Im working on a grow inspired by yours, its going to be a smaller number of plants flowering but will be a perpetual micro grow with cfls. At the moment Im working on my momma box its about 2.3 sq ft.

can you give us the dimensions of your flower/clone box?

~~It's a old kitchen cab. the clone shelf is 23"x12"x14"~~
~~Flowering if I remember right is 24" x 14" x 28"~~

Thanks in advanced.

Dr. BudGreenGenes...You say that your cab has "45.13 lumens per square inch." There are 144 square inches in 1 square foot. 45.13*144=6498.72 lumens per square foot.

Let's now look at your cab. You say that it is 24'' x 14'' x 28''. This is the standard way of saying 24 inches by 14 inches by 28 inches.

The surface area of a rectangular prism can be determined by the formula; Surface Area= 2*length*width + 2*length*height+ 2*height*width.

Given your measurement let's allow; length=24; width=14 ; and height=28

The Surface Area=(2*24*14)+(2*24*28)+(2*14*28)=2800 square inches or 19.45 square feet.

Based on your calculations you claim to have 45.13 lumens per square inch.
Your cab (dimensions provided by you) has a total of 2800 square inches.
The total lumens within your cab can be determined by multiplying total square inches by lumens per square inch.
Total lumens= 2800*45.13=126324 Lumens.

If I divide 126324 lumens by 19.45 square feet; 126324/19.45= approximately 6500 lumens per square foot
as determined earlier.

Now you seem to imply that you have only 5 lights in your bud box pg.3 post 36

Dr. BG, you say 4 across the back and 1 on the side (lights) ?? The pic looks like 3 in back and 1 on the side (?).
That pic is of the "Clone Shelf"...it only has 4 lights 2-13 watt WW and 2 -15 watt Florex

What "flavor" cfl's are those (color temp ?, warm ?, daylite ? etc.).

They are Warm White 42 Watt


And....could you tell us a bit about your cloning methods ?


Take a 1"-1.5" cutting....cut at an angle....dip it in Rooting powder....put it in a 3oz cup of perlite...NO MISTING EVER....Place in 100% Humidity enviroment..air blown in once per day until ya' see "Yellowing"indicating that they have rooted and then start hardning them off a lil' at a time til the lid is off...water with 1/2 strength ferts(everyday)....as soon as I see any growth...into a bottle they go and into the box



Below are some pic of the Bud Box...back when I built it and could get far enuff away to get it all in a pic

This is a good example of the different Spectrums of CFL's....First pic is Warm White...second is Cool White and then "Full Spectrum" mix

Thanks.
Be Well...Be Safe.

