Well I am no photographer, but for me I just had to see the bleaching to believe it. Something about the discrete wavelengths of these LEDs must be overdriving the photosynthesis to deplete those nutes. Just gotta tweak the process a little I guess. Another good sticky-icky strain. Due to a...

This is RP Kandy Kush (almost done) in hydro and I have had her within an inch or two of the Blackstar 240 for most of her adult life with no problems at all, and producing some of the sticky-ickiest bud I have ever grown. It is only the new growth, right up against the LED, which has been...

I am seeing LED bleaching for the first time and the white growth looks like a lack of chlorophyl, which I think is an Iron deficiency (chlorosis?) Does Cal/Mag have Iron in it?

Lumens are for humans, and are not useful for plants. For flowering 33 sq ft, you are going to need upwards of 1,000 true LED watts at a minimum, costing maybe $2,000. But I think that to be truly happy, one needs about 50 true LED watts per sq ft for some serious flower power.:blsmoke:

Yea, I hear ya, as long as the fans and the lights work! Thanks, that's what I wanna hear!

I got my Blackstar on ebay with free shipping in the US. I am starting to suspect that LED specs can be misleading. The Spectra users seems happy with theirs, too. Are you doing side-by-side grows with your LEDs to compare? I don't hear anybody complaining about their Blackstar and I like...

I think the trick is getting the right PAR in the right wavelengths, so it might not be accurate just to compare watts and lumens, since each different-colored LED is going to have different characteristics (at least that's what I got from looking over the CREE datasheets, for example). And each...

Thanks, I could not get the attachment to open. I just realized that the Pro-Gro uses 1w LEDs, so not that one. Comparing the Blackstar and HTG specs, I am guessing that the Blackstar might be better for flowering (and it is sold as such). I would prefer a longer warranty than just one year, but...

I am finally ready to spend a little money on LED for a 2'x2' cabinet (to flower 2-3 Indicas about 24" tall). I think a UFO with 3w elements is the way to go, but I am not seeing a clear winner when it comes to price/performance. I do not need Veg mode, so I don't want to spend extra for a...

before I forget, I am thinking ahead to a replacement BNC PH probe and I am curious if anyone has experienced good quality with any particular model? Thanks!

this is just a controller (and a probe), so you still need pumps, lines, solution, etc. the controller is just the 'brain'. I have found very little information about PH Controllers in general, so if there is any interest, maybe we can improve on this? I have the Pinpoint PH Controller. I am...

Got my BF LSD + Attitude promo beans today, took about 14 days. Usually takes 9-10 days to reach the midwest. In case anybody else has been checking their mail obsessively. :blsmoke:

Exactly. I work, so I don't have time to learn how to become MjGyver with nutes, but I can afford to buy what I know works. And I'm a lazy stoner farmer, so I need things simple. Besides, you know how it is once you get that shit dialed in! I ran out of Big Bud once, and it was obvious that my...

I have been using AN Sensi and Conni for my bloom nutrients with Big Bud and Bud Candy in my hydro res (~600ppm with ~150ppm tap water, not too strong). I am interested in organic and I want to try Iguana Juice. I just do not know what to do about the BigBud and BudCandy? I really like Big Bud...

True Dat! If I had to pick only one sativa, it would probably be Serious Seeds Kali Mist.

NO SHIT. This thing is taking FOREVER!

I have a jar of this stuff that has been curing for a few weeks now. Every now and then I get a nice waft of skunky aroma. I have been able to maintain ~75% humidity no problems; seems to resist mold and handle warm temperatures well. Potent smoke, I was impressed. Medium creep. I can't even...

I hate you. ;-) at least until the next Attitude offer when they will hopefully be back in stock. :weed: I hope you forget to flush and you cough your lungs out. :finger: nah, just kiddin, enjoy the smoke!

By the time I got home from work to place my order, it seemed like a lot of items were out of stock--like there was a mad rush or something to place orders earlier and stuff was getting bought up! :o anyhow, I have been wanting to try it, so I ended up getting some of the GreenHouse...

Confrontation It's like virtual paintball. Easy to learn, hard to master. I love it and hate it, so it's like golf for me.
