Leds and distance

l keep hearing of feet away from light, lm an inch guy. Put ladies in flower and dropped light to 12 inches as suggested by manufacturer. Dim to 50% or veg plant will freak. An 8 inch cut will be 3 to 4 feet tall depending in strain, l only raise light if girls say so. These are about second week and 6 inches away from light. If there were more ld give it too them. Light rated for 1482umolm2s so about 1080 usable umol. Homemade co2 helps with intense light, l got light because a very good grower couldnt figure it out. Or l would still be fighting pm with hps. Kept 1k in cool tube venting by 4 inch inline 192 cfm think, full blast, 8 inches from top of canopy, always different sizes no even canopy ever. Pm was a constant. Now the girls look happy. And light hungry, by the way they are praying.

Have you measured the CO2 concentrations with your home made stuff?

nope just counting bubbles, 6 0r 7 a second each is 1cm3 so its getting up there. If we think in ppm. Im probably around 1300 approx maybe a bit lower. At plant canopy. Have a small mcgyver fan that pulls co2 from floor of tent up into canopy.

I've never made it myself but everything I've heard is that the amount of CO2 produced isn't worth it. Did you buy a kit or doing it fully DIY?

wouldnt want to drink it, but run it into shine and shell burn blue. Found filling up 15ltr water bottle 2kg sugar 3 yeast packs and a squirt of ketchup. Run into full waterbottle. Does way more than trb, spelt wrong they only bubble 3 to 5 days then dead for 40 bucks

What's your method? I recently got a cheap air/CO2 meter from Vivosun.

5 weeks in almost, lost count, furthest along.
