Calling all COBs, Calling all COBs, come in number crunchers are you receiving?

Hello interweb Cannabuddies,

Just for giggles I have been looking at COB bargains in Europe. I would really appreciate some opinions on a couple of budget friendly COBs I have located here in Europa.

I am attracted to these COBs purely based on their price point and availability in my neck of the woods.

Prospect number one is the CLU046-1212C1-353H5G3 (3500k) also available in 3000k and 4000k at prices less than $4. There are several hundred of these available in all three colours.
Datasheet: http://ce.citizen.co.jp/lighting_led/dl_data/datasheet/en/COB_4/CLU046-1212C1_P3096_0415.pdf

Prospect number two is the http://octa-electronics.com/en/products/light-emitting-diodes/cob-le-ds/c7a-series This company is based in Bulgaria and their pricing for the C7A is around $18(cheaper the more you purchase). If you explore their website they have other COBs at cheaper price points.

Datasheet: http://octa-electronics.com/web/files/product_groups/41/files/Data Sheet C7A v1.1.pdf

I know there are several members here whose number crunching abilities far surpass my own. Many of which actually enjoy this side of the hobby which I must confess is my least favorite pastime.

Any opinions, be they positive or negative would be most appreciated.

Cheers,
Will

How Much Longer?

As a general rule of thumb, if using artificial light;

1- Veg 30-70 days (personal preference / space)

2- when you switch to flower (12/12)
Start counting your time “in flower” at the first signs of flowers forming. This is usually around 2 weeks after switch.

3- start counting up to 8-12 weeks from that time. Longer if it’s a Sativa and chop it when you get close to that time or after.
Otherwise you can get yourself a jewellers loop and go into a little more detail with your plants and go by trichomes. Plenty of info on RIU about that.

Ps cool name!

A Plant Will Burn Up And Die If Theirs Too Much Light Intensity Jesus These Calculator Non Growing Internet Jockey’s Is Really Starting To Get On My Last Nerve

Elongated, stretchy stems are the bane of any new marijuana grower. They don’t provide the seedling, which can end up affecting the plant throughout its lifecycle. But, getting rid of the stretchy stem is really a matter of replanting the seedling so it doesn’t continue to grow disproportionately. When they’re in their seedling stage, stems will stretch out for a variety of reasons, but generally because the light is too high and they are trying to “reach” up towards it. Lowering your lights can keep you from experiencing this problem.

But, first, let’s talk about how to fix the problem if it occurs to you. The first thing you want to do is make sure the soil is dry. If it’s wet, the roots will have a tendency to cling and you don’t want them to be damaged in any way. Then, very carefully remove the marijuana seedling from its current container. Clean off the roots so that there is no more soil attached.

You may want to use a deeper container or just dump the soil out from the seedling’s current container. Leave a little bit of soil in the bottom of whatever container you decide to use so that the roots won’t try to grow through the drain holes. Place the seedling down in the container in such a way that you can bury the stem. It is ideal to bury the stem almost completely so that only the Cotyledon leaves are showing. After that, provide the marijuana plant with just a touch of water to get it going again.

At this point, your stem will be buried and it will eventually start to grow roots of its own. This is something that can apply to little seedlings and even incredibly long, emaciated stems. Again, as long as you’re extremely gentle with the plant, you should cause no harm and the plant will not be stressed.

To avoid stretchy stems make sure your marijuana seedlings get enough light an place them under a cfl bulb (3 watt per seedling). Distance between plant and cfl bulb should be around 2 inch. Distance between plant and HPS bulb should be around 40 inch for seedlings (20 inch for vegging plants) but make sure temperatures don’t exceed 77 ºF.

1P-LSD & ALD 52

ALD-52 is claimed to be what was in the famous Orange Sunshine tabs back in the day. Claimed by Tim Scully and Nicholas Sand who was the source of Orange Sunshine. ALD-52 undergoes hydrolosis to turn into LSD in your body so that’s fine to take

Have also heard good things about 1P-LSD but don’t know too much about it, it has its own properties as well as being an analogue to LSD from what I know, less potent too

Just do anything you feel comfortable with, both are very much like LSD so treat it as any kind of normal LSD experience. Don’t do it in uncomfortable areas or situations and just have fun and relax

Let’s talk Clinton Foundation

Let me help out all of you good Americans and summarize how the Clinton Foundation works as a tax free international money laundering scheme. It may eventually prove to be the largest political criminal enterprise in U.S. history.
This is a textbook case on how you hide foreign money sent to you and repackage it to be used for your own purposes. All tax free!

Here’s how it works:

1. You create a separate foreign “charity.” In this case, the Clinton’s set it up in Canada .

2. Foreign oligarchs and governments, then donate to this Canadian charity. In this case, over 1,000 did — contributing mega millions. (I’m sure they did this out of the goodness of their hearts, and expected nothing in return. Imagine Putin’s buddies waking up one morning and just deciding to send untold millions to a Canadian charity).

3. The Canadian charity then bundles these separate donations and makes a massive donation to the Clinton Foundation.

4. The Clinton Foundation and the cooperating Canadian charity claim Canadian law prohibits the identification of individual donors.

5. The Clinton Foundation then “spends” some of this money for legitimate good works programs. Unfortunately, experts believe this is on the order of 10%. Much of the balance goes to enrich the Clinton’s, pay salaries to untold numbers of hangers on, and fund lavish travel, etc. Again, virtually all tax free, which means you and I are subsidizing it.

6. The Clinton Foundation, with access to the world’s best accountants, somehow fails to report much of this on their tax filings. They discover these “clerical errors” and begin the process of re-filing 5 years of tax returns.

7. Net result – foreign money goes into the Clinton ‘s pockets tax free and untraceable back to the original donor. This is the textbook definition of money laundering.

Oh, by the way, the Canadian “charity” includes as a principal one Frank Giustra. Google him. He is the guy who was central to the formation of Uranium One, the Canadian company that somehow acquired massive U.S. uranium interests and then sold them to an organization controlled by Russia. This transaction required U.S. State Department approval, and guess who was Secretary of State when the approval was granted.


If you’re still not convinced this was a cleverly constructed way to get unidentified foreign money to the Clinton’s, ask yourself this:

Why did these foreign interests funnel money through a Canadian charity? Why not donate directly to the Clinton Foundation? Better yet, why not donate money directly to the people, organizations, and countries in need?

Compare this…… Imagine how former Virginia Governor Bob McDonnell feels.
That poor schlep is in jail because he and his wife took $165,000 in gifts and loans for doing minor favors for a guy promoting a vitamin company. Not legal, but not exactly putting U.S. security at risk.
