what's wrong? I think I gave it too mich nutrients, I'm using flora trio but bit more than recommended but it only showed sines now, is it overfeeding/overwatering or is it deficiency?

medium is for flowers I dont have access to coco locally so I use what i have to :D but plant is getting worse no idea why I reduced watering and let sodium dry really well. I dont give nutrients yet my onlu consern is that temperature goes down to 18C. other than that I don't know what may be...

ultra white amnezia from minitstryofcannabis. plant is 3-4weeks old and leave stems are purple and in first week or so first two bottom leaves yellowed and fell off (maybe overwatering). also leaves are stiff but small tips are upwords and have bit brown, looks like nutrient burn but I gave very...

but how much? is it still viable? if i do so and try to measure heat most likely second top heatsink will be cook but maybe because it doesn't transfer heat well enough. can I touch led surface?

thermal paste doesn't reduce heat transfer? got idea from this video to glue 2 heatsinks

this kind of coolers. I don't like active cos of sound, it should be stealthy :D so another idea i have is to use 2 this type of heatsink and glue it on top with thermal paste in theory it will double area but I'm not sure how good is thermal paste join, will it transfer heat good enough to top...

I'm talking about intel default heatsinks can it be used as passive heatsink for 50w? has anyone done it? I don't have equipment to test it or do some advanced sht :D any experienced users?

so using cpu heatsinks for passive cooling is bad idea? :D i got clu048-1212 working on 1400ma so can cpu heatink cool 50w led passivly? I'm goint to use cpu cooler with fans but really don't like fans it's noisy

you don't need that much height its 1.5 meters right? if your going for cfl-s. cfl has very low penetration so 1 option is to use 40w cfls and mount them on sides along the plant. 125w cfl wont do you anything it's better to use many small cfls because cfls cant spread/penetrate light on long...

is this legit? :D I can get free pc coolers and if I glue it with thermal glue (or bolt ) on sheet of aluminium does it act like single unit or does thermal paste joinery lose it's efficient so bad that it's not gonna work? its kinda free gather old cpu cookers and glue. is it worth the effort?

can I use hlg240h-c1400b on 4 cob?

used local nutrients, for flowering 11-35-11 npk and from now on I'm cutting it off. it had some problems with nuts and overwatering that probably slowed it down but now it's okay and let them grow for next two weeks after that I'm getting over with it if there was no potency gain. interested...

I'm ordering driver for 4 CLU048-1212 80cri 6gen and thinking about hlg240h-c1400b. question is to make sure I'm getting correct driver, it has 89 ~ 179V and cobs work min at 31.8- 34.6 - 37.5 so 4X 34 = 136 that should work with driver right? but I noticed that someone uses 5 cobs with this...

clfs are 2700 total of 250w and 1 50w 3000k floodlight. plant smells a bit, when I dried it in stove it smelled really good, it's really sticky but not potent. I'm curious how much will it gain in 2 weeks. i don't think 2 weeks enaught for potency gain

I'v switched it to 12/12 after it showed some hairs on 6th of january and it in 10th week of flowering. couple days ago tasted it and got nothing at all. quick dried it smoked. trices look like 80-90% are cloudy with little to no amber 1-2 amber trics. I was expecting something out of it buds...
