https://www.ledsmagazine.com/leds-ssl-design/packaged-leds/article/16699036/bridgelux-announces-thrive-series-leds-with-uniform-and-broad-spd Anyone heard of this? Looks like it's going to have a much more uniform light distribution. Is this going to be any good for plants? I can't seem to find...

I have 480W of 3500k bridgelux eb gen 2. They do well. I'm looking at amping up the wattage a bit to 600W max. What would be the best addition? I already have some 5000k veg leds. 2700k full spec LED? A small HPS? Some ~750nm red diodes? Please give your product suggestions with cost and lm/W...

Anyone know where I could get some? Thx

Hi all, I found a 1:1 cbd:thc strain that worked wonders for me. Gave me a very mild euphoria and super clear head, very functional. Can't find anything else like it. It's called Midnight by Tikun Olam. If you have a good substitute suggestion and a way for me to get the seeds in Canada...

Hi all, My plants suffered a significant light leak and hermied. Three I pulled with nanners one I pulled with just barely the beginnings of a seed here and there. Should I cure and smoke these puppies or will they be too weak? I could buy a bubble hash bag and do em up or something...

Hi all, I'm at week 4 of flowering. I used a bag of 0.5 0.5 0.5 npk worm casting and organic fertilizer to pot them up from 2-3 gal pots. They're in 8-9 gal pots. Added a fair bit of organic bone meal crumble 2 months ago. About how long into flower will the dirt last? Am I waiting to see...

Hey all, TLDR: Cloned some mainlined tops, they look kinda delapidated and shiny, some look like they might have tried to flower. Was missing a fan til now. Used some questionable cloning practices and some slightly hot worm casting fertilizer. Running (2) 5000k full spec white 30W LED "corn"...

Hi all, Been reading about adding 5% of your total light as UV-B during the end of flower to boost THC. I'd like to try to achieve this by bringing a plant or two outside for 1 hour a day, perhaps in the evening since the colour spectrum is more red then. Anyone done this?

Hi all, first grow and all. I lost a plant under my LED setup so I stretched the rest of them out into a nice flat canopy to take up the extra light. However, the main colas do not seem to be turning back up towards the light anymore. I bent them sideways with no breaks or anything, just some...

Got these kinda pollen sack looking things going on under one of my buds. They all have hairs female looking hairs sticking out though. Has it hermied? About to produce nanners? Not sure what to think. I did do some trimming of the underside this week (week 3).

Hi all, Long story short I tried mainlining and I'm finding theres too much open canopy space in the middle and the mains are too high compared to the lower branches that are trying to fill the hole. I also read that mainlining is more suited to hps or something less uniform and more...

Hi all, Tldr: led first then hps or Sun second makes a very productive veg phase. As opposed to only going with hps or a more red spectrum when switching to flower. First time grower so I'm looking for opinions, as well as proposing a theory. I'm growing weed plants and tomatoes. I've...

So a flood soaked a Tupperware full of "oops my plant got pollinated by someone else" seeds and so the race was on to do something with them. I sprouted them all and immediately started tossing out rejects or anything that struggled in any way. Got rid of anything that didn't show clear female...

So I'm not an idiot but I am new to electric circuits. I setup 10 luminus cxm-9 (32-37V, 320-640ma, 12-20W) in parallel on a 150W hlg-150h-36A. (32-40V max 4.2A) . I split them into two groups of 5 and put them on two 4" x 48" pieces of 1/8" aluminum, with 3C/mK thermal grease. A theoretical...

I started some mixed seed and worked my way down to some winners. However, they haven't had a great go of it. They were sulfur and phosphorous deficient for the first month and I didn't figure it out until I put the higher power veg lights on them. I also put those lights too close and stressed...

So I never grew a pot plant before and hardly ever grew anything else either. A friend handed me a bunch of seed from an outdoor sativa that he said grew very well with nothing but good soil and molasses water. I tried his weed and I was sold. Decided to start them inside since it's cold here...

Hi all, I noticed that a lot of the builds out there are being screwed, riveted and bolted together. Brazing aluminum is very easy as far as welding things goes and there are a ton of very well explained videos about how to do it. I've linked one below. You just need some brazing rods from a...

TLDR: I need some cheap veg lights for Ma's greenhouse. They need to reach 4-6 feet and provide supplemental sprout/veg light until the summer sun is in full swing. Does anyone know from practical experience if these CXM-9 cobs will effectively throw light that far? Also, 4k is my best guess for...

So I have a decades-old beaver dam full of rich organic compost and I've been robbing it for soil and growing my lovelies in it. Mixed in some peat to give it a less clay-sand heavy composition. So far a few have had their lower leaves start to fade yellow from the ends and a couple had just the...

So I found a genius idea on YouTube and had to spread it. It's how to make felt garden pots with a bag sealer and landscape cloth. A whole 3'x50' roll of “20 year" landscape cloth is 20$. Amazon sells pots for 3$ for 10 from China or like 8-17$ a piece from anyone local and with decent quality...