and pg. 7 post 95

~~~Yup' they sit on some 4" pots that are about 5 Inches tall for about 7-10 days when they first go in
If the 150 has a remote ballast I think it will be cooler....cuz my 42's in this small space is HOT....the fan is all that keeps it cool enuff to grow~~~

responding to krly.

If I divide total lumens by the number of lights then I will get the average number of lumens per bulb. Again, total lumens=126324 and you have five bulbs; thus, 126324 lumens /5 bulbs= 25264.8 lumens per bulb

I don't know how many lumens the ES42's have but I'm sure it is less than 25264.8 lumens...
pg 24 post 360

The Lights are Self-Ballasted CFL's......
Model ES42 (from HomeDepot)
Sockets are also for sale there...
Wiring is SIMPLE they all have two screws....1 silver and 1 brass.....lamp cord has two wires run ...........one continuous wire from the last socket to the first.....connecting all the brass screws with one wire and connecting all the silver ones with the other........add a plug to the end and its done

But wait.....
If we go back to early days on pg.1 post 1

I'm new to IC and was wondering if anyone does a SOG style grow with CFL's on a Micro-level?

The reason I ask is Bcuz I do it's 210 watts of CFL's over 27 clones in 2 sq. ft.

The girlz grow in a 16 oz soda bottle filled with my own soil mix...they finish in 9 weeks and Avg. 21 Grams dried per plant and I harvest 3 a week...SOG Perpetual Harvest this is a pic of one of my girlz

we see that you state you have 2 square feet for a bud box.

Again, there are 144 square inches in 1 square foot. Therefore, 144*2= 288 square inches. 288*45.13 lumens per square inch yields 12997.44 lumens.
12997.44/ 5 bulbs= 2600 lumens; a standard amount for a bulb of that size. 12977.44 total lumens/ 2 square feet = 6488.72 lumens per square foot.

What does all this mean?????
If his cab flowering cab is 24" x 14" x 28" all those haters can keep on hatin'

If his cab is 2 square feet he's one of the best micro-growers ever.

Im inclined based on pics to believe flowering cab is 2 square feet not 19.45.
Anyway, I'm just putting it out there so you can fix it.

So Dr.BudGreenGenes is your cab 24" x 14" x 28" or 2 square feet?
Peace

Brother, you are confusing yourself with your own numbers.

Its obvious that 24" (2ft) x 14" (1ft 2") is just a bit more than 2 sq ft.

24"x14"=336 sq inchs /144 sq in per sq ft=2,33 sq ft.

45,13 lm/sq inch * 336 sq inches=15163 lm. He has 5 42w CFLs, so each CFL emits 15163/5= 3032 lm.

Roughly 3000lm for each 45w CFL, around the typical 65 lm/w of CFLs.

And that isnt low light levels, i use still less (19200 lm in 5 sq ft).

knna are correct if Dr.BudGreenGenes calculated 45.13 lm/in using cab floor only. I suspect this is what he has done. I am truly sorry if have bothered anyone; especially Dr.BudGreenGenes.
I have started another thread for lumen calculation in order to promote further discussion elsewhere.

the cab floor is what is generally referenced in the watts per square foot equation, not total surface area

 

[Guest]

I have the lumens at 2800 for the HD 42watt X 5 = 14000 lumens

 

[DrBudGreengenes]

I have several Brand new ones in front of me....n:Vision "Soft White" ES42 42 watt =150 watt 2600 Lumens

 

[DrBudGreengenes]

K..........."Tale of the Tape"
Flowering box is ....
24" Tall
24" Wide
14" Deep
24" x 14" = 336 sq. inches(Surface area of Floor/Growing area)
336 / 144= 2.33 sq. ft
ES42-42 watt CFL= 2600 Lumens
5 x 2600 = 13,000 Lumens total in box
13,000L /2.33sq.ft. = 5579.3 Lumens per sq.ft.
5579.3 / 144 = 38.74 Lumen per sq. Inch
Or 210 watts / 2.33 = 90.1 watts pre sq. ft

thanks for the answer Dr. Very informative, and some useful advice on how I might wanna set it up to be accommodating for different flowering times, especially these Haze crosses.....if its a long one.....I'll def keep it around. Everyone who says they went for time over quality lives to regret it, not just you man, so I'm gonna listen to other people for a change and try and learn from previously documented mistakes.

So that's pretty much the equivalent of a 600W lamp for a 4X4 area which is what I'm using. I'm moving towards a more perpetual setup right now as I have 5 Satori plants 3 weeks in and I'll be harvesting the rest of my plants within the next 10 days or so. As I'll eventually also be putting in some unsexed plants I'll get spaces when I pull males that will get filled with sexed plants so eventually I'll have plants at different ages in there. I don't think I want a harvest every week because it's gonna be a mess to keep track of - but perhaps every 2-3 weeks will be nice. Obviously I won't realize huge yields since I'll probably always be doing multistrain grows but I don't think it's much of a problem having plants of different ages, sizes, flowertime and stretches since I can rotate pots and move them around to create an arena effect. Perhaps if I can up my clone productivity I'll try putting 4 plants per 6.5L pot.

