Reason I asked is that I bought a cheapie that was only like 1/2 in thick of carbon. So, I hooked my fan up to it and it got most but not all of the smell. What happened was I was pushing the air too fast through the filter, not giving the charcoal enough time. What I finally had top do is run it slow, like 100 or so cfm and exhaust the filtered air in the same area (scrubbed) Works fine. I just wanted to warn you that you can't fun your fan full blast, gotta give the smell time to get caught in the carbon. Big time filters like the CANs are like 3" thick so no problem.

How are you going to filter than? You will need to place the filter in the tent up high maybe? If you can't , you will need to construct a chamber where you duct the air from the tent to the chamber with the filter in it (think of a big trash can with the filter in it). Air in the chamber goes through the filter, out to the fan (sucking). Or, some people will duct the air from the tent directly to the filter that is placed outside, than ducted to the motor. (sucking) Not exactly what the filter was designed for but works.

I used the Lucas Formula for a long time and always had the same N deff during stretch. It's too low in N for good growth IMHO. The one thing the Lucas has plenty of is Mg. 2% Mg is a lot higher than a lot of other things. Cal-Mag has a secret ingredient that really helps plants like this out, Nitrogen. (2-0-0) 
Bump up the micro and watch the yellow stop.

Same as what I said. Dude doesn't have an inline carbon filter but it will still work, but not exactly as intended in the design of the filter

oh I gotchya my bad. There isn't any other way to connect to the filter other than the way you shown in the attic. Thanks,
I hear some people will stick the prefilter in the ducting of the filter when used this way.

dead on bro, that cal-mag allows you to run your bloom nutes the day you flip to 12/12, many makes this mistake and it causes premature yellowing. one thing i have to say is that plants depending on strain absorbe tons of mag, my recipe calls for the mag in my veg/bloom nutes, cal-mag and still i run sweet which has sulfur and more mag, and many times it takes all that to avoid the mag

I think what he meant was that Lucas has plenty of MAG and that the true effect of cal-mag in this situation is that it is supplying the much needed Nitrogen (2-0-0) so the recommendation is to just increase your GH micro a bit. It is 5-0-1. Loaded with N and Cal. Is that right?

cousin morris doesnt like lucas formula, boxing do you notice this issue with one particular strain or is it all your plants?

Correct.
. Nitrogen is not the enemy, contrary to the paradigm. Mg is essential because it is required for Nitrogen uptake. Mg def plants display slight N def (yellowing at margins) even though the N is available because the plant cant process it without Mg.
That said, many times over I see people adding Mg when all they really need is a N boost. In my experience, N def is much more common than Mg def. Like I mentioned above the plant reacts in the same way to both deficiencies so determining which one it is can be a challenge. The advantage cal-mag has is it gives both. The PBP line rubs me wrong though because the base line has NO mg in it forcing you to purchase their additive. Grr.
You can mix a great soup with most any 3-part nute. No additives needed. GH, AN, whatever. You just have to toss the "feeding schedule" out the damn window and feed a 3-1-2 blend in veg and a 1-3-2 blend in bloom after stretch. I use a 1/2 bloom, 1/2 veg mix for wks 2-3 of bloom but that's just because I happen to dump on that schedule and it is an easy blend. If you are looking for an easy 1-part mix, dynagro rocks.

whats up Mr Duke... I originally bought thouse to fit perfectly over a 5 gallon buckets...When i began to do more research I saw that the Ebb & Grow systems out there were using 2 gallon buckets... I kept em and its worked out perfectly so far... they leave a nice gap a little less than an inch and a half.....enough for a nice root mass to develop and dangle.....the rings also make it easy to lift the plant out if need be...... The only thing I purchased was the Controller....55 Gal drum craigslist 25 bones... buckets...(2 gal home depot) clamps, hose, etc.. hydro store...
