Thanks for that. As I understand it, the CXB3590 and 3070 are both 36V COBs, so wouldn't the HLG-240H-C1050 also run 7 3070s? Or is there something I'm missing? That would be ideal, driving 7 per driver. but I can also run them hotter and pick up two 240H-C1400 and one 185H-C1400.

What driver is suggested for 14 - CXB3070s? I'm wanting to run either 1050 or 1400, but I'm not sure there is a driver I can max out efficiency by maxing load. Should I just take away two of the LEDs so I can drive 6 per string?

@bassman999 Which of those numbers tells you the watts being emitted from the COB? As in, how many watts emitted by a 3070 at 1.4 mA? 3590 at 1050 mA? I know it's a simple question.

Wow. That seriously started to direct blood flow into the tip of my penis. That is an incredible collection. One day....

Just reposting this to see if anyone would take a stab at a good mix with the ingredients above?

It's strange to see "bioengineering" in the company name. Comes across half-baked, ha ha. I've worked with a number of bioengineers and I don't intend to pigeonhole the term but it's usually used for a different field of work. I suppose we can broadly use many terms, so we'll chalk it up to...

Wow. How long did that thing veg? What was final weight? That is a beautiful monster plant.

If you are asking me, I though many people were suggesting to add it to the soil mix or did I misread something? Either way, does anyone have suggestions or should I mix the coir and peat, then do the typical 1/3, 1/3, 1/3 before addending with the supplements. I also have bone and blood meal...

I just purchased all of the ingredients to attempt ROLS. I purchased: 3.8 CF or ProMix HP Azomite Crab Meal Kelp meal Diatomaceous earth Root Naturally Sea-90 Ocean Mineral Organic Fertilizer Neem Seed meal 1 cu. ft. of growstone multiple coir bricks 15 lbs of worm casting mushroom compost...

How long did you have the phresh filter? How hard were you running it?

Nice pics and info. Keep us updated as you experiment, I'll have a few of these popped soon.

This is what I'm thinking. 315 in the middle, 12-14 LEDs around the periphery. With 14, the difficulty will be in sizing a driver adequately so it's still maxing out efficiency. Any suggestions on that? 14 CXB3070 BB bin @ 700ma would add how many useable watts/par watts? 14 CXB3590 CD bin @...

Nice! I'm going to mock up a diagram to show what i had in mind. I'll post it here, let me know what you think.

Please keep posting your grow pics. I'll be using a 315 and supplementing with COBs. I thought I was going to do all COBs but I think COB for veg and supplemented with the LEC 315 will be just the trick for a 5X5 tent.

Anyone else using LECs? Or LEC supplemented with LED? Any grow updates?

When you say caps, do you mean you just put them in soluble gelatin caps?

It's difficult to ascertain what can be taken from this and applied to marijuana. From what I gather, each plant type showed distinct developmental changes to varying the absolute and relative blue light. We can attempt to liken marijuana to one of the plants used based on phylogeny but it's...

Here is one more diagram with the mixed spectra: Green = 3500k Sky blue = 5000k Purple = 5700k Red = 4000k The only thing I don't like is the uniformity across the middle. I may be better served by replacing the two middle bulbs with 5000ks or another mix.

Hey Supra, just a friendly bump to see what's happening.
