OK so I'd Like to give your nutrient setup a try. So could you point me in the right direction?

So far I have picked up you use Iguana Base Nutes.

IS that all I need as far a base nutirents?

Also I read in your posts you use Big Bud. When do you Add this, and how much do you think it helps?

Everything looking ok to order???

 

[HydroGrowLED]

Actually, we use the bloom nutes for veg as well. Seems to make them stack up a bit nicer in prep for bloom lol! We mix in some other stuff like cal/mag in veg, but not a whole lot. For bloom I just use the Iguana and Big Bud. I've used Voodoo Juice as well, I just need to order it again... Come to think of it, I need to order Iguana again too. I use the stuff as per the bottle: 1tbsp Iguana per gallon, 1.5tsp big bud powder per 5 gal.

those are some crazy buds... any chance you could get a pic with the lights out (maybe turn the flash on) to get a more normal color?

i think when i need to replace my lights im going to get some of your units. in the long run it seems more than worth the higher initial cost.

For next week's photos, I'll go ahead and do some lights off, some lights on to give you the full picture of what these girls look like. In person you can see them perfectly, but the camera sees more of the other spectra than we do. I'm leaving for CA in a few hours, and the lights are still on, otherwise I'd snap a few pics now and edit them on the plane.

Question 1: I'll only talk about tray 1, as tray 2 underwent a bit of stress. My plants in tray one are all varied in strain (AK47, ICE, Afghani x Brazilian Skunk, etc..), and each will yield a different amount. No plant will yield less than 4 ounces. My stronger yielders will pull a half pound each, although they currently look like they may do a little more. All in all, I expect a 6 ounce per plant average on 8 plants, under 756W (1 bank) of LED's, for a total of 3 lbs. The canopy size is 3' x 5'.

Question 2: The 318W puts out a LOT more PAR watts in a 4' x 2' space than your 1000W will. It is about equal to a 1000W HID in PAR watts, except for the fact that the intensity won't start dropping off on you after month 1. For a good grower, I expect they could yield 1.5lbs with a single 318W, which is also pretty comparable to what most people do with a 1kW HID. Some can produce higher, but they'd likely also be able to yield more with our lights than the next guy. If you want the best 1000W replacement, use 3 of our 126W. If you want MAX growth in any area, then the 318W will do it. My guess is that when you stack multiple 318W's together like my 126's, you'll end up with higher than 1.5 lbs per light in the end.



Not currently, but it's on my list of things to get from the store (they were out of stock this week). My humidity is at a constant 75-80 percent right now, which isn't horrible, but any higher can cause trouble. Ideally, I'd like it around 60-65%. Humidity does make quite a difference on yield, most people don't realize that

REALLY!?!?!
The variety I was using was Pot O'Gold(Flying Dutchman seeds), BUT with 4k watts of crop the lowest I could bring the humidity down using 2 dehumidifiers was about 55% and still the botrytis required a consistent monitoring and beat down.


I just put an order in for Wonder Woman & Master Kush seeds. Also have a vintage stash from KC Brains. I am not familiar with the resistance of any of these though.

A more resistant strain with that yields as big(or bigger) would be of great interest. (Similar low odor would be nice too)

WHAT ARE YOUR BEST YIELD STRAINS???

(For anyone who is dealing with botrytis/grey mold/bud rot: you know how persistent the problem can be. Cleanliness and Trichoderma harzianum mixed with Einstein(cold pressed neem oil) and water worked consistently well for me..... Potassium as well as sodium Bicarbonate have also been reported to be effective.

BTW Cammie
Thanks for the explanation on the 318/1ooowatt comparison.

If your growing in a DWC or bubble bucket type system I would think humidity would be easier to control using LED's because the water in your reservoir would not evaporate as fast.

I do believe you are correct Warbux. LEDs would probably be a giant plus as I WAS using a home made DWC system just prior to switching to the Ebb & Grow in an attempt to control the humidity more effectively. I was adding water way more than I wanted to and I knew much of it was going to the air.

 

[scumbragger]

I've "flushed" my plants in the past, and done the whole "run water your last week" think, and it never made the slightest difference on the taste of my bud. Might be different for other people out there, but that's my experience.

