How much does a carbon scrubber reduce CFM? Does a carbon scrubber dampen the sound of a fan? Does it keep light from escaping/entering?

What is wrong with doing this? Don’t just say your not supposed to cuz it’s a fire hazard. Ive heard people arguing both sides of this. Some say they do it with no problem. Some say it’s a fire hazard. The Sun System 4 accepts both and theres no fire hazard, but I don’t think its designed any...

Ok ive got a few questions about internode spacing. I know that indicas are supposed to be bushy(tighter spacing) and sativa taller…. Ive also heard that using mh lighting for veg makes a bushier plant while hps makes them stretch more….BUT Which has more of an impact on node...

I’ve heard of using the hand test to see how close you can put your light to your plants but I was wondering….how can I tell if it is too much? Just because its not too hot for my hand doesn’t mean that it wont stress out a small seedling…

Ive got a few questions about cloning… What is the best time of day to take cuttings? Right before lights on/off? Right after? Sometime in the middle? Do any of you clone straight into soil and get good results? I will be using rootone on the cuttings but I want to throw them straight in the...

I recently got some fox farms ocean forest soil but i got a huge bag of it and it was way more than i thought. The size of the bag isnt a problem but im not going to be using most of it for awhile. Im going to start like 2-4 plants tommorow or the next day, theyre germinating now. I was...

Just wondering, if you want to use two different nutrients at once to water, do you combine them into the same gallon of water?? lets say for example, i want to use FOXFARMS growbig and BigBloom, and there suggested amounts 1 tbs per gallon of growbig, and 2 tsp per gallon of bigbloom. how...

im trying to build somewhat of a custom DIY cooltuibe. its for my 150 hps and i have a few quetiosn. i want to make a box to keep the light in. i would ventilate it with an exaust and/or intake fan and there would be a plexiglass or other glass bottome so the light can be covered and put...

hey zen, what size computer fans were you using with those carbon filters?? also, how much cfm did you loose with them on?

ive heard that frozen bottles of water (a.ka. ICE) placed outside the box right near the fan intake can reduece tempuratures. it wouldnt be a permanent solution but it could definatly help. im trying to build a grow box myself and its about half the size of yours. i image that my light(150...

that sucks about your seeds man. good luck, with the others. im trying to plan a grow myself, its so much more work than i anticipated, not to mention money. Probably cause i want to do this perfectly and i am trying to make sure nothing can go wrong to kill my plants. i want to be able to...

i have a 150 watt hps but i dont want my plants to grow tall and stemmy. Im under the impression that using HPS for vegging is bad because it makes the plant stretch instead of grow compact and bushy... Entry Detail so i was wondering if it would help me to throw a few of these blue reptile...

wtf happened???? i realize this is over a year ago i just want to know how it turned out... did your plants recover or did they die?

hey those are some pretty decent nugs considering its from an aerogarden. When i first entertained the idea of growing bud i thought an aerogarden would be ideal but i didnt know how much of a yield i could get... guess thats my answer. ANyways nice job with that. And your new tent looks...

hey i know that was from awhile ago but i was wondering how thats possible???? im plannign on building a growbox but my design involves having two fans with carbon scrubbers on them in the growbox for odor control and ventilation..... is this a bad idea?? if its going to make temps shoot...

hey bigd, i was wondering about a few things. If i used a HPS for this method, would that make the plants stretch? Or would they just stay small because the 12/12 lighting cycle? Also, i was wondering which worked better for you in this scenerio, soil or hepy buckets? one more...

Ok ive got a good question... Would it work well to do this 12/12 lighting entirely with an HPS light? Im aware it might not be necesarry, but im just wondering because HPS lights are supposed to be best for the flowering stage. And since this is flowering basically the entire life of the...

Firstly, this is for a very small scale operation. Its a small growbox about 2 x 2 x 3 ft and its going to have an input fan on the bottom and an exaust fan on top with a DIY carbon scrubber attatched. I was wondering if it would do any good to place an additional fan with a carbon scrubber/or...

let me rephrase this, since no one responded. Would it help to kill the smell anymore if i were to place a fan with a carbon filter inside the growbox? Im hoping this would kill some of the odor before it even leaves through the carbon scrubber/exaust fan

Hey Gypsy i was going to put a fan inside of my growbox to blow on my 150 watt HPS. Will this really increase the temp inside? How?