You have been a great inspiration for my own grow and I'll definitely try and see if utilizing some of your methods will help my yield. One thing is for sure though - I don't know if it has been touched here, but a staggered harvest is a good way to gain experience fast because if you have a problem with the strain and think you might have a solution you can apply it immediately to the next overlapping generation and see the results.

Also I won't mind harvesting, trimming, repotting etc a smaller amount of plants every couple of weeks instead of being forced to trim for many hours every 2 months.

Hey DrBudGreengenes!!!

Im impressed!!Could you please describe the exhaust for me..or if you have already done that just tell me on wich page the details are.

Very inspiring work,also what strains do you like the most for your lttle cab or wich ones were the best for such a setup to date?

Thanks alot in Advance!!!

Best Regards....Goldenseed

 

[Haggis123]

I think GVSB got a bit carried away with himself there...

Anyway's, Doc keep up the good work...you are a true inspiration to quite a lot of peep's here with your thread....me for one.
I have been considering going micro for a long time, gave up growing in my converted wardrobe a long time ago....needed the space for a growing family...lol.
Was looking at a kitchen cab simillar to yours, but doing scrog....after seeing what your doing...switched me onto the micro Sog style.
Will try and do a tutorial through the build of the cab, when I can get my butt into gear...just to help out any others contemplating this style.

All the best...

Wow, nice work Dr.Bud. That is Jedi type shit.

If you did have an hps what size would it be and what would you do with it?

This perpetual idea has promise. Do you try to take advantage of side lighting with the height differences?

Cloning, seems as though the bacteria/fungus in soil would be great for establing healthy clones.

any thoughts would be appreciated.

Doc after reading through this thread again i see that you have used C99 in you SOG. Did it perform well for you and if you can remember what was the average yield per plant.

the C99 was under a 430 and did about 15-17 grams each[

[Guest]

Sweet buds DrBudGreengenes you have inspired me to go perpetual sog and i have a ? for u,how do u figure out how many clones fit in a curtin space?cause i'm thinking about runing 9 clones every 2 weeks for a 9 week strain and almost 4got my space is L25xW18

 

[ripOG]

Hey Dr,

I'm setting up a PC as a flowering cab and I'm going to run a SOG under about 200 watts of CFL's. I'll have about 20" of space underneath the lights. What size soda bottles would you recommend for pots? The dimensions are 23.5” H, 10.5” W, 24.72” L.

I think I'm going to rig up a small board platform on 4 adjustable light hangers for holding the pots. This way I can keep the girls close to the lights throughout the grow like you suggest... I'll just lower the board as they grow. Thanks, this thread has been a real inspiration to me.

 

[ripOG]

Thanks for the pics, your girls look so cozy in there! Do you need to do any trimming or do they just figure out how to share space on their own?

 

[sogdog]

Hi Dr bud! Long time reader,first post.I plan on emulating your system as closely as possible.I was going to use a rubbermaid setup that is already to go.It was built originally to be scrogged until I read your thread.Its painted with multiple coats of black,then white plastic paint.I even have cut the plexi glass to fit tub to vent lights seperately.It is designed from the "redgreenery"thread.I was going to use 23 watt cfls as they are cheaper to buy in multi packs then the 42 watt ones.My question is,will the 42 watters penetrate deeper than the 23 watters?I was going to double up the smaller cfl's.If the 42 watters penetrate deeper than I'll go that way.What is your opinion on the flowering lights? I plan on using the fluorex and such in the mom/clone area, as mentioned earlier in this brilliant thread.Thank you for your time sir!

Heeyyy DrBudGreengenes!
Great pics with great colors!! Ya lady´s looks hot bro!!

Nice i may be able to yield a little more than i expected. Another question i have is, have you always used simple nutes like stuff you could go pick up from say wal-mart or home depot etc. And i read in this thread that you contribute alot of your awesome yields to our micro friends in the soil. Have you ever used any products that claim to enhance or add microorganisms to the soil?

I'm assuming that since your so far away from civilization right now that you are not using chlorinated tap water but when you were on a bigger scale im sure you did. I've read that tap water kills both good and bad bacteria, so do you think it'd be better if i collected rain water or get one of those Fish products that remove chlorine and chloramines from the water?

By the way those pics of the ladiez RawK , are those pics of the Chesaw?
