Just made an improvement on my old grow room. I made 3 walls and painted them with latex paint white colour. Even the floor is white. Set up a 600 hps and 350 watt leds beside it. The space is 5 feet by 8 feet and it gives me space to walk around the plants in the middle. Its super bright compared to before. I like it!
NEVER keep even pressure on a roller. Always keep more pressure on your leading edge to avoid lines . Start from the top and finish at the bottom and always keep rolling on the same direction. You're creating a texture difference between the levels of applied paint when painting from side to side and up and down. Migro does a reflection test between Mylar, Flat White and Gloss white. Flat White and Mylar always perform better.
I bought a bunch of mylar emergency blankets for my room. Work great and cheap and have a thermal quality. Just watch for burn from reflection depending on your setup.
Best TIP: You should have went with Benjamin Moore Bathroom & Spa, that is the best for Mildew & Mold resistant. Yes, it could be $10-15 more, but why redo it again & again. That cost lot more. Just my 2 cents :)
If you do not enclose the ceiling...you are allowing all the work to keep out moisture is going up and over and also below. To get behind the drywall...
+Fafnir Icingdeath When I did a google search I found some thing that says other wise Full gloss = 85% - 100% Gloss = 60% - 84% Semi-gloss = 20% - 59% Low sheen = 5% - 19% Flat = 0% - 4%
I do white walls and mylar flooring. Reflect those Ray's back up to the plant and side walls. You'd be surprised how much light you are losing when your floor isn't reflective..
What the "flat" camp doesn't realize, that the reflection of light is relative to the angle of the view. If you have a glossy surface stand in an area and notice the direct reflection (the hot spot) have someone put their finger on that spot. Now move around the room and notice that the light (hot spot) will change, depending on where you are. Now imagine a room full of people. The reflection is hot for each person in a different spot. So this proves that the light does not just hit a glossy surface and go in only one direction. It goes in all directions. The light may be almost the same though. One is more focused and more intense and flat will be more diffuse and less intense. Where light waves are lost is in traps. Irregular texture in which it can not reflect out of. Much like the egg crate effect reduces sound waves.
great series .. this brings back memories, projects I have done few years back .. (too bad I wasn't doing videos then) @8:29 that's what I prefer, to actually remove the light switch cover (using screwdriver) for painting the wall .. so that in the future, if someone ever want to to replace the light switch cover with different shape or smaller size, she/he don't have to worry about finding a paint to touch up the unpainted part of the wall
my rooms runnin 40% relative humidity so no worries man..if u go LEDS like i do they run hotter than CFL n dry the air kinda so..awesome man..will be watchin it come along.
Regular drywall and drywall compound do not hold up to moisture! Even if you seal this. There's a reason code in most cases requires a blue board/green board in wet areas. This is not a long term solution. Save yourself time and frustration and do it right the first time.
@Medical MJ I understand you would think that but working at a large college with hundreds of showers used repeatedly I will repair a half dozen a year due to moisture issues 95% use regular drywall as a substrate because its cheap. It may last years but it eventually fails. It keeps me employed. And in commercial situations it doesn't hold up. Ask yourself which would you rather have in your home? In some homes paper based products are used for sheathing. Just because its used and meets code in some areas doesn't mean it should be done. Do it right once. But what do I know I've only been in contruction for 22 years.
@ 9:00 that's what happens to me! I tried it by not removing the switch cover so I put the blue paint tape all around it, but the paint still got through the little crevices so I still had to remove the switch cover anyway to clean up the edges.
Exposed ceiling won't be growing any mold due to a fan being on, as well as the fact that mold only occurs when water sets on the wood. People get humidity and moisture confused. You can have 100% humidity and zero mold as long as there is adequate airflow. Hope that makes sense. I will cover this topic more in the upcoming series.
Great job you guys, I'm glad you painted the room the way you did. It is all looking really nice and thanks for not painting that light switch plate. lol.
I will take you up on that! Let me see, school, business, wedding plans, when are you going to fit that in....and don't say honeymoon!!! lol Thanks guys. Can't wait for the grow room to progress a little farther.
