Suspect she'll be ready for the light while I'm asleep in some hours, so I'ma go ahead and put the lights on 20/-24 hours low PPFD

I've got a noisy ass pump I can send you, but, if you've got an extra $120 bucks laying around, grab an Alita pump. Super fuckin' quiet. I LOVE IT. sometimes I gotta put a hand on it to see if it's even running.have to get new air pump
I trust your reviews to be spot on. Alita air pumps is what I'll look at first whenever I setup a DWC.I've got a noisy ass pump I can send you, but, if you've got an extra $120 bucks laying around, grab an Alita pump.

Alita Air Pumps
Alita air pumps are very quiet and dependable. The Alita pumps come in a range of sizes that can drive 6 outlets or over 200 outlets. Alita pumps are excellent for fish rooms and are very easily rebuilt.kensfish.com
Hell yeah man. I'm so glad I went this route. Let me know if you want me to send that pump.Sweet
Gonna start looking into it more, would like to put together a r-dwc system.
Sweet, messaged ya, thanks manHell yeah man. I'm so glad I went this route. Let me know if you want me to send that pump.

So what is the best way to size your pump to the RDWC system you set up?
- Calculate System Volume: Determine the total volume of your hydroponic system, including the reservoir and all connected grow beds or containers. Measure the length, width, and depth of each container, then multiply these dimensions to get the volume. Add up the volumes of all containers to get the total system volume.
- Determine Flow Rate: Decide on the desired flow rate for your system. This can vary depending on factors such as the type of plants you're growing, environmental conditions, and nutrient requirements. A general rule of thumb is to aim for a flow rate that allows the nutrient solution to cycle through the system several times per hour. For example, 2-4 complete cycles per hour is common.
- Calculate Pump Capacity: Once you have the system volume and desired flow rate, you can calculate the pump capacity needed. The formula is:
Pump Capacity (in gallons per hour, GPH) = Total System Volume (in gallons) × Desired Flow Rate (cycles per hour)
For example, if your total system volume is 100 gallons and you want to achieve 4 complete cycles per hour, your pump capacity should be:
Pump Capacity = 100 gallons × 4 cycles/hour = 400 GPH
- Consider Head Height: Head height refers to the vertical distance the pump must push the water from the reservoir to the highest point in the system. If your system has vertical components or the pump needs to push water uphill, you'll need to account for this when selecting the pump. Choose a pump that can deliver the required flow rate at the highest head height in your system.
- Turnover Rate: Cannabis generally thrives with a higher turnover rate than some other plants. Aim for 3-4 complete turnovers per hour.
- Flow Rate per Plant: A good rule of thumb is 50-100 gallons per hour (GPH) per mature cannabis plant. So, a 4-plant RDWC system might target a pump rated for 200-400 GPH.
- Vegetative vs. Flowering: During flowering, cannabis requires more oxygen. You might consider a slightly higher flow rate during this stage.
CAll Hanz and Franz they'll help pump you up.
I bought a DC pump with a digital speed control just in case I wanted more or less. I run it on it's lowest setting until stop adding Agsil to the system. The ph doesn't stay nearly as stable once that's removed from the equation so I up the flow rate to mix the ph-up into the res a little quicker. Early on in the plants life cycle, I worry about hitting the roots with too much flow.So what is the best way to size your pump to the RDWC system you set up?
The smallest Alita will work for you all. 6ASo what is the best way to size your pump to the RDWC system you set up?
Some of the best I've grown so far probablySome fat dense nugs
Indeed, thank you.View attachment 60692
Real nice haul for you also~!
Still a little left to harvest.
Life with children bro, it does get better, I think.So much to do
So little time
Lol
For realLife with children bro, it does get better, I think.
Maybe I've just learned to live around it lol.
One of the things I learned from the local flora is that a tree called Palo Verde(Parkinsonia syn. Cercidium) uses its own bark to photosynthesize.Still a bunch to trim.
Honestly hating trim jail.
Breeding for as little leaf as possible.
