I said there was. So it has to be actual ir light? Ok. When people say the ir is the reason for the heat I wasn’t 100% sure if the ir heat would have any detrimental effects. Thanks for clearing that up. I did say was probably a stupid question. But no one seems to answer my...
