you can set the scrub filter in the corner. lay it on a shelf or hang it on the ceiling. a scrub filter you don't exhaust anywhere. It just cleans the air in the room. so anyone would have room for it. My buddy has 2 mounted on the walls of his grow and his is in a walk in closet.

I get what your saying friend and it will work fine especially in a sealed room w a scrubber........but it is counterproductive to run an intake fan and then more fans with a scrubber instead of just exhausting/filtering/exchanging the air in one unit == cheaper and less gear.

I run neither and I would kill for an exhaust option......no question

Not really. having a scrub filter on the exhaust Imo defeats the purpose of having a filter. I constantly run the scrub filter fan 24/7. The intake and exhaust alternate every 15 min. If the filter was hooked up to exhaust. It would stink half the day. You don't run intake and exhaust at the same time. That would be idiodic and not achieve anything. I have 6 innline fan on filter. Then 2 booster fans for exhaust and intake.

That's a fucking strange system you have going on there, I've never heard of anyone doing it that way before. My exhaust is a 6 inch vortex attached to a carbon filter, and the intake and exhaust are hooked up the the same temp controlled circuit. I also have another 6 inch vortex with a separate carbon filter that runs all the time, regardless if the room's air is being exhausted. The main problem I see with your set-up is when you're on your intake phase, you're creating positive pressure which means wherever there are small air leaks in your room, any bit of intake air that hasn't had the chance to pass through the carbon filter will be pushed out and start to smell. You always want a slight negative pressure so that this does not happen. By the by, what's up BB? Nice looking plants, man. I don't know how you grow them like that with those toy lights. J/K

Thanks for answering my question about ventilation. This thread is so huge it seems to have all the answers.

If you use an intake you only need one fan, the one hooked up to your filter. If you run an intake, you have your intake fans, plus the fans for the scrubbers. It's way more work for the same results. You could easily just set the scrubber beside your tent, or from the ceiling/wall, where ever, and have it pull air out of the tent. Then just simply make in intake tube going from the tent to your fresh air source.

No one is saying fresh air is bad, we're just trying to show you how it's inefficient to run an active intake and then have a completely different setup for cleaning the air when it's much easier to run a passive intake via negative pressure and just have the one fan.....

If the negative pressure in your tent was great enough, a single pasive intake coming from your fresh air source is the way to go. No timers, no extra tubing, no extra fans.... nadda.

Hahaha, thanks man! I love my Christmas Tree lights... lol

I have a vortex on my cann filter running 24/7. Almost 4 bills. the 2 booster duct fans are $25 each. I have an industrial carbon filter I got for free on my intake to block bugs and debris. But if my scrubber was on my intake it would filtering outside air. I did it this way because of alternating fans. It would stink. It would take 5 min to pull all air into the filter plus the off time between. I run my intake and exhaust only when lights are on. Its would be too cold in there running with the lights off. The booster fans are only 180 cfm's and in no way create enough negative pressure to do anything at the size of the room. No tent. Its just enough to bring in fresh air and exhaust hot air. I want to run the scrubber 24/7 for smell and air quality. Also the booster fans are much more quiet. The intake goes through a window and the exhaust goes through the wall up to.the roof. The scrubber sits a few feet from the corner of the room. Im in an apartment and have new neighbors. Yaaaaa....

Ok, these bitches are out of control... need to devise a method of raising the light. They're only 12" from the light now.

Hash Tips with Beef !

What's up folks!

So, I have raised the light back to about 20-22 inches. I like the coverage a lot more. Lots of bud sites, lol! So many bud sites...

Hi Beef, i been looking your grow journals, i want to buy a led light for a dr60 i have looked the af 135, but im thinking in 2 bs240, what do you think is better for quality buds and yield? with 2 BS obiusly i will get more yield, but what do you think is better (i have an ebb and flow with AN Nuts, i grow with sog with beetween 25 to 35 small clones in a 2' x 1' 4'' tray.

two blackstar 240
www.blackstarled.com/219.html

or one af-135
shop.area51lighting.com/specials-and-clearance-/10-a51-135.html
what spectrum do i need for full flowering (i veg in another chamber)
How much watts do it gives, because its says actual power 230-285w depending of the spectrum, what is an average yield i could get from one of these?

Hope you can guide me!

Thanks a lot!

The AF-135 is much more powerful than x2 BS240's.

Same appox. wattage, 280W ish, but the Heliopto diodes used in the Area 51 panels are og much higher quality, and produce much more light, than the diodes that BS uses.

No contest, go with Area 51.


I'd use the 4250k diodes, with red supplementation.... 620-660nm reds to give you a 'spike' in your flowering spectrum!

Thanks a lot for helpiing me, i have bought one AF-135!

Ill make a grow journal when it get to my hands!!

Thanks again Beefbisquit!!

Shit I`ve been busy lately

Fucking work 1st they seam to want to fire me and then they fold to all my demands, good news is I will soon get sunday`s off for "church" (that`s code for roast beef, weed and top gear) lol

Anyway looking good beef !

I`m around 2 weeks off a harvest and thanks to helping out other people and some bad luck I`m a filter short of what I normally have and short on space too.

Was considering doing the whole freezer thing for my whole yield

Anyone know a way to shorten the space of time it takes to get the green ready to be frozen without making it shitty ?

I guess I`ll have to dig out the old 5" inline I have somewhere and get a filter for it should have a cupboard or some space somewhere where I can put them for 2 to 4 days to dry.

Whats the "freezer thing"?

Freezer curing! It's mentioned...somewhere in here... LOL

Much faster than air curing, and preserves more flavor and color!

Update time folks!

Looks great.........You may hit impressive #'s from the pics I see/great job beef.......Long veg=== bigger yields every time.......++++rep for the fine ladies

how many days into flower??? strain??? I forgot sorry..........

Hell Yeah Beef 2 monster plants there I only have room for little ones,



I love the white but next time I`ll be a tiny bit more careful with the monopotassium phosphate lol

Damn beef those bitches look nearly perfect, I hope my grow is even half that good lol
