I think I found what they are, anyone had Springtails before?
Looks similar but I can't see the underside..

This is the bugs I have:

That's all that I can find that look anything like what I have..
I have caught thousands, the hydrogen peroxide just pissed them off..
Need a safe soil drench that will kill these bastards and not hurt my plants???

If they are Springtails they are supposed to be beneficial to soil but no way, there are too many and apparently breed by the 10,000's

Nice job on the detective work. :goodjob:

ok, here is the answer.

take blue color as example:
The voltage is fixed, chip factory decided, it is 3.2~3.4V. we can only change current to change wattange. while Epistar suggest we use 700mA.so 2.48 is the max wattange we can make. the chip size will decide how bright the light is . 3w chip is 42ml, 5w is 45ml. ml is the unit of chip size.

Thank you Sara for your answer! Much appreciation!

thank you Sara. couldn't have done it without the led. and another thanks to the rest of you here for helping make the choice so easy with your reviews and beautiful journals, giving proof that we're on the forefront of technology for the craft we love so dearly

Nice work PM. Can you share with me the measurements of the outside border of your screen? Also how big your squares are?

I very much like your setup and want to ensure my babies get at least that much space per plant as well.

Thanks!
 
indeed I can. my screen is 24 inches by 22 inches. the squares are 2 inches. I wish I had the room for two plants, but will have to settle for what I got. But I was surprised how much screen this plant took. Topped and lst'd, and I didn't put the screen over them till I started flowering.
 
I sleep from 2 to 7am, and am doing this all day. I love being a stay at home dad. I do love the idea of scrog, but it's a pain in the ass to water them when they get bushy. Defoliation is your best friend in scrog. Helps keep temps and humidity down too
 
I wanted to let everyone know what a pleasure it was working with Sara. I ordered two panels. One was the standard layout and I received it in less than a week. The second I customized with my own ratios and layout and I received it in less than 2 weeks. Sara responded to all of my emails extremely fast, usually within hours (although I do work hours closer to her work schedule than most) and never more than 6 hours later. She provided me with all of the information I requested and everything arrived in perfect working order.

I have a feeling we will be doing more business together in the near future if I can get my schedule to work with me and get my testing done in a timely fashion.

Again, Sara thank you for all your hard work, professionalize, and fast response times!

I'll try to assist in clarifying if Sara doesn't mind.

When labeling diodes, manufacturer label with the max drive current the diode can operationally handle. A 1 watt diode has a max drive current of 350mA, 3 watt is 700mA, and 5 watt is 1A or 1000mA. This is the max drive current at optimum conditions. In the real world, if you run these diodes at the max current on a panel with 50-250 diodes all attached to the same heat sink, you can easily run into something called thermal runaway. In layman's terms means, as the diode heats up it draws more current or voltage (depending on how the drivers are designed) to maintain the light it is producing. This causes more heat which makes the current or voltage raise more. This continues to happen until the diode overheats and burns out. When this happens (without going into electrical engineering design and way to prevent it), it causes all of the other diodes on the circuit to get more power and then the cascade of catastrophic failures happen.

So now we know how they are labeled, we can also look at how to fix some of these issues. We can add larger heat sinks and more fans, both of which cost a lot of money from a manufacturing standpoint. OR we can reduce the drive current, lower the heat produced, increase the life of the diode, and make the panel cheaper with lower weight, shipping cost, part count, and heat sink thickness.
 
Well, I seemed to have knocked these bugs back (for now)...
Ended up giving them a drench of Pyrethrum and using GardGrow pest spray in the Corners of the floor of the tent

Killed a few thousand I reckon!! Can't see any moving today...

My babies are starting to look bad now, my pH is fine, run off is fine but I am getting bad rust spots..
Not sure if it was the Hydrogen Peroxide the other week or from Pyrethrum?

Here they are today, the middle plant at the back has the worst spots on the fan leaf visible.

Hopefully it will fix itself

That looks like it. Don't ever use soil from outdoors for your inside plants. (if you did).

Hey MarkC,

It was premium organic potting soil that I was told when purchasing that it was sterilised... (Lying bastards lol)
I'm not going to let it get me down.. I should have the problem sorted in the next few days..

Killed heaps with a soil drench, ordered some DE for top dressing.. That will be here next week..
That should take care of the problem!!

Oh Good Luck!! sorry your having such an issue. I just hate bugs. That is the only really good thing about growing during the winter instead of spring and summer. There are not near as many friggin' bugs.......:circle-of-love:

Yeah bugs suck alright!!!
If these are springtails, they can thrive in winter apparently... And are world wide.

I'd never heard of them before this, to look at by eye they appear to look like a flea or similar
 
Just got the 2X 96X3W Reflector lights I ordered on Sunday today, 3 days from order to at my door :) :thumb:

I will be using the 96X3W i had for a few months in a side by side with another light from someone else to be doing direct comparison. Unless Sara wants me too, I will not name the other manufacturer on her thread, but it has 100 3 w diodes so should be good comparison, and it cost more then twice as much.

Also you can take a blue hose and run it from your top of pot up the plant and threw scrog net and use a funnel on it to water plants.
 
I'll have to get some hose that's for sure. I was using a funnel taped to a turkey baster tube, just cause its all I could find around house lol. next grow I'll have to make sure and plan ahead much better.
 
:high-five:

hi, Hoseb! hope you have a nice grow with these lights! we are friend, i also hope we will have a further cooperate in the near future!:high-five::thanks:
