Red_Greenery's Handyman's DIY Grow Tub

[Flutch]

one more quick q
where is the best place to find the rubber maid tubs?
and is the 25 gal or 31 gal what im lookin for?

I would check Wallmart, or any other big chain stores like that. That size is fine i believe mine is about 19 gal, but will go with a bigger one soon. I will be using this box for clones and stuff like that. But right now money problems so have to do with this box.

i got all my supplies from either walmart (which has the rbbermaids your looking for) or home depot...except the fans, those came from rip off radio shack lol

Quick question should I shorten the air return hose? Is this blocking air flow because of the U shape in the Return hose?

Yes, you should. More bends = less airflow.

 

[Guest]

if your temps are ok id leave it...besides if the fan is strong enough itll pull it threw

 

[Brad Lee]

red,

job well done.

i gotta have one.

peace

Wow - I'm pretty impressed with the gang here at the Lodge. This place is hopping!!!

Sorry guys that I haven't been around much. I picked up a bad cold after playing golf in the rain and missed a week at work and then it turned into bronchitis and missed another week. I was living in the Lodge and wore it out while I was sick.

I quit smoking herb this summer and have been vaping and making edibles all fall so the herb hasn't been a factor with the bronchitis. Anyway I've been in the gym just about every night doing aerobics and I started taking yoga class too. Gotta get ready for the ski season and I'm back on track with my overall fitness program.

I've gotta spend some more time reading all the posts in detail but not tonight.

Take care all!

I am about to take the challenge myself. I have previous experience indoors with small cfl veg box's and with using a 150 and 400 hps lights in a closet.
I plan to start with a veg/drying box like Red's shown earlier then putting together a Red style tub grow using the regular stacked tubs uber stealth method shown a few times in this thread and not the upside down top tub style. I need extra stealth like some of the others had mentioned. 2 questions..

1. what do you use to cover the air intakes besides a light trap? I have cats :kitty: and i plan to put the system under the stairs where it is dusty and dirty and potential for cats hair is high. Would womans stockings work? or too airflow restrictive?

2. Has anyone lined their tubs with aluminum foil ( to block light from escaping) prior to putting up the emergency blanket (to reflect light)? Seems to me this would be a simple solution I intend to test the theory

I look forward to your thoughts and input

Hey - welcome buzzer!

Interesting idea, using foil under the mylar - the only thing that I can think may be a problem would be reflecting heat back into the tub. Let's see, when you bake a potato, you put the shiny side in, to make it hot... I'd put the shiny side towards the tub wall, so's not to bounce heat back into the unit. Hey, might not even be a problem.

Alot of folks here are starting to use Reflectix instead of mylar - thicker, probably light-tight... get it @ lowes in the insulation department.

Good luck - you've got a whole lot of great guidance, here in the lodge!!

 

[bounty29]

I'm currently setting up a garbage can grow, I just quadruple layered an emergency blanket, I'm pretty sure it will be light tight but I haven't tested it yet. We'll see in a few days.

 

[Mr_Micro]

Is that the right food? I think I believe Mr_Mirco used the same stuff!

Woah! LOL I was freaking when I saw that pic! All of it is the exact same stuff I use right down to the brand of hydrotron! Do your DWC/SWC grow With those 98% organic nutes and natural PH adjusters and you'll be rewarded greatly!

Sorry to hear that you gave up on your PC Case grow box though. It was looking so good! What went wrong?

But in any case, I'm just glad to see you got a good grow going man! These Red style rubbermaid grows really seem to give some great results and at little expense too! Cheap, easy, and effecient. Heck, I might have done one myself but I really needed a higher level of stealth than a rubbermaid tub grow could provide.

Maybe one day if I need something a touch larger than my PC cases I might check out those posts a few pages back from the guy who did a Rubbermaid grow but had it look like just 3 tubs stacked normally on top of each other. All the venting and suspcious stuff was in the back so from the front and sides they just looked like normal rubbermaids. But hey, I'm happy with my PC cases right now but you never know what the future may hold.

I did actually turn to this thread for inspiration the other night when I started building a drying box though. I used Red's design with a few minor modifications and I now have a simple and fairly stealthy drying chamber for my soon to be harvested buds.

