aquarium supply places not cheap pet stores. Tropical fish stores carry carbon in buckets for CMEMORY. its the same stuff that they use in Air filter carbom
 
Yea man ebay has gallons of carbon. It's by FAR the best deal and will give you enough to likely last quite awhile. Those small containers are all MASSIVE ripe offs.

some people use kitty litter also and actually now they have new kitty litter with charcoal which might make that idea even more reasonable. I'm sure some mixture of kitty litter and charcol and or odor crystals would work well and be very available. We just need more experiments on the subject I think. Though few people want to mess with their odor control once it working. I've never done the litter thing, but i imagine the kind you chose is very important.

I though you could not refill the carbon scrubbers I have a big one and the hydro guy told me I should just buy another one?
 
They can all be refilled technically since they were assembled somehow. Some are just very easy to refill and others are seal and not meant to be refilled easily.

The guy probably told you that because carbon filters are fairly dirt cheap these days but you can still save a lot of money doing it yourself. It is however easier t just pick a cheap pre made already filled filter and hook it up.

I made the Sun is Shining type and it works well. Very cheap to make, but the trick is buying the carbon in bulk otherwise you may as well just buy one like the hydro guy said because refilling with anything but bulk carbon is not worth it. When they sell you those things they are selling you them with bulk carbon prices so using aquarium carbon to do the job add a lot of expense. In fact most of the cost is carbon in almost any carbon scrubber. .. cept very small ones.

It really doesn't matter with the carbon scrubber. They used to be expensive but OG and the rest of the DIY world seems to have regulated the prices a bit. If you have a small grow buying one for like 60-80 bucks makes a lot of sense. If you want the most cleaning for you dollar however I think the DIY scrubber may clean more air or at least has a lower air resistance design. Let's all think sun is shining once again for that great tutorial, but it should be added that unless you buy carbon in bulk you may very well spend more to make a DIY srubber. Though hey sometimes you need one ASAP and you could perhaps put one together from materials in town in about 2-3 hours including shopping.

A cheap place for supplies is mdhydro.com I think they have scrubbers if not you can probably find them on froogle. bchydro.com has a lot of stuff. I dont know if I've ever ordered from them or not. I get em confused now with similar names and such.

Carbon can also be cleaned or homemade. People often make their own carbon when they make filters for home alcohol brewing.

To clean charcoal is two steps:

boil for 15 minutes. the heating changes the charge of the charcoal and causes it to release all the debris it has gathered.

rinse in cold water for 5 minutes. the cold changes the charge back again and reactivates the charcoal.

If your willing to goto the effort, there is a substance that you can re-new by simply putting it in the sunlight. ZEOLITE!

Now its a bitch to find a source to buy it, with lots of sites selling liquid zeolite, some nutty health BS thing, but as a mineral, comes in a few grades. Coarse is good for filtering water, and fine is for odors, and with the odors you just put the zeolite in the open air with sunlight hitting it to release what it had trapped.

Works really good according to an old overgrower, never used it personally. Its not too common for purchasing, and I recall its more expensive than charcoal, but its better for the environment and cheaper in the long run.
