ok so im probably getting in over my head but i dont care. im getting ready to start my very first (of many) grow! i have a 250 watt metal halide hps light, foxfarm ocean forest soil (mixed with perlite for drainage) w foxfarm nutrients. i also bought some happyfrog bat shit and some neptunes fish and seaweed fertilizer. my grow space is 2'x 2'x 8'. im waiting for my seeds that i purchased from nirvana seeds. i got 5 feminized blackjack seeds. my questions are...how many plants can i grow with this space? is this a decent setup for this bud? help me out people!

are u using a fan or humidifier? or both.
Stevie: This is not as efficient as an "end for end / intake & exhaust" 250W Housing. But for your situation it would work (Check out pic). Basically you install an inline fan (100 - 165CFM) should do the trick. However this fan will be reversed. In other words it will suck the hot air from out of the light housing and you'll want to run a foot or two of ducting to blast it through the top of the cabinet. Remember that "hot air rises". And there will be a lot of heat coming off that deflector that wants to go no where but straight up. You'll also want to do a passive intake on the bottom of your cab, and also setup a carbon filter. Whether you chose to do a separate filter / fan combo or combine it with your light / vent / fan setup that is your call. If you do however do an "all in one" you may want to think about one of the more high end tornado fans. The inline's are about $35 - $45 bucks. The high end ones (They look like a turbo charger and use impellers) start at around $100.00. But compared to what (2) inline fans will cost you, plus less materials inside your cab it all evens out.

Here is the pic of the light I am talking about:

This is pretty shade tree (used pain program). But you'll get the jist of my idea on how I'd do the cooling. With this setup it'll take a bit of work, but you won't have to worry about stinking up your basement / closet or where ever your cab is located. The black line in the upper end of the cabinet between the light and the filter is a shelf. You can use that to hang the light, and will want to drill a number of good holes for ventilation. And of course a 6" hole to run the inline fan from the light through.

How were you planning to grow? Bushes, SCROG mini-SOG or what? You have 8 feet of height and a light with about 15 inches of penetration and width-wise one half decent sized bush would be like 4 pounds of baloney in a 2 pound skin in there.

So what's your plan?

Mr. Ganja: Check out my post and both pics. The bottom pic is a shade tree setup I think might work for him. Or in your opinion would he just be better off with a 150W HPS?

Stevie: Here is one last idea (If you want to save a shit load of time and effort).

Ditch your 2 x 2 cabinet and for about $100 - $120 you can get a grow tent off eBay. They already come with good dimensions, have built in vent holes and velcro passive intakes with light blocking material. They're as turn key as you can get. Just a thought in case you're not a handy man!

The 250-watt will only have about 15 inches of light penetration, a 150-watt would have less. That's why I asked him if he planned on going SCROG or min-SOG (as in a small number of plants . maybe that should be called POD, pond of green instead of sea of green) and one half decent sized around/across plant would fill a 2' x 2' area.

The best thing he has going for him is the height and with a light with only 15 inches of penetration he can't use the height. He needs to grow low and grow small or else he needs to go up on wattage to something like a 400 with a sealed air cooled hood or a CoolTube so he can use the height he has to work with.

Put a grow tent in there ... and if you don't want to spend the money on one make one using PCV. Thick/heavy PCV strong enough to support lighting and any fans that might be needed, with all the fittings and connections, corners, 'Y's' 'T's' etc. that are available at any Lowes or Home Depot it makes one easy to assemble, just need a tape measure, a hack saw and the 'goo' to weld it with and use a double layer of poly (some call it panda poly) to close it in with .. it doubles as your sides, top and bottom and your reflective material.

Section it off into a lower veg/clone chamber (using cfls or a 2ft T5 fixture) and a top flowering chamber (with 250w hps). Maybe 2.5 feet of the total height for the veg area, and the remaining 5.5 feet for flowering. That should still leave you room for a carbon scrubber and exhaust fan, I think.

