I find top drip to waste requires less water/nutes than ebb and flow. I find also can be less work and time with res changes and volume. The other plus is better results. (at least in my experience)
Little confused.
Sounds like your going to use fenceposts cut holes in them and stick in netpots.? or that was the plan for the original setup?
Other options are go top drip to waste in trays or go with buckets.
stick 3.5 gallon buckets inside of 5 gallon bucket. The 5 gallon bucket catches the waste. Or can also go hempy.
If using coco the larger root mass will probably produce better yields than a 3" netpot.
(unless you do large plant numbers)
Hope that helps.
Yes the original and probably still plan is to cut 3" holes in the pvc fence post and drop netpots in. Each netpot will either be filled with large diameter perlite or coco.
I don't want to do 5 gallon buckets because I won't get close to the yield I am wanting. Its way too messy with an uneven cannopy and way too easy to get spots of mold / bud rot I've found. Air circulation isn't able to get between all the plants. I lost 2 oz of my last harvest because of that... and 15oz from a 600w is no small feat~!
Basically this is the setup I'm invisioning:
8 posts laid side by side, 4 on the left and 4 on the right. The furthest outside post will be 12" higher than the most inside post. And a 4" drop from post to post. This creates a stadium look and allows me to feed only the first top post on each side and let it run down subsequent posts if so desired. (for the dwc recirculation idea).
If I use drip to waste than I will just run drip lines along the posts and tilt them slightly at one end to drain into a container.
I think the drip to waste is the way I want to go but I'm having a lot of trouble finding good info on what size drippers / how often to feed / how long to feed at once. Ect.
I checked out that thread you suggested bobby, his plants are 20x bigger than what I'm doing so the numbers don't really help me : (
Imagine this, except drip to waste or rDWC:
ok I understand you now. Your going SOG style. the details help to see what you are going for..
I am familiar with dr greenthumb's setup. Your taking it a step further with v shape.
Make more sense as now why you want to use netpots and posts.
Top drip setup with 1/4 lines and drippers. DIY thread here.
Built that setup for rockwool, then ended up switching to coco. Can design it to go along with the setup you build.
I think the drip to waste is the way I want to go but I'm having a lot of trouble finding good info on what size drippers /
I like to use 1/4 lines and the drippers in the thread above. You can also just plumb the lines directly to the pots. (o rockwool cubes)
My res is about 15' from the drippers. I used a 1800gph mag drive pump to ensure even coverage.
how often to feed /
I prefer multiple times a week with lower ec. Also depends on strains so you dial it in from there.
I like to follow a feed water feed water schedule with smaller containers. Some strains may do feed water water feed, if there are not big eaters.
how long to feed at once
for coco, I shoot for 20-30% runoff at each watering/feeding.
Lots of more info in the coco forum. feel free to ask as well. I have used top drip with coco and rockwool.
do not see why your setup would not work. but I would imagine the roots are going to hang from the netpots down into the posts.
That could potentially ruin your crop if something goes wrong with the roots. There hanging there and that could mean higher performance but if they get too hot etc then problems can happen. (unless you add misters or foggers, then you can get more performance but also have to keep that in check) Seems like your trying to keep it simple and reliable.
I would maybe think about mounting some type of pot that sits within the posts. The pot rains into the post which then catches the waste
That way the roots are within the coco (or rockwool) in the pot and protected and safe.
Maybe something like this.

Just a thought, may help to make thing more reliable.
Hope that helps.
Yes, but then water in between feedings. Intention is to not let the coco dry out.Most things I've seen so far say to feed an hour after lights on and an hour before lights out with ebb/flow and drip systems. You only feed twice a week? I would think that would cause the roots to dry out too much?
I like it and use a dual res setup. One is r/o water with a float valve to keep it topped off. The other res is for nutes.What would you think about a dual reservoir setup? One reservoir is for the nute mixture and one reservoir of RO water pH'd to 5.7 or so. Run the RO water on the misters between each plant and do sort of a mini flush between each feeding. Worth it? Benefits / cons?
