785W LED only Grow (Real Watts)

That's right 785 real watts LED only grow. I am achieving this with 3 different 3w LED lights.

1000W LED (actually about 550w)
300W LED (180w)
100W LED (55w)

I am growing in a 4'x4' tent with a 6" exhaust fan and carbon scrubber.
Plants are DWC grown SCROG style. All plants topped once.

The strains grown are 1 Green poison, and 3 different White Widows.

They were vegged about 6 weeks. Two of the WWs took their time growing.

This is the tent and how the LEDs are set up, the 300w and 100w are raised higher now, and there hasn't been any CFLs in since flowering

this is around the day before flowering

I love it. Looks great. I am going to give scrog a try next grow but I'm also going to try six plants aeroponic style in a 4x4 with 600w hid.

This is from day 16 flower
This is when I defoliated a bit because the plant were too dense and needed to be thinned out

I just pulled out the WW#1 and WW#2 to give the other girls more space, I will reveg these two and flower them when the other two are done. I also utilized the extra space in my tent by supercropping the girls, probably the last time, and rearranging the screen to center the plants. I will get some pictures of this sometime soon. I think pulling the two smaller ones will be a good choice because I can let them get bigger and I could get some clones going from the WW#3 and green poison for the grow after that.

Tomorrow I will be changing the reservoir for week 4 flowering. I didn't get to change the reservoir for week 3 I had to refill with RO water a 2-3 gallons twice. Hopefully that didn't mess things up too bad.

These are from last night (beginning of lights on) didn't get any pictures from this morning. Might get some tonight.
First pic plant on top WW#3, bottom Green Poison, 2nd pic WW#2, 3rd WW#1

I've got to hook these girls up to their own air pump now (2 airstones will be in the WW#3 and Green Poison now which should help there also) and move them somewhere I can give them 24 hour light. You can tell the WW#1 and #2 are really bushy, I will be trimming a lot of that back before going into flower in a month-month and a half.

Oh yeah I forgot to mention, the WW#1 & WW#2 both smell like hot dogs if you rub the stems. Weirdest thing ever.

The two plants in the tent both smell different and not like hot dogs, Haha. I'm sure the final results will be different though.

These pictures are from day 22 flowering, the buds are finally starting to form, and boy are there a lot of them

These are from day 28, week 4 flowering.
The smells are starting to come in and the WW#3 smells like lemonhead candy, has kinda the smell of the blueberry gum plant i grew.

the WW#3 seed is from a WW plant I had from a grow when I stressed multiple different strains to hermy on purpose. The WW I got the seed from had less than 15 seeds and was right next to a Blueberry gum hermy which leads me to believe that the WW was pollinated by the Blueberry Gum plant

So I'd strongly suggest the genetics for the WW#3 plant to be Blueberry Gum X White Widow

I don't believe your 1400w of LED is only using 785 watts. Your plants look nice though. You think your yield will compare watt for watt with HPS? I think a HPS would be able to hit 400-500 grams with plants the size you began flowering with. We shall see! Good luck!

I'm not sure the exact wattage, but the running wattage of the LEDs I have gotten are from other people who have tested the same units. I do eventually plan on getting a Kill-a-watt in the future see the exact amount.

As for this comparing to an HPS grow, I hope weight wise it will compare, not sure if it will compare to a 400, 600, or 1000. Density and quality I hope are better. Time will tell. Thanks for stopping by man. Only 4-6 weeks left

Day 31 Flowering

I just pulled off a good amount of fan leaves that were shading potential bud sites. You can't tell from the pictures.

I plan on doing a two part harvest where I will harvest the top half, and let the bottom half/popcorn nugs fatten up for a couple more weeks under the lights. This will also help with the amount I have to trim at one time. The green poison has started making some trichomes and they smell pretty sweet, I am really excited to get this grow done.

Day 33 flowering,

The WW has started to pack on trichomes, some pretty large fan leaves have trichs all the way to the tip. Should make for some good trim.

The GP is definitely nowhere even close to the WW on trichome production, I hope it picks up soon. I think it has started to produce more.

