So you’re thinking of setting up your own grow room? Good for you, that’s an ambitious adventure, but it definitely pays off. There are some great reasons you might want to consider making your own growing space rather than buying a pre-made tent solution.
First of all, it CAN BE far less expensive. If you choose the right material, and take your time, make sure you do everything conservatively and only once, you can make your own grow room for cheap. One of the most important things to make your own room is choosing the best reflective material for grow rooms.
Second, you can make it a lot more customized and unique. If you are looking to turn that perfect spot in your house – whether a whole room or a small space – into a grow, doing it yourself can be easier. You can shape the walls in non-rectangular forms, so that the whole space flows a lot better.
Lastly, it’s fun. Not everyone has the inspiration to make their own grow room. If you have the will and capacity to do this, then it’s a really fun project. Definitely something worthwhile to do, and you can show your friends later – they will be impressed.
All right, so now that you have decided whether or not this is for you – we can begin. Let’s start off with the single best reflective material for grow rooms.
Mylar - #1 Best Reflective Material for Grow Rooms
Mylar is the best reflective material for grow rooms hands down. Why? It’s cheap, light, quite durable, and extremely reflective. Those four characteristics basically kill all the competition in one unbeatable, unstoppable swoop.
I mean, what more could you want from any kind of material than those four options? Most mylar is at least 95%+ reflective, but that depends on how much you want to spend. If you get the really good diamond style mylar wrap, you can get up to 98%, which is extremely efficient. Even 95 is really good, so only spend the extra money if you think it’s really worth it!
On top of that, it’s just so east to work with – cutting, taping, pasting, wrapping – whatever you need to do, the mylar can do it all. It’s definitely a sweet material, definitely the best reflective material for grow rooms. You can get a big sheet of it for quite cheap, it’s a super-efficient material to work with, so check it out if you’re interested. I’ll include a few different grades depending on how high-scale you want to go.
Aluminium Foil - #2 Best Reflective Material for Grow Rooms
Aluminum Foil is a decent alternative if you want to cheap out, but it’s really not the best. Generally, it comes in at around 88% reflectivity on the bright side of the foil. One side is dulled, one side is bright, so make sure you put the right one up.
There are many disadvantages, so I would not consider this the best reflective material for grow rooms. For example, it is tarnished a lot easier than mylar, a lot thinner – easily ripped if caught the wrong way. It’s obviously a decent amount less reflective too. If you get something acidic on it – a lot of plant feed is slightly acidic – it will tarnish and get even less lustrous.
Aside from that though, I honestly think it’s still a pretty good alternative. It’s a household item so anybody can set this up within a day easily. It’s still easily pasted and worked with onto all kinds of surfaces. Just make sure that you tape up all the seams, or else you will catch the edge and rip it right off potentially.
Astro-Foil / Reflectix - #3 Best Reflective Material for Grow Rooms
Astro-Foil or Reflectix is a pretty decent alternative. Although it’s pretty expensive, it’s probably the strongest, most durable reflective material on this list. This makes it the best reflective material for grow rooms where you need good durability.
The reflectivity rating varies, but it’s usually in the 75-80% range, although maybe you can find ones which are slightly better. This will most likely be your most expensive option just because of how reinforced it is, how strong the material is.
I used this stuff when I built out a van into a camper, and it worked very well for that. I can say with my experiences that it is indeed quite reflective, and does a great job at insulating. For this reason, you can actually use it as an insulating-reflective material. For tents which need to hold in heat / cold, I might recommend this as the best reflective material for grow rooms.
Mirrors are a strange option. I have never seen anybody use mirrors before to be honest, but I mean, if you have a small grow room, it’s definitely doable. It’s the closest to 100% reflective that you can buy, so it is basically a perfectly reflective material.
Although it’s heavy, can’t be bent, is expensive, and also quite breakable, it’s a cool idea. If you bought those little mirrors, you could easily line the inside of a little grow environment for not too much money, and have a 99% reflective interior.
I don’t know, it’s definitely not the best reflective material for grow rooms, but thought you guys might get a kick out of it. It really is the most reflective thing on earth, especially when you take price into account, so it might be worth a shot.
Reflective White Paint - #4 Best Reflective Material for Grow Rooms
Reflective Rustoleum S-22066W Titanium White Paint is a really cool option. It has the ability to reflect around 80% of the light, and it creates a nice even surface which reduces the accumulation of hot-spots. This is definitely the best reflective material for grow rooms when it comes to reflective paint. This is made for making traffic lines on the roads, and is meant to reflect the headlights of cars.
Therefore, you know that this is some serious stuff. I mean, if our government uses it to ensure safety, I’m sure we can use it to grow weed. I have heard of people using this stuff, and they generally report pretty good results with them.
Not only is it easy to apply, but it also dries really quickly so that you can get the plants in there. I would still wait for the smell to go away before putting them in so they don’t get some kind of toxicity. Just fire up your inline fan and let it suck all the grimy fumes out for a day and a half, maybe two, and then you should be ready to rock and roll.
Obviously, the only downside with this material is you need some kind of good surface to paint on. It has to be hard – or at least semi-hard, so that it doesn’t keep flexing, which would inevitably ruin the layer after due time. However, if you want to use pain in a big grow room, man, this could be your choice for the best reflective material for grow rooms.
Well, I hope I have given you guys a lot of inspiration. There are so many ways you can create a nice, very reflective grow room, and these five options will get you off to the right start. It really depends on how big your room is, the budget you have, how hard you want to go, and just what you like out of these. Thank you for reading about the best reflective material for grow rooms.
