How to Build a Hydroponic Grow Room

So you are wanting a hydroponic grow room, and you’ve seen the grow tents, but you’ve decided that there to costly and also take to much room up and also don’t provide somewhere to grow your plants before the flowering cycle.

Making your own grow room is easer and cheaper than you’d think, that grow room diagram you see above, is my own

Indoor Grow Room Setup , that’s used all year round.


Hydroponic grow room diagram

That top compartment you see in my hydroponic grow room, is used for all me clones / plant cuttings and vegetable seedling, also for raising some garden plants too.

Then the grow room compartment to the right, with just the two fluorescent grow light was designed for growing one mother plant and six hydroponic clones on, as its got the same grow height as the main grow chamber has, which is a great bonus to have.

Making a compact grow room is not only very cheap but also if your using one of the hydroponic setups, then almost all make some noise, “its just unavoidable” so making your own grow room just makes sense as you can grow more in less space.

If your planning on using an outbuilding like a garage, then using a grow tent will be intractable, inn less you live somewhere that’s nice and warm “all year round” as grow room tent kits are a bugger to keep warm in winter, where’s insulating your homemade grow room is an easer enough job, with the bonus of easily being removed when that whether warms up.


Why Build Your Own Hydroponics Grow Room Setup!

The hydroponic grow room you see in the diagram was very cheap, about 40 pound or 60 dollars “wave to cousins in America” so still half the price of even a cheap hydroponic grow room kit I think, but of cause that’s not including the fluorescent grow lights, which are simply piggy back on to one another and plugged in a timer that’s setup to 19 hours on and 5 hours off cycle.



Grow Room Ventilation

Its one of the mistakes that many folk make when first starting with hydroponic grow rooms, buying the wrong inline ventilation fan can be disastrous not only you wouldn’t be supplying enough fresh air to your growing plants but you also run the risk of mildew if your humidity is higher that 50%, particularly if you’ve got big dense buds “smile” which you should have if your using a +hydroponic growing system+ the grow system I’m using at the moment is a +homemade Aeroponics system+ and also my aeroponic cloning system which cost next to nothing to also build.



Growing Mature Hydroponic grow Room Plants

The compartment you see to the right is where I grow them aeroponic cuttings on, there simply grown on in a+ hydroponics drip system+, “its just a modified air lift” that grows them plants on until there’s plenty of healthy roots showing, then there transferred over to the main growing chamber where Aeroponics takes over.



Grow Room Flowering Chamber

I’m using Aeroponics in me grow room, and it works just like that Amazon Aeroponics system that you’ve bound to have seen abound, except its using very fine misters and not the sprinklers you’ll see in some online videos, as sprinklers can easily become entangled in roots or just become stuck, also sprinkers make a right racket when running.


Fans In Your Grow Room

Its an important part of your hydroponic grow room, having a couple of desk fans running, their wall mounted to save space and set to number one on the fan speed, just enough to mix that air up and prevent even the largest of buds from getting bud rot, with just a little air circulating round.


Grow Room Flowing light

Its all to often overlooked, or when your first starting out you simply don’t realize just how much heat these indoor grow lights knock out, until its just to late, and summer come round and you find that your grow room plants have just stopped growing as them temperatures are just to high, so your plants just stop breathing, to preserve water “hydration” as water will start evaporating faster than your plants can suck up though the roots, so that’s why I use what’s called a cool shade, so in summer I can ventilate all that hot air strait outside the hydroponic grow room and in winter I connect the vent from the top “vent that’s in the ceiling of the flowering chamber to the back of the cool shade” that way your getting the warm air though and hopefully keeping that temp above 70F.


Co2 In Your grow Room

Using co2 in your grow room is easy enough, mine runs on bottled gas and not bottled Co2, once you’ve got everything in place, all that’s need is to take samples of enriched air and test it with a Rae system test tubes, its an inexpensive Co2 testing kit, which once used and you’ve nailed your timings for releasing Co2 to 1400 PPM concentration to your grow room Co2 level, although can only use in a well sealed grow room as summer temperatures can easily push grow room temp above 100F.

Plants can tolerate higher grow room temperatures when co2 enrichment is used, unto about 92F, so in summer I simply use my Co2 generator inside my greenhouse instead which is where the pictures been taken.

P.s Above 1800 PPM and Co2 Becomes toxic to plants and above 4000 PPM Co2 Becomes toxic to Humans. The one I use, and most other folk too, is Mylar, it’s a highly reflective polyester film that comes in varying thickness, and reflects about 95% of your grow room light.

Using Velcro to hold your Mylar in place so’s it’s easily taken down for cleaning, just remember that Mylar tears real easily and also creases easily too.


C3 Anti Detection Film

It’s a very specialized material, and comes with a specialized price to match too, come with the same properties as the normal Mylar, but with the added bonus of also reflecting 90% of infrared heat which will make your grow room invisible “well nearly.”


Matt White Paint

It’s a great option for your grow room, matt white paint will reflect 75% of light back to your grow room.

TIP- if you choose white paint then buy kitchen/bathroom paint that has fungicide added to it.