Your using organic nutes which don't need to be flushed...way different!

The humidity in my garden arises more from the fact that I use chilled water, in a warm environment. With my room at 85-90 degrees, and my res at about 70, it causes condensation to form on the outside of my trays. While the plants don't use the water as fast, my humidity seems to arise from the temp variance. Anyhow, just thought I'd point out one of my observations.

OH and CANNA - my best yielding strain currently is Strawberry Cough X White Rhino. Hopefully my new strains will be able to match her with better quality.

Big Bud isn't organic lol. Even when I was running Humboldt Nutrients Master A & B, or Advanced Sensi A & B, I didn't flush. Both were synthetic nutrients, as was Connoisseur. The only one that ever had an effect on the taste though, was Connoisseur, which seemed to intensify the flavor almost to a point of being too spicy. I only used Connoisseur about 3 cycles, before I proved to myself that the yields had actually fallen a bit, even though quality increased over the Sensi. That's when I found Iguana

MY room never goes above low 80's but we need that to run the O2.O2 systems need to be abit hotter.Rez stays a constant mid to low 70's.going for the chiller myself in jan.see if i can push another 5 to 10% yield.position of your rez has alot to do with your water temp and condensation.If i move mine 12 inches in the direction of the light ill get a 10 degree swing.If you are in the high 80's to 90's with out O2 you killing yourself.You need to vent that heat, the plants will do much better less mold and mildew.all that sweating on your trays will start to get mold on the buds.I would be shooting for 79 without O2 maybe save yourself some problems in the future.Just my 2 cents

Big Bud may not be organic but it sure smells organic. GOD that stuff reeks. It smells like 3 day old baby throw up

You need your room to be in the low 80's to run oxygen? You've confused me, mind helping me out a little lol?

My res is located directly beneath both of my trays, meaning that it is blocked from the LED lights above them (which don't heat it up anyhow lol). So in my garden, position doesn't have a whole lot to do with it, but I can see how it would with HID's. I don't see how the position in my garden would affect the condensation either, so if you want to elaborate, I'm all ears The condensation on my trays forms because the air outside of them is 85-90 degrees, and the water in them is 67-70.

I disagree with you on heat though. My plants LOVE 90 degrees. 85 is ok, but 90 is where they thrive. Even when I had HID's I ran my room at 90 degrees with CO2. Plants thrive in heat, they simply have a tolerance point. With HID, that tolerance point is met earlier due to the heat being created via IR from the bulb (and the operating temp of the bulb). With LED, I haven't yet run my plants too hot, and I tested 4 plants up to 98 degrees for several weeks without CO2... What I need is a de-humidifier is all. Get the humidity down to about 65%, and keep everything else the same for me.

my led plants lived in 95-100F* their whole life and lived i wasnt using co2 either, but did get mites and it was game over after that. the whole time i thought is was my strain (sativa) but i guess all led plants can deal with extram heat. makes sense that why plants out doors live threw alot of heat in the sun.

That's true, I mean I've watched that stupid CNBC special on "Marijuana Inc" plenty of times now (as well as other such shows on the topic), and they are always talking about the forests of weed growing in the national parks in CA. Southern CA gets over 100 in the summer time, and plants do fine outdoors. Then again, I think my face gets hotter 2' away from a 1000W HID than it does sitting outside in the sun...

Cammie,

The 12x24 board you use for the 126w units has a lip or margin around it. It appears to be ~2.5" or so all around for the casing. Is that about right?

And, is that about the same margin for your 63W unit casing?

Can't really tell from the pics...

Thanks,

-TL

 

[HydroGrowLED]

If I remember correctly (as I'm not at home and cannot measure one of my units), the casing measures 19" x 12.5", while the LED area measures approximately 8.5" x 16"...

The 63W is around 12" x 4.5" light area, with a 16" x 8.5" casing (again just based on memory).

wow. thats one monster. i was thinking it must suck to raise all of those lights when the plants grow. looks like you would need a lader.lol.

good job hope my plants look like that.
