    1000+ for a decent one , the cheaper arent that good.

    Use a bit of theory and you will be fine with just reading the plant

    Very roughly Herb but there are some very helpful, expensive par meter owning people online working out the coefficients for each light. Migro put up a few on his channel.

    I thought I’d get away with this but apart from not knowing about collaborating my lux meter it’s different for different light kelvin’s and that.
    I’ve been looking but I think it’ll be cheaper to try make one but then it’s still the collaboration

    Hlg have a lux meter to par conversion chart on their website.
    https://horticulturelightinggroup.co...ng-lux-to-ppfd
    For hlg boards divide lux by approx 65 to 70 for par.
    But do be aware this is only for the lux meter they used and will always be an approximation. Migrow has linked an affordable lux meter from amazon also if you don't have an android phone. Which does convert very accurately but only up to around 40k lux.