With all the water and humidity in the room I would be worried about the exposed 2 x4's on the ceiling, are you planing on painting them as well? It may be a good idea too just so that you don't have to worry about rot or mold developing in your grow room. Also, as far as insulation goes, are you worried about losing any heat through the empty spaces near where the wall and the unfinished ceiling is? I love watching your videos and I would be interested in your opinion on this, thanks!
with adequate air flow there won't be any moisture just setting on the 2X4 this will be covered in the "humidity, heating, and air flow" portion of the series. I would encourage people to just be patient, because there is a HUGE difference between water setting behind a board, and having humidity. Humidity harms nothing, but water that sets stagnant behind a wall will do the damage.
Hey Luke! I am working on a project now too so it is interesting watching you. Here is some good information on reflective surfaces. It discusses flat - semigloss - and gloss paints. Hope you can check out this link: www.rollitup.org/t/grow-room-qustion-mylar-panda-film-reflectix-foil-white-paint.237642/
+Rainbow Gardens thanks for the link. I'm converting an unfinished garage and that answered my question about how best to finish my walls. I'm going to put insulation up, and cover it with panda plastic instead of finishing the walls. :)
yes, it does. Dampen it up a bit with a little water then roll it in the paint...doing this helps tremendously when removing the paint off the roller later on after you are done painting, if you need to reuse the roller. is water based paint?
@Medical MJ you're right! I just flung black paint drops all over my green door and the glass panel while rolling black onto some rebar for my guardrails...
GLOSSY whites do not reflect light as efficiently as FLAT white. Semi-gloss paint for example, only has the ability to reflect between 55-60% of the light. Also important to remember when using paint is that any smears or blemishes on the surface take away from how reflective the wall is so care should be taken to avoid marking or staining the walls. Titanium white paint is very reflective; however it is usually only used on reflectors due to its high cost.
+OverGrowTheUK When I did a search that is not what I found. These are the numbers that I found when I did a search. Full gloss = 85% - 100% Gloss = 60% - 84% Semi-gloss = 20% - 59% Low sheen = 5% - 19% Flat = 0% - 4%
+XInfinity2013 those figures make no sense tho, it's obvious even flat white reflects a lot more than 0-4% that's pretty obvious, can I ask where you got those figures , thanks
OverGrowTheUK The reason why flat white paint is better when growing is because there is no added stuff inside the paint to cause the gloss thus the more "usable" light reflected that the plants can use is higher. To our eyes and some other things gloss paint does reflects more light but to the plants it doesn't. "The light has to go though the gloss hit the white paint then bounce back go though the gloss again before it goes to the plants." Remember its about the TYPE (Wavelengths) of light that the plant sees that it can use that matters. As far as I know there are 3 things that we can see from lights. - The colour of the light (Kalvin) ie redish/yellow and White - How bright the light is - The reflection off of surfaces (When light bounces off of surfaces)
I hope you aren't leading some people astray with this series, or at least with your painting suggestions. I have to agree with those who have said flat white is best and mylar would be terrible. You will end up with some major hot spots. Throw a couple 1000 watt HPS lights in there and you'll see.
I do not intend on leading anyone astray what so ever. It is a subject that will always have debate because everyone has a different way of doing things. I was on the phone and spoke to 3 hydroponic specialists and basically took an average of everything they were telling me. I am by no means a pro, but I learn from what people tell me, and if it has worked for them, there will be no reason it doesn't work for me. Reason 1 why I don't use a flat white - Flat white is diffused light, not reflected light, and diffused light basically just means soft light. Softer light does not mean stronger light. Reason 2: High humidity = mold and mildew, and flat white paint has texture that can cause mildew, the texture to the paint is what makes it flat, and it also gives it surface area for water and humidity to set on. Thus causing mold or mildew faster than a glossy texture. I am going off what they told me, and I again am not saying you are not right. However, everyone has different opinions, and they all do, not just you. So I am going by what I think is most common. HOWEVER This may change as I continue to do more research for a more common consensus.
I did not say or imply that you were intentionally leading your viewers astray. After several attempts to reply to your comment in a constructive and polite way, I've determined it best to let it stand.
FesterWerks Well my issue would be that you were making a retorical question. Just like you could be asking a robber in your house, "I hope you are not robbing my house" but the only reason why you are saying that is because you already are assuming he is robbing your house. You assumed I was giving people false information, and that upsets me quite a bit. If you have a differing opinion, I welcome it because there are more than 1 way to have success, but instead of providing any constructive addition, you say, "I hope you are not leading people astray" that seems quite intentional to me.
***** Again, I can't give any substantive reply to your comment without offending you more. And just by saying that, I'm sure I have. So again, I will attempt to let it stand.
