mg may contain lead and arsenic in their mixes, that's why it's for ornamental plants, not food and especially not medicine crops. i hear stories of fungus nats coming from fresh bags of their mixes too. their basically junk dirt and some time release ferts. their organic line is slightly...

true, but the biggest issue i've seen with the higher wattage diodes is shortened lifespan, especially with the cheaper units as they tend to overdrive the diodes. again i think they will have a future, but i think they really have to figure out how to make them far less expensive, and more...

i've rarely been impressed by any purps, regardless how it was grown or where it came from. it's not always true like i say, that jalapeno is amazing... it's like a roller coaster ride it starts like a pure intense sativa for around 2 hrs, then almost instantaneously changes to pure indica...

if it's a hermie due to genetics, then you can't fix it. if you really wanna keep the plant around you could pick off every male flower on it, but you'll probably miss a couple and end up with seeds anyway. i'd start with new seeds if possible.

it may be beneficial, i've heard mixed things. i'm certain it provides no benefit after the roots find the water, but i do know a couple people who do similar setups with top-feed lines feeding them till they reach the reservoir. my concern would be that the roots above the water would not be...

in a few more years when they're more cost effective and reliable, they'll be far more practical. they are unquestionably more efficient watt-for-watt, but they still need better penetration and a larger footprint to impress me. then they need to cut the price in half or better

i hear the power supplies are a common failure as well though as they're one of the parts manufacturer's cheap out on

in a home-grow. in a 5'x5' area, if i had a single 1000w lamp in let's say a common flood and drain system.

dimming a light would be difficult. a better option would be to have a light mover, so you can cover more space with a single lamp, or if you have multiple lights you could get a ballast flipper so only half your lights run at the same time, then the flipper will change to the other light it's...

MG will never be cheap enough or advertise well enough to convince me to ever use their products again.

i have to say, with how much everybody raves about the success of different cloning machines, i've been the most impressed by rockwool cubes, with plain water. no flooding when a nozzle turns the wrong way, clones don't die when a jet gets clogged, and i get a better success rate... all while...

so by what you've said, instead of buying the $1200 stealthgrow 300w LED, i'm still gonna need 3 of those to match my HPS yields? so my 1000w light which i could've found on craigslist for around $100-$150, and costs around $30 extra per month on my bill ($360/yr or around $2k in 5 yrs, + $500...

some plants are also just genetically purple... i had this one called jalapeno, and even in the peak of summer, it was a crazy mix of purple red and green, even in 85' F days and 70 F nights. also it was the only purple weed i would ever grow again lol purps to me means bad weed usually. GDP...

out of my own curiosity, i've decided to try this experiment myself. so far, after 3 days of 12/12 on only one branch, it's actually looking promising. i have at least noticed a couple of the budding sites starting to flower, and it's already producing trichomes, and it's still in my veg tent...

repot and make sure to water often enough. they look pretty under-watered. if it is a disease i haven't seen one that takes on the whole plant like that. i've seen fusarium, which is incurable but doesn't kill them like this but a single branch at a time. best you can do is repot and hope they...

let's think about this. say you have a big warehouse, like 2000 square ft., and you need about 30 lights to cover the whole room. are you gonna spend $ 9,000 on 1000w hps, knowing that NO LED can touch it's yield, or are you gonna gamble and spend $90,000 to get the most powerful leds, so you...

yeah nute burn all the way. it also looks like you have the beginnings of a mite infestation as well

it wasn't that fresh. it had been in the pot for around 3-4 weeks, and was looking stressed from overfeeding, so i flushed the 3 gal pot with a total of 5 gal. plain water, and it took a couple days to recover but it seemed ok. i haven't used mg since so i can't say i know much about the time...

i'm not saying led's won't have a future in commercial gardens, i'm simply saying it's a ways off. even if led's have come a long way in the last couple years, hps is reliable, and led's generally aren't. yes there are a few company's that stand behind their products, but the cost for the...

if it was covered by another plant's leaf, it's not full darkness so it probably wouldn't work. i can't say i've ever put a single leaf or branch in a black box or cloth to provide full darkness, but i see how it could work. the plant produces it's flowering hormone when it's dark, so causing a...
