Wow excuse me for being rude and firing off questions immediately! Your grow is looking awesome! Im learning a lot from watching and am slowly realizing a lot of growing is on the fly. You may have a plan set in stone but you never know what will happen(guests, malfunction,pests,etc..) part of learning to grow is making those mistakes that you had totally left unaccounted for but wont happen again. Its a learning process that never ends as technology improves and I have seen people who have grown for as long as ive been alive talking about how they learned something new just the other day. Gah! I jus rambled. But your girls looks excellent and you are doing a fine job. All the best.

G4P, I set out to prove that there is no right/wrong with leds other than the very basics;

make sure to use 5000-6500K for vegging

and 2700-3200 for flowering.

During flower the B/R ratio is ~ 10/90,

lumens ~ >90 lumens+/watt

If you hit that loose lighting parameter, and have good grow technique, you should be golden

I do not have any experience with green bulbs for night work

Hurray

Buds are fattening up fast now that I have reduced night temps

Also, soaking 5 G13 poly cross seeds. These also went through washer/dryer, so fingers crossed

Hi people, first post here :). what is ideal? 2700k for flowering i know yes.. and 6500k ( or 5000k? ) for veg?. Would it be bad to offer cannabis plants 2700k/6500k ( or 5000k ) the whole veg and flowering period?

And.. Which of all the led tubes and led bulbs are the very best? Ive read all 31 pages of this thread. The philips down led bulb on the youtube video had more than 2000 lumens . Ive also read that cree xpe 12w is good. But which lamps are NOW the best a man can get for cheap growing?

found this

30W Cree XP-E White 5000K Waterproof XPE Flood LED Light Lamp Bulb AC85V~265V
http://www.ebay.nl/itm/370680615884

thought it was cool. Bit expensive

thanks

G4P,

Somehow your message about buying tubes did not make it to my thread, but I did get it in my email WTF?

Anyway, yes you must call. There is a $100 minimum which is only 3 tubes anyway. FYI, I have seen plenty of tubes that are no where near as good for >$60, and plenty ar >$70

Seriously? I am just 18 years old you cant talk like that to a stranger. i mixed the frequency and corrected my first post.. Please give me advice :) . 5000k or 6500k for vegging? Or both? And which tubes and leds lamps are the best for this?

My advice is for you to actually do some reading. My thread, as well as many others under LED Lighting, answers your question hundreds of times

Why not show some love sir? 5000k/6500k? In the beginning of this thread you say 5000k later 6500. is there more blue spectrum in 6500k? Or does 5000k have more par? Please be helpfull and not a dick. Thanks

If you weren't too lazy to read, which is painfully obvious, you would see how helpful I am.

That said, I feel no responsibility to spoon feed you regarding the most basic of information.

Buy some books and read them. I did

Hey there. Welcome to the forum. I'll get off my high horse and offer something. Some people class 5000k as neutral white...some as cool white...it doesnt matter...4500-7000k will veg some plants (and help in flowering) we shall call it 'white'...so it doesnt really matter what kelvin (K) white you get in this general range.

Petflora: Why are you considering putting that UFO back in? You mentioned something about adding more 660nm...which i thought you were against?

Little calyx development...lack of penetration from those weak individual tube diodes...i did tell ya... :)

For me, part of the led learning experience is to see how low I can go with leds. Any lessening of yield is not a big deal as long as the end product rocks.

I do plan to add ~ 45w before flower for next grow (no luck so far finding a US dist for 2400-2700K tubes), on my way to adding sufficient umols^m2 to max out yield

Don't get me wrong, there ARE tons of trics on buds, primary leafs and stems >15" below the tubes!

Oddly, they seem better defined than the trics from identical clones under my last grow with 324w HOT5, which was ~ 90% red heavy; 3 UVL RedLifes + 2 Zoomed Fluorsuns + 1 Coral Wave

I put the ufo back in on one side only wondering whether the extra ~60w of red would kick start and fatten up the calyxes. So far, I see no change on the ufo side, but the pink light can be deceiving. Will check outside the tent tomorrow when I change nutes. Comparison pics of course, but my camera dos not do macro

Yeah, magnets won't affect your pH. You'll need to add acids or bases to do that. Temperature effects on pH are also minimal in the range that plants can survive. I wonder if anyone has thought about, or tried experimenting with different buffers to help maintain constant pH.

Ill give you one guess...

give up?


Phosphorous, which growers are known to abuse during flower

Keep in mind my buckets only allow 2.5g below the bottom of the net pot

In 5g rezes I suspect it won't be skitzo every 2 days

I received a copy of this in my personal email at 5:10, but it's still not posted though others later were

Bumping Spheda has just replied to a thread you have subscribed to entitled - LEDs Stripping Back the BS. Vegging 6 Clones under 22 Watts - in the LED and other Lighting forum of Marijuana Growing

Here is the message that has just been posted:
***************
bloemetje: 5000k and 6500k are both veg oriented. Yes, there's more Blue in 6500k, this is _inherent_ with a higher CCT. The higher the CCT the more Blue-Green there is and the less Red-Yellow. This _does not_ mean vegging plants don't like Red. For veg I recommend mixing 4500k-6500k and 2700k-3500k. For flower you want 2700k-3000k and probably some added Red (630-680nm). I give ranges because, believe it or not, you shouldn't see a huge difference in plant behavior anywhere within the ranges I provided.

The reason why people are "being mean" is because your questions are painfully obvious. He's not being mean, it's called tough love. You'll be happier if you educate yourself more. Trust us.

GL, HF and stay safe.

Why you calling me out, man?! xD

I came in and said that, then saw there was a whole next page where you and Chron pretty much addressed the issue so I felt douchey and deleted it.

Meh. As you were, gentlemen.

I think/hope you replied 'tongue-in-cheek'. I felt your post was valid, especially this part

The reason why people are "being mean" is because your questions are painfully obvious. He's not being mean, it's called tough love. You'll be happier if you educate yourself more. Trust us. and Chron, trying to be helpful, bailed him out

and since I had a similar experience earlier (where a post made my in box but not my thread), I thought the site had gremlins

I almost added to my second reply to blowme If you give a man a fish you feed him for a day... but feared he wouldn't get that either

Just changed nutes ~ 340/6.0

Can't see any sig difference between clones with ufo added, BUT, it was added very late, so benefits likely negligible

I think he's selling his own line of hydro nutes now so the hydro was probably grown under ideal conditions and the soil was a bag of cheap soil under not so ideal conditions. He talks about the hydro conditions but never says anything about the soil,what kind of soil or if he's feeding the soil plant any nutes. I know hydro will out grow soil but that doesn't look realistic.
