Just bought all the supplies for building my new Flowering room. My Plant tray is 3'X3'. with a 40 gallon Resevoir. Mylar walls. 5,050 BTU ac unit, inlet fan, outlet fan, and and oscilateing fan. 400watt HPS light, with (6) 43 watt CFL lights and one T-5 light for the side lighting.

Some of the people in here say your plant will tell you what it needs.

Well, if you notice in my pictures. I have covers for my rock wool blocks, to keep the light off of them. I just took a peak under them. They have roots growing out the top of the rockwool. they look nice and healthy. Real white and fresh looking. Anyone understand what my plant is trying to tell me?:weedpoke:

Just did a Nut Change out today. My plants are starting to drink more water now. Not like when flowering, But I can see the increase. These plants are now 14 days old. This Northern Lights really seem to like to grow short and fat.

I just started building my flowering room today. I hope to have it built by sometime tomorrow.

Here are a few new pictures.

The one plant there in the soil is the same strain and just as old as the hydro plants. What a difference.

I just finished building my Flowering room. It is 4'X10'. I used the white and black 6 mil Poly, I bought at the Hydro store. The white side reflects 90% of the light, and the black side lets zero light through.I have my AC unit already installed, It works great. Tomorrow I am connecting my Water filteration unit so I will no longer have to buy and carry water. I will have R/O water with the turn of a valve. I also installed one of those light hangers. The ones where you can easily raise and lower you lights with no effort at all. Now I will not have to battle with the high temperatures anymore.

Here are a few pictures of my new room.

Wow I think you are on a roll,Plants look great.The pix of the AC You will have problems with it down on the floor.I live in a hot state too and we did that samething and the exhaust into the room will bring alot of condensation and it drains out of the ac on to the floor.Thats a window unit and it needs to be up higher,cool air fall down.It would be better to exhaust it outside if you can.You said the temps are 90 to 120,the exhaust will up it alot and wet too.Thats something I learn the hard way.Cause alot of mold problems in the house.But thats a good setup to control the grow area.I liked that bath tub setup too no worry of a flood.Keep us posted. Peace

It gets to 90-120f outside. Inside my place it is 80f. And humidity is only 30% inside my home. So there should be little if any condensation dripping from unit. But just to be on the safe side, I have it over a metal pan.
I ran it for 4 hours last night, and not one drip of water. And yes cool air is heavier so it is down low, but having the unit down low will make it cool my room better. Cool air in, Cold air out..... Hot air in, cool air out. AC units do not work very well when they have 120 degree air entering them. In that 4 hours of running it, I was able to get the room down to about 66f. So once I start my HPS light up, I am hoping I can keep the room to 75-80f. My last grow I saw temps in my room all the way to 94f. And this was not even during the hot part of the year.

If humidity raises above 40% I will buy a dehumidifier. But I really doubt this will happen, because A/C units dry out the air, they do not put humidity in the air like a swamp cooler does.

I am thinking about moving my plants in there sooner then flowering stage now. Maybe next weekend when I have to do another Res. Change out.

Crazy, I am thinking where you live is a lot more humid there here. Like right now outside humidity is only 3%. (Yes, 3%). I live in the Desert.

Oh, another thing to remember, the rest of my home is also Air Conditioned, which means that larger unit will be removing moisture also. But I will deal with what happens when it happens. The unit can not be routed outside. It is what it is.

DOH!!!! I screwed up on my design. I bought one of those 20" square fans for my outlet fan. At least I did not cut an opening yet for it. I just noticed that it will let in light to my room. As it is, my room is so dark, you can not see your hand right in front of your face. I need to get a blower fan with some flexable ducting.:S5:

I am going to see what happens, just running the AC unit. It has an inlet and an outlet also.

My New grow room is almost operational. All I need is to hook up all my six ways, wait for my R/O system to make 30 gallons of R/O water, and put my plants in here. Think it should be tomorrow night.

Few picture of my plants new home.

P.S.
DAM THESE R/O filters are slow at making water. I guess I am going to go buy that float valve also. I am timing it now on how long it takes to fill a 5 gallon container. I am thinking it will be about an hour. I have a 55 gallon plastic barrel for my water storage though, all I need is the float vavle to turn it on and off.

This R/O filter is cool though. Now I do not have to go buy R/O water and carry it into my house. All I have to do it throw a valve and WALLA 30 PPM water.