I am thinking about turning my lights down to 11 hours on 13 off to speed things up a bit. I would then turn them down to 10/14 in 2 weeks. and maybe even drop it down to 8/16 the last week.

I haven't had any of my own weed for a while and I don't want to buy any more right now you feel.

FUTURE PLANS
I also got to get the other two WWs in there since I don't have tent for them to veg in, and the 4 clones I have taken 3 have popped roots and 1 is going to in the next day or 2. I don't have anywhere to put these clones so I have to figure something out. After the new WWs are flowering for a month I'll put in the GP clones first since they stretched more during flower, the WW#3 clones would be next and they would get a month more veg time so they can get nice and huge, expecially since this plant is super potent. I hope to get going a perpetual harvest every month or so, and that would be the line up for the next 3 grows. I am not sure if I will clone one of the other WWs, they were just too slow of growers. I might keep the GP and WW#3 clones going for a while, cloning clones.

Just a quick update here.

I trimmed off a lot of undergrowth that was very immature (only a few hairs, no bud forming) from the bottom. Kinda lollipopped it I suppose. I also trimmed off some fan leaves that were blocking light to all the buds underneath them and to get better penetration through my canopy as to decrease the amount of popcorn nugs I get. There is still a lot of undergrowth and I added a 23w CFL under the canopy, to help out.

It is pretty late in flower 3-4 weeks left I think, I decided to trim the undergrowth this late because of how immature it was, my canopy was so dense the bottom of the plant most likely wouldn't even of produced good popcorn nugs.

I'll get some pictures up soon


I wanted to add that before today the amount of "lollipopping" I did on the WW was considerably less than the GP

How's it going fellers? It is about day 42 flowering. The girls are looking great, changed the reservoir 2 days ago for week 6. There seems to be another 3 weeks still. If anyone was wondering what I did what I did with the lights here it is.

I will start from the beginning of flower,

week 1 through the end week 2: 12/12
week 3: accidentally hit the timer I guess and it was at 14 hour for 5 days (I think), everything was still flowering as you saw.
end week 3-middle week 4: 12/12
end week 4- week 5 start 11/13 (tried 11 out for 4 days)
didn't want to hurt yield so went to 13/11 yesterday because I read Urban Grower, Remo, switches to 14/10 the last 2 weeks of flower for increased yield and potency.

I know this light schedule has been pretty messed up, I don't need anyone to tell me that. The next grow will solely be 12/12 because I will be starting a 1 month-1.5 month perpetual harvest with only 2 plants in the 4'x4' tent (4 dwc was way too crowded for changing reservoirs under the scrog, and I like that I will use less of the nutrients, saving me some $$$

I think the girls look fantastic, a bit of nutrient burn but not bad(I decreased ppm this reservoir change). I hope to keep the nute burn out of my next grow since I already know what these girls can handle, and what the will need.

The green poison should have a killer yield by the looks of it, there are about 11 huge 10" colas that should swell up soon.

Here are the day 42 flowering photos

If anyone was wondering what my electricity bill is..... it is....... $45, this is the total bill. I also have a saltwater fish tank which uses probably around 200w 12 hours a day and 100w of that is 24 hour (totally guessing, need a kill a watt). So if I had to guess my set ups cost each month, I would say... around $15-25
a month... LEDs kick ass!

I'm doing green poison outdoor this year along with some kalishnakov, blue widow, ak, chem dawn, and a few cheese strains.

The Golden State man, I'm paying about $0.13-0.14 a kwh.

I noticed the girls are just starting to swell up, I'm looking forward to them both, the white widow is super frosty, and the trichomes are really long, the green poison is just starting to pump out trichs, these plants are going to be so thick with bud by the time it is finished.

I grew a blue widow about a year ago, did get as much love and care as these girls, I was gone for 3 weeks of the flower, it still turned out pretty well I think.

Nice tier 1 billing. I'm into tier 3 and paying around 6-7 a month with all households stuff.. 2 fridges air compressor 3.6k in HID I'm not energy efficient by any means so I could definitely bring it down a bit
