Here is what I have to work with: a 3x6 tray, 2 600's, PBP bloom and grow, cal mag, big and chunky perlite.

I am thinking a recirc drip system w a 60 gallon res, canna coco mixed w/ 25% perlite in 2 gallon containers. OK so far?

I need reccomendations on a pump size, a ph and ec pen, how to keep the coco in the pots, and how to keep the coco out of the res.

I'm gonna start off w/ a ph of 5.5 and work my way up to 6.0. EC will depend on the strain and stage of growth but I have a pretty good idea of where it should be.

I have been a soil grower since I started and am looking to automate things to make it easier. I have been looking into this for awhile and after reading Gratefulehead's thread I have decided to do it. Thanks.

Is there anything I'm missing

I use a 25w submersible sump/drain-pump that can deliver 2750L/h at a height of 3m. (Low pressure I think, but enuff too push through a 120u mesh-filter and deliver water to anywhere from 1 to 60 sites 50cm above).
A nylon stocking at the return+line, use windowscreen or such in the bottom of the pots. Usually coco is drip-fed to waste, but some people manage to recycle too. (I'm trying it right now, but I cannot say I'm satisfied. (Also tried a little higher EC, like 1,6 peak, but it was way to much...-Think I'll stay from 0.7 in rooting 0.9 in veg/induced bloom and peak at about 1.4)
The coco coir is extremely efficient in delivering nutrients to the roots, so I recommend using less to gain more.

Otherwise I think your setup is fine.

PS! Read a little on coco without coco-designed fertilizers in the sticky threads on top of coco-forum three.

good advice Kenny Lingus, less is more nute wise in coco. if you want to setup a drip feeding system, you also need a good inline particle filter. drip lines will get blocked by the smallest particles of coco. so using a stocking on the end of the return hose is only the first part. the particle inline filter is the second more important part. even when not recirculating it is advisable to have a filter between the pump and the drip lines. the main thing is to make sure that the pump you get is suited to the type of drip system you chose. some are made for very strong pumps only, so be sure to get advise from the guy selling the drip setup about the pump capacity needed.

Thanks guys for the help guys.
Gauismarius - I learned to grow in soil from BOG on OG and it worked out great from the start. I'm sure I can't lose with your help as well as the the others hanging around this forum.

My goal is to keep the medicinal qaulity and to increase yeild. Keeping it medicial quality is very important and I hope the move to a more organic nute than PBP. I do not use any chemical pesticide's or boosters. I feel med patients dererve no less for medicine. I don't plan on using a dripper. I'll just use a feeder tube. I like the idea of a coco mat under the pots but I don't know if they benfit more than beilng able to move the plants around?

Here's what I'll be growing.

yes moving the plants is a big help to make the most of the light. i can't wait to see your set up in action, sounds cool. you will make amazing tasting product if you make sure to starve the plants of N towards the end and with a few days of plain water to finishup.

Sup Brain ,
just wanted to add , make sure to airate your rez , 'specially using organics . MetaNaturals works well for us in conjunction with other nutes .

hey bro... good to see you're finally takin the plunge coco works great.

your set up sounds perfect..

pump size is kinda dependant on how many open feed lines you plan on runnin. if you're using 2 gal pots it sounds like you'll be in the 18 to 24 plant range so a 500 gph mag drive pump would work perfect.


they come with a foam filter and it's worked fine for me....no blocked lines.

recirculating works great cause you can water til your coco fully saturates at each watering with no waste.

to keep coco in the pots and out of the rez I've been using coco mat. I buy the 4x8 mat and hand cut liners for the bottom of each pot... kind of a pita but I get zero coco bits in my rez. the coco mat liner goes inside the pot so you still have the ability to move the plants around or remove them for pruning or whatever. I tried burlap cloth from home deopot but it appeard to start rotting- looked black and mushy after a while so I stopped using that. Window screen seems like it could rust

for meters I really like the bluelab truncheon for both ec and ph.. I've had a few hannas and I like the blulabs better. a ph of 5.5 to 6 works fine. if you need some ec reccomendations let me know cause I believe we're growin cuts off the same mother

coco specific nutes are NOT superior to other top brands.. not easier to use either you can do just fine with the pbp line.

Steel- Thanks for stopping by. I'll look into Meta in the future but I wanna use what I have. I got the PBP when I thought it was organic like it says it is.

Forty- I have a real solid game plan so far thanks to you. I think one feed line per pot should do it. What do you think? You gave me some ec levels before I saved them to a word doc. before my pms were turned off for not having 50 posts. Talk to you later...

does the strain have a name, brain?
is its purple temp, nute, or genetic specific?
i'm starting my own 2 gal drip show and would like to know.

I'm quite sure that you never go soil again.
Sounds good & promising,
I'm just waitin' you to start.