Thanks for all the inspiration Red! I think you've inspired almost everyone in the Micro section in one way or another

 

[SuperZero]

Hey Red, nice to see you back, been wondering what's been up.

 

[Flutch]

Doing a practice run.

Doing a practice run.

Hello!

Just finished the box, and doing a temp check to see how things are

Here is my first hour check with temps in these ranges, all three temps are from inside the box. My only thing that i might have problem with is that i only have 6 23w in there my temps are going to be much higher with 6 42 in there during flowering.



Will update every hour to show you my progress.

Thanks again for everything Flutch!

Temp Question

Temp Question

Ok so here is my deal, from the picture above my temps really have not changed from one hour ago, it has been two hours and one says 75.0, 77.0 and i moved the third one outside the box and it says 64.9!!!!

That is almost 13 degrees difference!!! Should I be worried about that, the reason i ask all you guys say that the difference in your guys boxes is like 1 or maybe 5 degrees. Is my filter not working? Or is everything fine. I don't want to start growing and it starting to smell like weed! I can't have that at all!




The box is under my house, where it is pretty cool.

thanks for all your guys input!

 

[Budless]

Maybe it has something to do with the insulation material you are using. I mean it is insulation to keep your car cool during the hot sunny day so it's probably keeping the heat in along with the light. Just a thought though. Then again CFL's don't produce much heat in the form of light, rather in the ballast.

 

[ABlueDuck]

It looks like youve got alot of slack in that dryver ducting showing in the picture. That stuff creates more drag than you think, so the less distance you have to push air through it the better. maybe even crinkling it up together when your not taking the top off or whatever would be a way to reduce some of it. Or you could do somethin like mine and make a way to easy on/off attach it to the rest of the filter. Just an idea.

I dont konw what other smell problems people have with these type of boxes, i havent really noticed any an i built one of the most bootleg/obvious design flaw filters ive seen, but it still does the job. If you ever smoke in your house, its goin to smell alot more from that then it will from the box, but then again mine only has 2 little plants in it an it depends on the strain.

Fletch- are your intake holes twice the area of exit? Looks like in your picture all inlets & outs are the same diameter.
I remember back several pages, a math lesson 4" diameter=12.56 sq inches 4xPi(3.14)
I cut my inlets to 5" x 5"=25 sq inches



Peace

Well I have a 4" fan on my scrubber, and I have two 4" air intake. I thought that this should be fine right? My fan has been on now for about 6 hours I think and my temps are around 76 and 79 on my two temp readers.

Hey Guys,

If you're interested, check out this site from the EPA. This is an excellent how to guide to set up any ventilation system, provided you can work out the math.
http://www.epa.gov/eogapti1/module5/hoods/performance/performance.htm#entryloss
Gotta love it when the goverment shows you how to improve your grow box design!!!


Basically Flow = K * sqrt(pressure) * Area where K is a constant specific to your system.

If you have a ventilation problem, there are two ways to fix it.

1. Increase the pressure produced by the fan by four times and the flow will increase by two. Bigger fans only produce half the expected results.

2. Increase the area of an intake, a scrubber or some restriction and you will increase the flow proportiononally, meaning double the area, double the flow.

Bottom line, if you have a blockage caused by restricted intakes or a scrubber, doubling the intake size or doubling the scrubber area will double the air flow.


Incidentally, by doubling the intake size, the pressure loss is reduced by 80%.

Day 25 from germination... PROGRESS!!?!

Day 25 from germination... PROGRESS!!?!

Well, my girls are taking-off, I wanted to share tonights pics w/ Y-all:




These little ones have been thru a whole lot - but I believe they're starting to pull-through, and get healthy. I have concern for the Northern Light, on the right: it's looking a bit brownish, and is considerably smaller then the White Widow - can anyone tell me if this is need for concern? I'm amazed at the difference between strains - the leaves on the White Widow are so much darker, and considerable wider then the Northern Light - is this normal, for these strains?

Stats: WW:
Height: 2-3/4" Width: 4-3/8"

Stats: NL:
Height: 2" Width: 3-1/2"

Average temperature in my growtub is around 78F

Man - I feel like the father of a newborn again!! Once again - any advice is most certainly welcome!!
