Thats interesting. Where do you have that idea from? And is there a way to test it? Ive seen people saying putdoor insects does things to the weed. Tbh every single grower online seems to have some idea, clever or hairbrained, about this, its hard to separate the real deal from the bogus. If...

Ive not seen the type of supplementation i use in any bars on the market. Theres some far red bars and uv bars of both mars and spiderfarmer i think but i find them slightly lacking in some ways. And also very expensive. Another issue is that the effect of the supplemention i use seems to vary...

Weve run cmh wayback when but that was long before we had all these lights. Led would just outproduce them. In any case it would be bulb specific theres a lot of different spectrum CMH bulbs and i kinda doubt youd have such specific flavours that you could recognise it. The way led mono leds for...

We do a lot of blind smelling and tasting of our genetics to evaluate the effect of different spectrum lights in our grow. There are definitely different tastes and smells and by now i can usually "taste" which one of our lights has grown what bud. Its to the point were you taste a pattern; our...

Do you mean like it has 10-25-40-80-100 levels? It just means that instead of a 100kOhm poti where turning the dial changes resistance the dial will switch between different resistors. Im not a 100% sure but i think 0 would be a open circuit, 25% would be 25Kohm and so on. If youre looking...

Peaked my interest so i googled Kant ardis scam and got a thread on overgrow where it was discussed. My biggest take away was that if you read it out loud it sounds like "C-nt are these" made by "con air" manufacturing. On more serious note if it sounds really fake and scammy it probably is...

Id be more conscerned about infrared maybe causing stretch. @MidnightSun72 this is from some time back, did you ever put this to test? Can we have the results lol? Also thinking about setting up time lapse for our grow, would be a nice thing to be able to show off, and also more controllable...

Congrats on fixing up your old light. Id like to point out a take away for the bulb enthusiast loving the idea of changing bulbs all the time: Leds will outlast even their powersource. Imagine you could still use the same bulb even after your ballast gave up the ghost? Though no shade on any...

Im getting confused about the pics of Cat shit, lol. Basicly: - trying to ask peeps online "how much light can i give to my plants" is probably not the best idea. Each plant is a universe of its own and how will we know better than the plant? Also the amount of light you can give depends on so...

Tbh i dont see too much problems with those pics. On pic 4: front plants look like its about to finish (right) or maybe a bot hungry (left). In our grow we generally like our plants to look like the front 2 if theyre about to finish, means that the plant is cannibalizing which is good towards...

My advice is to adopt a babying approach to start with, around 10-15w per square foot and then slowly turn it up and look for usual signs of unhappy plant. Its tricky to give direct advice, each plant is its own universe. The one thing to factor in is your light cycle: if your 24hrs on at...

Re defo for bud size: - im not a fan of general defo but lolipopping and cleaning out sucker growth at the bottoms helps a lot to concentrate growth to top buds. If you really are in perfect conditions, ppfd and vpd, then just try giving a bit more light and food in mid flower. Though check ec...

Unless you compensate with higher light intensity

I think ive seen studies on this: higher yield and longer to finish but somewhat lower quality buds. You can start on 14 and then draw down to 12 or even 11 to make up for it

OP: please consider also that temp and rh have a relationship with eachother. Transpiring plants cause rh to rise and temps to lower. Also, raising temps in summer will lower your rh somewhat as hot air can takes more absolute humidity to saturate. Yes you will need some heating in there...

Youd need someone to do it for you, there several custom pcb makers online or just go with a Alibaba supplier but make sure you get the gerber files to be able to reproduce your pcb thru any other company

The osconic comes both in a midpower white version, 3030, and a larger 3737 version. The next rabbithole is making your own pcbs, there are several services online doing this aswell as the regular alibubbers.

I think arrow has a pricing algorithm, and some items they just tell their system to sell at the lowest price online. Sometimes theyve had ridiculously low prices only to change back in an instant when they realized.

Has anyone found details on the 640nm version of this diode? Cant seem to find any datasheet on it, only the other versions

+1 on diy! Both bars/strip and boards work but id recommend running the boards around 60-80w rather than 120: more boards on less power makes for better spread and lower hanging height. If i open space its worth considering hanging height as +12" means a lot of light wasted on your walls...
