im wondering about how the meanwells have higher efficiency (96.5 vs 94.5%) but lower power factor (0.97 vs 0.99) at 230V vs 115V when we look at the reality of *billable* electricity does the increased efficiency at 230V just get sucked up by power factor anyway?

also worth noting that: as light intensity goes DOWN, gpw goes UP. as light intensity goes DOWN, g/SF goes DOWN. its by no means an absolute yardstick some people are limited by space. others are linited by electricity, waste heat, cycle time, plant count, etc etc

huge factor when considering all the veg wattage put in over longer days

sort of true. a well managed HPS garden with t he right strain can easily pull over 1 GPW and a poorly managed LED garden with a low-yielding strain can pull under 1gpw if you are getting 300g with a SE HPS, id expect 400 or so with the best LED and same technique

alright, found one in the top shoot of a just-starting-to-flower top now its personal! whats the move? sticky traps? im not gonna spray since im already into flower but would a azamax or spinosad dunk before next flower cycle be useful?

some OLD wisdom from Ed and Mel from 30 years ago that always stuck with me "slightly woody clones root the best" "2 and 3 node cuttings root the best" "do not fertilize with (excessive) nitrogen before taking cuts as plants who have stored a lot of N root slower (i would always feed mom bloom...

yeah i gave up on the cloners. can go so much faster with wool and get a higher percentage (close to 100% though i pitch the slower ones usually)

temp def important. some strains are harder than others. even in cold temps i usually see roots at 3-4 weeks tho 30W 4 feet above is really low light, i usually use the 15W LEDs (with the dome popped off) 12-18" above a tray (or put the clones down low in an existing veg room with ample...

we do ship to EU but drivers get expensive chips/holders/etc arent too bad which hlg-320 driver?

its personal preference keep in mind many peopel dont even have a light meter and in most cases 4 boards are not gonna cover as uniformly as 9 cobs...

not sure about green genes, was probably answering some question where someone was claiming one chip is dramtically better than another and he was tempering their expectations in reality difference isnt hugely dramatic vero C,B, and D are all completely different chips that share the same...

id disconnect it and get it out of the hot zone. run 12 or 14 ga up to your array. mounting it right by where the heat from the nearby heatsink is conducting to the driver case is prob inhibiting cooling

yeah i didnt see any effects on the plants when i saw them on them, seemed like they were just chillin on some fan leaves for fun. figured id ask just in case!

pulled out some winter clothes from a room i was vegging in awhile back. have seen these once before hanging out on fan leaves, just a few, seemed harmless at the time i have a feeling they came in with some cuts when i squish them they have a distinct smell that i cant quite put my finger on...

hes in a larger open room. those are 9 luminus on 3 x 185-48A's i beleive. if i recall topshelf's canopy goes a little wider than 3x3 and is closer to a 4x4

provided they can handle it... and youre filling the space when they are freshly rooted you could probably fit them all under a 600 for 2 weeks or so. no point in blasting 1000W on a 3x3

time to re-up is the calcium nitrate "LX" (blue and red label) same as their regular calcium nitrate for our purposes? from the descriptions they add some chelators? looks like they phased out the old calcium nitrate (blue and green label)
