wow 32c in a tent using hid will produce just about zero thc. even led would produce low thc at such high temps conversely, 5c / 85+rh in a tent is a recipe for permanent grow tent pm i have experienced both of these things so for now am just toning it down to well timed closet grows

the consensus on mh vs hps was hps produces better yield and mh better quality. mh buds are denser and frostier my original intent when switching back to hid was to get an mh bulb for this light but just haven't checked into it yet. for some reason the mh version of this light is only available...

i came down with yield acquisition syndrome aka yas and had to try the led with the hps. just two bars on 15% dimmer mkay

yes it is true it is all about humidity, but i am not able to keep a stable 90% rh under any circumstances @ charles i don't have any fertilizer it's already in the soil and this brand has always grown good plants under cfl, hid and sun. led, may through august only quite literally the most...

i can't get the light dim enough to not still fry plants 8 months out of the year though the hps is running brighter than the max i could keep the led at so that solves the problem for me so ultimately it becomes vpd, as explained in this rollitup post

hid, cfl and sun have none of these problems so yes, it absolutely needs extreme augmentation. i'm only good 4 months out of the year with this light where i live, ain't no science degree needed with any other light source and yes, they did side by side university level tests and compared the...

it was the bugbee research team that did a video showing how in enclosed grow spaces using hid, thc and cbd makes a sharp decline at ambient 27C and up, the minimum temps that leds purport to require to sustain healthy cannabis and powdery mildew is real where i live so that's another reason...

i've never had a light source demand an extreme augmentation to the environment just to get plants up to health though it would take extreme augmentation just to get the plants healthy for the most part of the year when the environment won't support it. i did get very healthy growth in spring...

i would imagine to run the led and get good plants i would have to go well into the 80f range and boost humidity way up, all to just see if i can get the plants up to a baseline of health, which is ridiculous when i can just plug in a cfl/hid or grow in the sun instead and get perfectly healthy...

and here's one month of hps growth compared to almost two months of led growth notice how the hps plants are way bigger and not all f'd up lookin : ) all i did was swap lights, that's it happy hps plants @ 1 month struggling led plants @ 2 months

some very interesting discussion about led and hid here at 1:05:57

exactly lol

ever seen a mite city, encased in a blob of puss-like translucent goo? well, look no further! apparently the mites really do climb up the plant when you hang them, and in this case they all somehow either made a goo dome to exist in or the goo was from the plant (i'm thinking the former)...

either their standards have gone down in general, or all of the 5 star reviews are correct(!)

for me most times of year plants are likely to look like this ^^ which exactly highlights the problem with my kingbrite. no way in hell i'm pumping heat and humidity at the levels needed to avoid this from happening. the only climate control i need (should need) is just growing in the spring and...

i keep upping the challenge to peeps on reddit to repeat what i did with a 1000 mh with thai seeds in a dry cool concrete townhouse basement fall time ontario and they get all offended because they know white leds cant do that i just switched out the lights from led to hps and plants went from...

can verify that cfl bulbs are also not affected by low humidity and temps like white led's either

which, btw, rendered my kingbrite led a piece of garbage in how it grows plants. not even close
