Hey guys, new to RIU but active on GC. I run DTW with a 55 gallon res. Just expanded to a 4x8 table. Here’s a peak at my setup

Hey man, I got questions about your setup, I like it a lot and may build mine very similar. It's between a setup like yours or a ebb and flow table like Jefferson is using.

I'm gonna build a 4x 16 section

Are you using the white pvc as your manifold? Looks like all your lines run directly from that?

Did you put sides on the plywood? Or is that ice and water wrapped up the actual wall? Love this idea of using ice and water as flood tables are fkn expensive. @ renfro used pond liners and 2x12 but I had zero luck finding pond liners around here today

Where is your waste going? Piped to floor drain?

What size pump and what timer are you using?

I'm gonna be working with 49 plant count, so trying to figure out what I wanna do and how I want to run my room.

Yes the manifold is 2” PCs and has 20 outlets.

At the walls the ice shield is wrapped up. Where there isn’t a wall I built a curb

Waste is collected in two bins under the table and pumped out into a holding bin to get disposed of daily (not fond of this but my sump is clear on the other side)

You need a pump with enough lift to get up from res and through manifold. Mine is rated for 6’ lift and I wanna day it’s 585 gph.

Timer is Nearpow digital timer. Runs 1 min increments and I tune flow with the valves in pvc manifold

Hey guys

Can someone run through the buffering precharging method for me

I'm using 3G fabric pots

Do I just mix a solution that's approx 300ppm and flush 10g of ph water through the pots?Am i aiming for a certain ppm number in my runoff?

I just read a few spots that said h&g was 60ppm out of the bag, could this be accurate? seems low enough that it wouldnt require any flushing?

Can the plants then be planted in the pots shortly after the flushing?

My tap water is 50ppm

Buffering info. You got this. 8-)

https://cocoforcannabis.com/how-to-prepare-and-buffer-coco-coir/

Most high quality coco claim to have done some rinsing and buffering.


Why You Need to Buffer Coco Coir
There are cation exchange sites in coco that will interfere with nutrition until they are buffered. The cation exchange sites in coco naturally come loaded with sodium (Na) and potassium (K) cations. However, the Na and the K are only weakly held to the exchange sites. In the presence of calcium (Ca) or magnesium (Mg), the sites will release their Na or K cations and lock onto the Ca or Mg. These processes are known as “cation exchanges”.

3 gallon fabric pots. Straight coco precharged with 1/4 strength nutes. I use the 5 lb bricks. I don't bother with perlite. Nutes consist of calcium nitrate, a micronutrient blend, and monopotassium phosphate. Use calcium nitrate and the micronutrient blend for feeding in veg. Add monopotassium phosphate when you start flowering. Magnesium sulfate and potassium sulfate used midway through flower a few times. Humic/fulvic acid a couple times in veg. I never use calmag as the calcium nitrate provides all the calcium needed. Any balanced nutrient will have calcium and magnesium. Calmag is just calcium nitrate and magnesium sulfate which are both already present in the nutes I use.

I also use blumats so I never have any runoff. When I was doing drain to waste I never checked the runoff. It's not necessary as long as you know what your doing when you feed. Blumats and coco is as easy as it gets. Even a cave man could do it. Plants love it.

Thanks xtsho

I plan to run straight coco, precharging at 300 ppm was what i was told orginally.


Will be using GH flora series H3ad formula or the GH Nova lucas formula. Atleast until my megacrop gets here

I like simple lol
