    Still no independent review of the GeekBeast Pro???

    if theyre ESP based, which i guess, you can consider seting up a homeassistant enviroment and try to flash your module with the help of a USB UART adapter with ESPHOME, if you just need some PWM outputs it could work out.

    RQS Gorillas under Leds

    still brigelux eb3, lots of them driven very low, plus some 660nm on a extra channel did the main job here. so far i see no point changing them to anything else, was a good buy.

    Need help amending soil mixture

    oh, when you ordered dolomite lime i doubt you need normal garden lime also. may just get a bag of dolomite, its long ago that i bought it, but would prefer due to the very good Ca/Mg ratio, could be you dont need the gypsum either.

    Need help amending soil mixture

    oh, cool, you have a soil pH probe allready, so youre fine of course. i thought of these 10$ pH soil test kits who give you a rough idea. thought theyre usefull when dealing with larger batches of unknown soil. lots people use these tests in their garden to determine how much lime they need...
