Do it with Pierre

Thank you for watching my video! Please comment with where you are from so that I can say hi. If you want to you are also welcome to tell me about your system, or what you plan.
What size reservoir tank would I need for 20 vertical grow towers, with a flow rate of 10L to 25L per hour? I plan on using dosing pumps to maintain PH and EC values. Could I get by with two 70 gallon tanks? Always using one and having another as a backup, ready to be used. Or should I just use one 140 gallon tank? The information you provide is very relevant to the subject. It provides me with the help I needed for a project I have been planning. I purchased your Learn Arduino With Pierre course, it was everything I hoped for and MORE! I will be purchasing Aquaponics and Hydroponics course soon, because I am very interested in Vertical Grow Towers. The information is provided at a reasonable price.
Hi
I am planning to build a 12 gully/channel NFT system. This has helped me for the pump calculations. Although I still cannot find a good source to decide my sump/reservoir capacity. If you have any comments, it would be a great help. Thank you1
Baie dankie. Jy mag maar n Afrikaanse video maak. Daars baie van ons.
Very helpful , thanks a lot !!
Great video. Thanx for the easy explanation.
Hi, I’m using DFT system , and I want to ask is it okay if I let my 4500L /H run on maximum for a 200L growbed? My head is just 1m and it says the the graph that the flow rate is gonna be 3500L/h if I circulate too much it’s not gonna have any negative impact right?
I'm using 2 5 gallon buckets for 2 vertical towers.. Thank you!
Thanks a lot Pierre. This was very informative and helpful. It took some time to understand though.Thanks again.
this was the perfect video for this. answered 100% of what i needed to know! thank you alot!
Excellent!
Clear and concise, thank you.
One question, the requirement for a vertical system, you state it at 10-25L/H – is this the same for a 2" vertical grow-pipe and for a 6" vertical grow-pipe? This is the magic number I've been searching for and haven't been able to find anywhere else.
I trust that you've tested this flow rate, so that's where I'm going to head.
Again, thank you.
Thank you very much.Very useful video.
