Diy Grow box or Tent? Advise please

stonetech got you hyped that was a good grow. GL

The main problem with tents is being light-tight. Not so much of a problem in a loft grow. However, keeping temps stable is....

I just thought that some industrial grade velcro would do the trick! gonna try and find some tomorrow

Yeah stonetech and a guy called nets 2-3 on the uk420 site have similar grows and were definitely the spark in this idea!

Velcro on white visqueen is the way to go. My friend made a brilliant wooden framed grow room in a garage and he used velcro on this plastic to open and close.

I don't do vertical so good luck (I prefer horizontal!!)

The velcro is going to be for the hardboard to the frame, although i can see the bonus of velcro on the plastic, i like the idea of re usability.

hook and loop fastener is the real name for velcro it will take a while of searching but there is some cheaper versions out there for way better prices.

My friend used the corner walls, painted them white and put a flooring down.The frame was a good 2.5 metres across and 1 metre deep. It took up the height completely. He velco'd it all across the front for easy access. His lower intake was a metal vent, (like the ones in kitchens) placed near the door to outside. He was pulling out air at the light level to reduce heat. This created a vacuum of fresh air being pulled in lower and hot air exits higher up. He's very good at DIY and helped me board up my windows.

here is the intake its a 125mm hole the same as the fan, so long as i get negative pressure ill be happy. The fan can really shift some air so i know there is plenty being refreshed.



I really want to do a vertical grow in there.
As the heat goes, it is hot in there at the moment so may consider a cool tube or another fan blowing on it to move the air inside more. I am not bothered about winter time as i know this will not be an issue.

Do you reckon the DWC will be overkill? I want big plants, i want to use up all of the space. Hopefully with proper training this can be done.

you moved the exhaust to hang from the top and pull the air close to the bulb?

DWC is gonna fill that up your best be to fit it all in there and do awesome would be an indica dominant strain some sativa(60/40 70/30), 12/12 from the start and line the walls with chicken fence and train them to it the whole time.

Yep got the wire. But can decide what to attach the mesh to.

If i attach it to the wall then i think it maybe hard to tend to the plants. I was thinking about somehow attaching the mesh to the pots so that i can take them out of the box and tend to them.

polyarcturus, are you saying not to DWC?

Got white widow and super cheese to grow in there, 2 of each

polyarcturus and no, that is the intake, the exhaust is still at the top, although i have made a design blunder.

i thought that the 5 inch intake would be enough to match the 5 inch fan that i have (passive intake), apparently i need to increase the size by 3, so i am going to put another 2 5 inch intakes at the bottom.

yes correct intake must be larger than exhaust. as far as passive goes.

with those 2 strains that would be great for DWC and in that setup and vert wanting a huge yield hell yeah i would do DWC! now i could see doing soil if you where trying to grow a few plants but this isnt the case hydro is much easier when its a diect path to the end unlike perpetual flood and drains and aeroponic systems, soil simplifies that and coco lets you bend the rules of soil for the most part.

dont attach it to the pots then you will be limiting your space get 4 more supports to got to the ceiling from the floor and mount them a few inches out from the wall and attach the fencing to that with a staple gun

i would use 2 metal angles on the support one at bottom on at top so they would swivel and i could run fencing in a U shape. if i where you i might even set i up so the fence was on the inside of the pots. usin 6 supports and making a+ shape minus on prong because thats where you enter.

Yeah gonna put the netting on the wall side, don't want the plants to go too near the light, its well to hot and don't want em to get burnt. All i need to do is to figure out the door, i am sure i will be able to do this when i get round to putting up the netting.

So, I still need to get me some air pumps for the DWC.

Although when i was searching round ze internet last night, i came across a thing called no mercy growing, basically a setup where the light cycle is always at 12/12, an interesting read and idea. In my space it recommends 26 plants, potentially 26 oz per harvest, problem is 26 plants round my neck of the woods will land you in some serious trouble, no more than 9. and i am only growing for myself only however, i like to experiment a lot so must not let my curiosity get the better of me.

I may nab a cutting off one of my plants and see what happens when put into 12/12 just as a little experiment. I am very intrigued.

lcone will grow for 2 weeks like veg then start to flower stetch an fill out according to pot size for the most part, there are limits as far as size can go but a 12/12 clone can get pretty big in a 3gal pot of soil 5 gal dwc would have it nice and big too. honestly i would just do 4 big buckets like you had or 8 2 gal buckets, 12/12 from seed. the 8 2 gals canopy would be easier to manage too. i would go with 2 strong air pumps(metal 40$) with a 8 way manifold and just the cheapest air stone, 4" long airstone, you can find. 12/12 from seed takes about 90 days. roughly, 12/12 from clone can go from 50-80 days of course depending on what you growing and pure sativas can go much longer. hmmm 26oz of a 600 not likely. lol gram per wat outs you at about 20 oz but that is unlikely since you still have to dial in everything on your setup 10-15 oz is a more reasonable number to try and reach. also another note with 2 gals you could put the fencing on the inside(toward the light) of the pots since they are smaller.

Actually, gonna scrap the idea of the 12/12 and just hit it with the 4 DWC buckets, although will probably do a cheeky clone and see what happens.

Cheers for the links! Gonna use velcro for the sealing, no need for hinges as the whole side comes off but nice idea about the lock, not sure ill need it though, as only friends stay over on the odd occasion and ill just make up excuse that i am doing an experiment or growing a special banana tree they will understand ................ i hope

added another 2 5 inch holes for the flex ducts today and wow what a differencebefore temps reached 42c now sitting around 28c, so, amazing what an extra 10 inches can do. I may even put another hole in the box to make life a bit easier for the fan...... time will tell. 2 super cheese and 2 white widow will be started in 7 days wooooooo hoooooooo

a vertical cooltube in that box would just make it perfect

very nice diy job! actually think i may build something very similar to this, definitely more rewarding than buying a tent and much more solid.
