The table is plywood with film surfaced ice and water shield as waterproofing.

What is the wattage of your lights? Nice setup bud!

Each 4- qb120 light puts out about 234 watts so 700 watts total. I’ll be testing a new light from Vividgro at the end of the month. Hopefully I’ll have the co2 and environmental controls all set by then

I would highly recommend washing any coco regardless of whether they claim it was pre washed.

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

Yes, Cal/Mag at full rate, you can add low nutes and pH'ed.

Thanks, do I have to wait a certain amount of time before I put the plants in the coco ?
Or can I plant directly after ?

Buffering info. You got this. 
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”.

Interesting how the ph needs to be higher than 6.2.
To Double-Buffer Coco:
To Double-Buffer Coco:
- Prepare buffering solution:
- Tap water may be used for buffering solution
- Add at least 7.5 ml/Gal of General Hydroponics CaliMagic
- Electrical Conductivity (EC) of the buffering solution should be 1200-2000
- pH of the buffering solution should be greater than 6.2

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.

GH and more. Some exhaustive information... I found it helpful when I ran GH.
