2 bagseed “grape ape” clone run

Same deal, only thing that changed is I “upgraded” (more of a side-grade) to cdp 8852 and I have a 1/2” pickup that splits to 3/8” pump input. All my plumbing push connect fittings and tubing are atp or John guest.

4x4
560w Cree cxb3590 3500k
44 gal res
High pressure aeroponics
Greenleaf Mega crop @ 1.6EC all the way through first set of leaves to harvest
0.6ml/gal Mammoth p at change
50ml Emerald harvest cal mag at change if necessary

The res gets changed when the top off water equals half the volume of a fresh res or if the EC drops below 1.2, I only add back at 1/8 strength.

My reservoir is always kept at
5.7-5.9pH @ 68-70f and 1.2-1.6EC

Here’s most of the equipment:



Still in veg, just finished getting the new flower tent setup. I’ll be moving them in there and getting the net in tomorrow.

I’m trying a new exhaust fan, ac infinity cloudline t6 without the controller. It’s a dc mixed flow, low wattage.

The new tent is all plumbed and setup. 3/8 supply and return, split to 1/4 going to each bucket

Wow, What a set up. NICE!!!
Now I understand why you couldn’t go into detail previously. Definitely a lot of thought, trial and error going into this one.

What dosing pumps and controller are you using? I want to start work on a DIY automated ph stabilization system then maybe add the nutes later.

Thanks for sharing

Thank you

I got the pumps on eBay, it’s a 3d printed pump head on a NEMA stepper motor wired to a microstep driver controlled by an arduino using the accelstepper library. I get very precise dosing, 16000 steps per mL. The tube size on these particular pump heads is 2mm ID, you can get larger or smaller NEMA steppers and pump heads.

Good luck, mine was fun to build. I’m not interested in helping build another.

Moved them into the new tent and got the net down.

Cant blame you for not wanting to help build another. That thing looks so complicated its frightening. Nice job

Thank you, it was built out of necessity, it's very complex but extremely easy to use and maintain (less than 10 mins a day usually). It looks intimidating but I spend more time handwatering mother plants than I do messing with it.

Just training

Lights are at the top, 20%, going to 35% today.



Chugging along

I got one of these with their temp and humidity controller, it has taken over control of exhaust ventilation from my arduino. Are you controlling fan speed via pwm or is it running full blast?

How do you like it? It’s a lot quieter than the fan I was using. I like it so far.

On/off. I thought about doing pwm, but having it turn on and off has worked so far. I had the big ac centrifugal fans before, so no reason to control with pwm until now. I also thought about doing a refresh on my controller, changing some things and adding some hardware features but I don’t have time right now.

What are you using the arduino to run now?

I built it as a light timer, I used to transition gradually from veg to flower, I don't really do that anymore. I can customize to do non24hr day or pretty much any timing I can figure the math out too. I have 2, 1 is running my party cup comp cabinet, it runs light (cobs, red eod and uv) and a humidifier and monitors temp and rh. The other runs my tent light (cobs and red eod), circulation fans, dehumidifier or humidifier, monitors temp and rh (it used to kick on an exhaust fan when either got too high).

When I ordeded the AC infinity in mid january amazon was ahead of the product release and sent the one that just did temp control although the listing indictated temp and humidity. AC infinity was quick to resolve and sent the right controller so I have an extra temp controler if you can use it.

Their control logic is a 2 stage response, alert level and alarm level. The alert level is set by the user on a 1 to 10 scale in the on/off mode, the alarm level is full on (10). The user sets alert and alarm values for high/low temperature and humidity. The alerts and alarms can be individually enabled or disabled. It will gradually ramp the fan up as an alert or alarm is hit then gradually back down as condition is satisfied. I know I missing some of the features, all in all I like it alot, I am still tweaking the setup but basically I exhaust only part of the air. Fan pushes into tent, tent exhausts to Y connected to a carbon filter and the fan inlet.
