2x 10x 400W flower room build from scratch Hennepdesk style

[Hennepdesk]

This will be a building report of 2 flowering rooms with cross circulation, water preparation and 20x 400W SON-t pia power by 10x 400W Luxgear in an 4,2x3,8x2,2 meters small room.

The room has a 25A 3x 400V socket. 3 small windows. 2 will be blinded and the one on the image will be used to exhaust warm air.

See the opportunities and don't be scared to do some work,

bad ass!!!

Looking forward to seeing the progress on this one. Should be fun to see two rooms spring up from nothing.

 

[Hennepdesk]

First I planned how to divide the space for 2 rooms and 900 liter (3x 300liter water tanks) for watering the plants.
Second I placed some small mothers under 3x 400W (see ballasts) because they can grow during building. The
switch panel is mounted at the wall. 3x 32A will power all.

A concrete sole plate for a 3 brick layer wall to support the gypsum paperboard and two doors to enter the two rooms.
At the left side I planned 3x 300liter water tanks to water the plants.

The first row of bricks is in place.

I cleaned up the corner because I want use the clay to level and create a floor.

Now the real works start. To house the 3x 300 liter water tanks I dig a big hole in the clay.

Its almost dry clay and not simple to dig in. But after one day the hole has the right size for 3x 300 liter tanks.

After a day digging the opening is big and deep enough to hold the tanks.

Till the next update,

Damn Hennep, that is a lot of work you got done in one day. Do you do all your own electric work?

 

[Hennepdesk]

I forgot to answer and reply.

@ ProdigyGrower,

Nothing Bad Ass yet :)

@ Smoking Gun,

Yes that's true. But it keeps you in shape. I do all myself.
Everyone can learn and understand electric work. Start
simple and you can make it complex as you want. Who k
knows what I'll show after this report.

[Smoking Gun]

I have never been adverse to a hard days work. I do a bit of electric work myself, but there are somethings I would prefer to leave to the pros.

 

[Hennepdesk]

Thanks Smoking gun for the reply. Wait till I post the switchpanel I use to control the lights.

I'm gonna add some b/w (black/white) foil

The foil in the 2 small windows preventing someone look in will be replaced. It 's a narrow room for 2 rooms

The battens are covered with duck tape to make them water resistant.

Unroll the foil. Use a Long shaft wall plug to fix the foil with a batten in one upper corner between wall and ceiling

The rooms starts to turn in a clean room.

The 2 windows are covered by the foil but also by a gypsum panel to reduce the noise emission.

Now the walls and doors can be put in place.

The room starts to take shape.

Till the next update,

I am assuming you are going to lay some fresh cement for the floor, but I could be incorrect. Its definitely starting to look like a grow space in there. You may end up with two narrow rooms, but given your style of growing you should still have enough room to get nice yields out of there. Thanks for sharing your process, there is lots to learn in this thread.

 

[Hennepdesk]

Thanks SmokingGun for the reply and thinking. I've chosen an other solution. When you
would make a concrete floor it had to be some 8cm (3") thick and it needed that metal
netting to prevent the concrete to crack. So I came up with this solution.

After leveling the clay a 20mm polystyrene insulation is put on the clay. The clay is not total horizontal.
The water hasto go back in the drain so on 3 meters is 1 cm level difference.

To get a real floor a 18mm OSB panel is put on the polystyrene to spread the pressure and protect the polystyrene against damage.

Now the floor in the first room can be filled with polystyrene and OSB panels.

The floor starts to look like a real floor. Note how small the room is. OSB panel size 250x125mm

Small detail its hard to see the slope but with a small ball you can check ;)

This floor can carry the crates with plants and it won't damage the 1mm pond liner.

[Hennepdesk]

The location for the drain is prepared. Through the drain I will fill the basin and drain it.

Now the floor at the right side for the first room is ready the floor for the second room can be put in place.

It 's the same procedure as in the first room. As you can see is the wall b/w foil till under the polystyrene.

This is how the floor look like. The room will be split in 2 by a gypsum wall.

Till the next update.

[Smoking Gun]

Looking good, I am eagerly waiting for the next update. Are you going to section off the electric and reservoir in another room?

 

[Hennepdesk]

Hi Smoking Gun,

Happy you follow and ask. The answer is no or you should consider the
small corridor I create above the tanks as a room. Let me show you how
and why I dig in the tanks.

I place 20mm poly styrene panels as insulator.

You can glue the poly styrene with pu foam from a spray can

One more row before the tanks are put in the gab.

The first tank in place. It fits seamlessly

Job done. All tanks are in place. Fill the corners with pu foam

Later I'll connect the tanks so I can fill them, mix, pump water from 1 into other and ....
Now I'll place a OSB panel on the tanks so I can walk on them. This safes a lot of space
because the tanks or under my feet ;)

More to come

HD

 

[Hennepdesk]

Note the OSB lid on the tanks. The water tanks are below the floor level so I will use gravity to empty the basins

Each room will have its own drain with 50mm diameter cleanout drain.

The cleanout drain is split to mount it in the OSB panels. The top will hold the pond liner

A 50mm diameter tube is used to connect the water tanks. This will help the mixing of the nutrient solution

Keep a 3mm gab in the OSB panel opening where the drain sits. This space is for the pond liner.

The cover of the cleanout drain will be sealed with silicone to the 1mm pond liner to make a water proof seal.

The drain, flood water in/out and water mixing are in place. Later some extra tricks to add

Ready to make some rooms :) ?

I like your style! Looking forward to see it all come together...
Thanks for sharing

 

[MakinGoo]

WOW!! This room is lookin great.. Very nice layout..

 

[GreenTnT]

very good work A+

 

[Hennepdesk]

@ NaturalTherapy, MakinGoo, GreenTnT

Thanks for the kind words. Update time :)

The wooden support for the gypsum wall is so high that that the space between support and ceiling is 2meter. The length of a gypsum board.

The corridor to walk and prepare the water is some 80cm. The doors are 60cm wide.

On this total view the rooms look big but the image between the reflectors is only 27cm.

The board at the wall is used to mount the ballasts. Also the last 5 ballast for the flowering rooms are in place.

The first 6 ballasts are temporarily for the mother room.

Outside the window is covered. The glass will be removed so the inlet will be 0,5m2. The final lid is on the water tanks.

Till the next update,

sik bro! you got mad skills, aint are not afraid to work! Diggin your set up!

 

[Smoking Gun]

Hennep, that corridor is exactly what I was expecting you to build. Things are really coming together pretty quickly in there. Thanks a lot for sharing, this is great work to see.
