heath inspired test prototype (aero)

[farmhouse cat]

Cool obsevations growclean. I love the input. I dont neccessarily agree with you on the more light at the end , although i think that is more strain dependent. Yes this thread is titled "Test prototype" so its a work in progress no doubt. Veg times and canopy management will make all the difference.

Im a test hampster, and like to try new things. "I get bored easily, it may be my downfall.

I dont guarantee anything. I just like to take what i learn and see where it leads me.

Ive already shattered my flat 1k watt grows and i still have 12 plants left in my system to harvest. And that is 6 different strains, all different sizes and only 3 walls.

FC,
It looks interesting and fun! I didn't read your entire thread, but went through each page at least. I know that you had a couple of problems and are still improving. I don't know hydro or aero at all, but I have grown with a slightly larger similar vert setup. I think that something that would help you a little is getting everything organized and cleaned up a little on the plant side. I know someone mentioned a scrog and this was key for me. The front of our shelves did use 4"x4" (size of the openings) metal screen (these were screens used to strengthen concrete.) They can rust a little, as they are not coated, but it was slight, not severe and did not seem to cause any harm to the plants.

The screens were used to grow the plants out of and then tie to. This kept all buds at the requisite distance from the lights. This combined with alot of trimming and plucking produced a 10' tall 4 sided wall of weed. This took alot of time and effort, which is why I have stopped this style. But, it yielded alot in a small area.

Good luck and I am sure the next round will be even better!

Im still trying to figure out a screen configuration that would work in this system. Thanks for the ideas.

ok i love this 4 racks 60 plants just one 1k light...wtf i got 15 on the floor in the same space....i am gona copy you...this can be done in soil right...

wow howd i miss this thread, lovin the aero walls. just a few things, in my opinion you are better off forgetting about a lung room, from what ive seen you dont have any problems getting the proper equiptement.

you will make much better use of space using the entire grow area for plants, just need ac and some fans for the bulbs.

also i got my biggest increase in yields by letting the plants get a bit overgrown, then constantly training, tying, and slowly defoliating the plants all through flowering. Also use a screen to train them into and evenly spread all the brancheg. Like the guy above said, A LOT of work, but great for yield.

...one more thing, if you want a cheap DIY res chiller you can use an old water cooler. just take it apart and have the coils sit in your res, works like a charm.

I finally got moved into the new house! What a pain that was, and during the hottest week of the Year!

My test run harvest is mostly done drying. Ive already filled 14 jars of the dry stuff and have alot of trimming left to do. Im very happy with the yield, even though i havent weighed it yet, i know its gonna blow the socks off my horizontal 1k grows!

My garage is an empty canvas waiting to be built!

I have a little dillema i hope you cats can help me with. My new flower room is going to be 640cf.
I already have a 10'' max fan from a previous room. This 10'' max fan and can filter 125 combo will get me 879 cfm. This will get me 1.3 room exchanges a minute. Not quite the 2x a minute you really want, not to mention using a fanspeed controller.

Or spend $400 and buy a 12'' max fan and the same filter that will get me 1340cfm. just over 2x a minute.

Money is a little tight at the moment, but i really want to do this the best i can.

Any opinions would be helpfull?

Thanks

add an intake fan.

 

[megayields]

What Bobblehead said......I am a huge proponent of massive air exchange!

Nice work FC....you totally rawk with the omage' to Heath Robinson!

 

[farmhouse cat]

add an intake fan.

Even with an intake fan you still cant extract out more then the extraction fan is capable of. (or risk positive pressure leaks)

Im just wondering if exchanging the room 1.3 times a minute is fine.

Or is it justified to spend $400 on a bigger fan to get to that 2x a minute?

Thanks Mega! Im building out the new room at the new house as we speak! OMAGE TO HEATH!

Well it is for a scrubbing aplication and you will know if the smell is too strong but that won't be until the 2nd half of flower at the earliest, so I think you have a while before you have to invest in a bigger fan, or you'll find out you don't need it.

 

[farmhouse cat]

Thanks Hydro..you always have the simplest explanation that sets me at ease. I like that!

 

[Dreamz_Of_Green]

u cant go wrong with the great heath robinsons work ....

Nothing stopping you from keeping your current exhaust and adding a second exhaust, is there? Instead of 1 bigger fan, why not a second fan/scrubber just like the ones you've already got?

ok... 640cft x 2 = 1280cfms you want to move...

879 cfm extraction - 400cfm intake = 479 cfm of negative pressure. 879 + 400 = 1279cfm your moving total... You'll be fine adding a 6" intake...

this way you can control humidity with the intake... by adjusting RH% of the incoming air. Anyway, it's what I would do....

I see. I didnt know you could do the math that way. I always thought the extraction was limited to what it could pull out of the room? Not how much you can push in too? I was planning on having 2 6inch intakes, and adjusting them with a speed controller. or maybe one off one on or whatever works.

Thanks bobble.

?! r u sure about the math bro ?
if u have a 879 cfm extraction how can u move more than that ?!

Thats what i thought?

 

[bobblehead]

I'm talking about air displacement... So if you're take air out faster than you're bringing in, there won't be a problem... Yes, you should have a larger exhaust, to create negative pressure and so you'll have air coming in passively as well as actively. Trust me on this, all the pros bring in cool air actively. ( unless using CO2 of course...)