Then...do a scrog with one plant.

It'll be fun...

ill look into it. how do i go about making one?

Do you mean the DIY grow tent? Haven't you ever worked with PVC and or built anything before? It would be simpler than falling off a log.

Measure the maximum amount of space you will dedicate to the tent. Make a drawing of the frame needed that includes all bottom cross pieces for support of a piece of wood or plastic for the bottom and all upper/top cross pieces that would be needed to hang lights and a fan and maybe a carbon scrubber.

Count the corners, top and bottom and purchase one of these for each:



For your 'wall studs' where there would be cross pieces to support the bottom material or to hang lights and fans from count up as many as you will need and purchase these:



For any place where you will have a cross piece but not a 'wall stud,' count them up and purchase these: (or you could just use more of the type above without adding an upright 'wall stud.'



Then measure up how much straight PVC you would need to assemble it and purchase it ... of course making sure everything is in the same size, like 3/4 inch or whatever and cut to fit according to your drawn up plans.

You purchase the PVC glue that follow the instruction on the container and it virtually welds the PVC together.

Purchase the thicker mm poly panda and cover the outside, overlapping it at 'wall studs' and use sheet metal screws with washers to attach it to the PVC. Do the same on the inside.

For the door you attach the poly panda the same way up one side, inside and out, and then use velcro strips for the bottom, top and opposite side of where you have it screwed down with one part of the velcro stuck/stapled to the panda poly and the other part stuck/screwed to the frame. (The door opening has to be smaller than the width of the front so the panda poly can overlap to the next 'wall stud' or corner so there isn't a light leak.)

If you want to section it off into two levels you just add more fittings like these at whatever 'wall stud' and corner and door frame level as needed:



But you only use three of the connections and point one, the unused one, so it will be between the layers of poly and add more straight pieces connecting them and then separate / seal the two sections with poly and add another piece of wood or plastic over it for the bottom/floor of the upper section just as you would for the bottom/floor of the lower section or bottom/floor if you did not section it off.

It might seem like a lot of work but it is simple and it goes fast. You just need to draw it out first and figure out how many different fittings of each type you need, how much straight PVC you need, how many sq. feet of surface you will need to cover in poly (so you purchase enough), get some screws and half decent sized washers. Use light hangers inside or use a little pulley setup to hang your light(s) with some rope so you can raise and lower them easily and buy a small plastic zig-zag cleat to attach the rope to, to hold your light(s) at the level you want. (like this)

and they sell all this at home depot?
All the PVC, fittings included, the glue, the poly and simple pulleys, screws and washers should all be able to be found at a Home Depot, a Lowes or even any half decent sized local hardware store. The zig-zag cleat you might find there, or at Wal-Mart, but you might have to go to a boat supply place because they are mostly used on boats or docks for trying off boats .. but they can be found online too. I think the one I used the picture of was like $4.99. They have metal ones too, but you don't need that much strength.

All the PVC is normal household plumbing supplies ... it is what homes water and waste systems are made of. Any building supply store should have every piece of PVC you would need.

That's why I mentioned that the top cross pieces would need to be able to support lighting, fans and maybe a carbon filter.

i missed the carbon filter
Actually I missed it ... I intended to include it where I said lights and fans, and I thought I had included it, but I guess since I am not a speed typist what happens now and then happened, I got ahead of myself, I thought of what to write but ended up skipping part of it and moving on to what I was thinking would come next.


It was my error. Though now that it says I edited it some might think I added it, but I only found it after I had hit edit.


Additional ... I didn't make an error, I didn't leave out a carbon scrubber .. I went back and hit edit to add it and sure enough I found it: "Measure the maximum amount of space you will dedicate to the tent. Make a drawing of the frame needed that includes all bottom cross pieces for support of a piece of wood or plastic for the bottom and all upper/top cross pieces that would be needed to hang lights and a fan and maybe a carbon scrubber."
