Grow room concrete floor

[queequeg152]

Que and smokin erb pretty much summed it up.

If the basement is climate controlled there is really not much
floor insulation necessary for a concrete floor. If it is not, then you are probably looking at a whole new gorilla that should be dealt with
while building a "dedicated" grow room if you know what I mean?

Basement floors are 6 ft or so underground. Unless you are dealing
with perma frost in alaska... ?? ( just an example) It should be no big deal if your growroom is at ambient temps.

building on actual permafrost is an entirely different beast.

its a very complicated area.. and one im only vaguely familiar with, but from what i understand, the ground is so unstable that you either need skin friction piers deep enough to find stable frozen strata, or you need to build on an adjustable surface foundation.

putting an uninsulated slab ontop of permafrost would be like placing a hot plate... upside down, onto frozen mud lol... if you can imagine that one.

the surface of a permafrost, depending on the soil type, tends to heave up and down with the changes of the season so they build these sets of 3d space frames under structures... they elevate the structure, thermally breaking it from the ground, as well as allow for access to jacking points to re level the structure.

foundations are interesting.

I had a grow for years in a basement. With awesome results. The plants loveed the winner.

I know nothing about permafrost.. just throwing an example out there.. glad you know what you are doing with it..

for us midwesterners.. basement / coal rooms rock.. ehh most of the time

Epoxy floor coating!

Probably not practical in a home grow, but the advantages are boundless.

Clean white floor. Seamless. Mold resistant. Antibacterial. Slip resistance.

These floors are perfect for indoor growing. I cant stress enough: Get it professionally done. If you are in the northeast send me over a PM.

I believe DHF suggested to me that I paint the floor with a moldicide type paint, maybe made for bathrooms or something. I'd have to find out what it was exactly.

I'm also in a basement. Used to keep everything 6"+ off the ground, but lately I just toss it on the cold concrete. Haven't really seen any negative effects as a result. Mine's just painted white and black/white poly on the walls. Sloped floor for drainage, so I just let my run-off run to the basement drain. Although, I water with very minimal run-off. 2%, tops.

DHF/Krusty's paint suggestion was Sherman Williams Mildewcidal flat white bathroom paint.

Basement floor is the best you can do for a grow. Don't worry about the floor temps since it's a wash. In other words the heat you need apply in the winter is less expensive than the extra cooling you will need without the cooling of basement in summer.

Oh and don't paint your floor, it's concrete and needs no paint which will peel and look like hell in no time. Save the white paint for your walls, nothing better for spreading lumens.

Why not use DryLock white paint then go over it with a bathroom or outdoor type paint to really seal it in. I use water heater pans with cut PVC tubing in the shape of a triangle which keeps 20 gal smartpots pots 2" off pan. You can even link pans together with tubing and vacuum runoff out easy with shop vac.
