Northern Lights + Blackberry Kush Coco Grow

Hey guys, the blackberry kush is really catching up with the northern lights now! Pictures tomorrow. We've also got a side-project with three outdoor durban poison clones in three gallon pots in coco & perlite. We experimented with our supercropping skills today on them. They were given to us, and as we have no room in our indoor garden for such a sativa strain we're sticking them outside, pretty much with the basics to see what happens.

So who knows about grape juice? We've read some articles on grape juice (extract) being a good organic potassium-booster. Can anyone back that up? Thanks for the input.

When you gonna come share that shit?! LOL

Transplant success! And durban poison.

Hey everyone. So we use a T5 6-bulb light for veg and switch to a 600 watt hps light to flower. But people say that UV rays are important as well for increased THC production and potency. HPS lights emit no UV. So we're wondering if anyone knows if T5s emit UV and how much?

Not sure about a t5 ... But I know a black light does. http://en.wikipedia.org/wiki/Black_light

Black light bulbs emit very little to no uvb which is what we seek... They are merely colored glass which allows uva out which is what fluoresces the neons of black light paints....No appreciable uvb... The above is designed with different glass formulation as well as the phosphor blend to produce the correct amount of uvb

Regular t-5's do emit some uvb but not enough to cause the reaction you are seeking


Start them at 40" from the plants and carefully and slowly move it closer...be careful though as it will burn the crap out of your plants if too close

Also look into CMH bulbs

Hope it helps

Nice, good info! Do you have an opinion about CMH bulbs? I was actually thinking about switching to using one...

No digis except for one truly expensive unit by GE

here's a great deal on a mag coil setup...is what I have and I love it

More cmh info than you could need...lol:

There are vertical versions as well as horizontal: there are also some out for regular metal halide ballasts

Also you do not want to use them in sealed hoods or cool tubes as the glass will block the uvb produced which we truly want for potency accentuation


Hope it helps and I love my cmh setup

Is a Hydrofarm T5 still considered regular? A 4x4ft room would need around 160 watts of UV light... so how many of those petco bulbs would be needed? Thanks for the info.

No worries all the information is good.

I do not believe it takes that many watts for uvb production...it is a low amount which triggers the increase in thc delta 9....I have 23 watt cfls 10.0 uvb and at 20 inches it will leach the green right out of the leaves... too high an amount will decrease yield as well....and 1 or 2 inches is a really big deal with these....it is because of the uvc...at 20 inches with the 10.0 I have it is the same level of uv as high elevation desert sun....exceeding this causes the chlorophyll to breakdown....so IMHHO 2 uvb t5's would be plenty....

How did you come up with the figure of 160 watts of uvb bulbs to be adequate for a 4x4 room...in my experience unless mounted very far away from the plant it would hurt rather help

Namaste'

ps- you have a link to the bulbs of which you are speaking? Ok found 'em

Yes they are regular t5 ho 6400 k bulbs....they are produced with regular glass and phosphorous so they emit very little if any usable uvb...regular glass blocks uvb at greater than 99%

There is an "ask Ed Rosenthal" column in an issue of West Coast cannabis, and he mentions that a 4x4ft room would need about 160 watts of uvb light. That's only one opinion though, I know that less is more. How many of those cfl's do you use?

I use 2 23 watt 10.0 cfl's at 36 " from plants in a 22"x44" closet grow....Ed gets caught up in a lot of hype due to influence of the almighty dollar so I take his "knowledge" with a grain of salt. I am going by my experience and have burnt the crap out of plants at 20" with these...but can also share that it definitely does increase potency

Thanks man that's some great information. Yeah you have to read between the lines with a lot of these magazines, all the articles try to get you to use another product.

Yep the old without this magic you will fail...works on the noobs that want to pour dankness out of a bottle or plug it in and boom ...awesome bud...we all know that is not so...it is the totality of proper environment that allows the genetics to show completely... no one thing but all things is the key

Alright... these pictures are a few days old but we'll keep taking more. Next to not being connected to the internet for the last two weeks, our light started giving us trouble yesterday. It would turn itself off, then on, then off, etc about every fifteen minutes. We use an electronic 600 watt ballast and an EYE Hortilux 600 watt bulb, and this was only the bulb's second grow. After trying a different ballast we figured it had to be the Hortilux even though those are supposed to be top-of-the-line. So our hydro dealer gave us a Lucalox bulb and everything is cool now... so fuck Hortilux and their expensive bulbs. They're unreliable.

Here are the pictures, along with a look at the Durban Poisons. :]

Yeah digital ballasts operate on a different frequency than magnetic, which can cause flickering, or what you experienced.

I started using CAP Digilux enhanced-blue spectrum 600w HPS bulbs and couldn't be happier with them.

Hortilux is another ripoff aimed at the uninformed

Cheap ass chinese bulbs are all you need...all that eye sunmaster stuff is bs hype IMHHO...cheapest least expensive hps 600 you can find will work just fine...also due to no bulbs were designed for the higher frequencies of digi's I wish to let that mature a bit so as to allow the bulbs to be built for it IMHHO

Plants look great as always...you girls are really growing green thumbs

Namaste'

Damn, sorry to hear about the bulb. ..your plants are looking nice!!

On a related note..as long as we're discussing lights and such.... I currently have a 400w "AgroMax" HPS light...however, I just picked up a Phillips 400w "Retro White" CMH bulb. I've heard nothing but great things about CMH, so I figured I'd see what the fuss is all about...plus from what I hear it doesn't put out as much heat, while also putting out more lumens, plus it's designed to work with my old ballast. . Anyone here have any thoughts about CMH ? ( Sorry, don't mean to hijack the thread! )
