    Co2 and ethylene

    The swings in co2 is to not Inhibit the rubisco enzyme I believe A poster on here suggested I believe to have the controller kick on at 600ppm and rise to 1200ppm,he was the one talking about rubisco activase I believe. I've heard many suggest lower rh for increased resin production and less...

    Co2 and ethylene

    Many growers cut down co2 to atmospheric levels the last 2 or 3 weeks to help trichome maturation as co2 can/will inhibit ethylene production which will cease trichomes maturing. What ppm do people reduce co2 levels to and for how long before chop. Atmospheric is around 400ppm no (slightly...

    When to Stop co2 Increase During Flowering?

    Would you suggest exhausting What's your thoughts on co2 inhibiting ethylene production late flower, atmospheric levels during ripening phase?

    Do you not risk clogging the stamata spraying everyday. I was told every 3 or 4 days to avoid this...?

    Dense nugs

    Lower rh is often touted as a technique to increase density however you may find it inconsequential after curing and water content has regulated. I'd be interested if someone could shed some light.

    What's your EC or PPMs?

    I'll bump it to 1400's during heavy fruiting phase running f&d iws with co2 supplementation and you'll still see the ec drop

    From DEs to LEDs

    I'm considering the switch from de fixtures to leds and being "uninitiated" in the led field this thread was perfect, thanks op. Your comment is comforting as I hope to achieve similar yields and quality with the same wattage in the flower room. Currently run perpetual in a iws f&d/dws system...

    Led vs hps

    Currently have 4 1000w de fixtures and 2 600w Current have 4 1000w de hps fixtures and 2 600w. Run a perpetual in an iws f&d/dws hybrid system with co2 enrichment and harvest about 20 pounds every 10 weeks. My main query is, will yield and quality be comparable with a top end led fixture of...

    Led vs hps

    Are leds comparable to hps and cmh nowadays? I know the main drawback is cost but when I was still plugged in it seemed most commercial grows were still using sodium bulbs and led commercial grows we're very niche. Can someone give me a breakdown of the major cons of led. It seems the biggest...

    Trichomes & Harvesting

    Should you reduce co2 levels down to atmospheric levels towards the end of flowering, as increased levels of co2 prohibits the production of ethylene, vital in the maturation of trichome? Also foxtailing is new growth and thus immature compared to the rest of the calyx and its purported that it...

    Late Pk boosters

    So currently am using shooting powder weeks 5-8 along with bud XL weeks 3-8 but am getting horrid foxtailing. Suffice to say I plan on switching to moab however with a 0-50-30 ratio its (to my. Understanding) undesirable to have higher levels of p during final phases and something like big bud...

    315 cdm Philips bulb

    The Philips bulb comes in a 942 (4000k) and a 930)(3000k) Using them in veg and obviously the 942 is better with more blue but when I was running the 930 they looked alot more robust and generally bigger. I know the increase in blue in the 942 will keep them squat and promote side branching but...
