You want just general comments? First - you have a great little beginner system so take my comments in stride, as they are just suggestions. Given you have a RDWC setup with waterfalls, the air pumps/diffusers are going to be overkill. My rule of thumb is if you are using a water chiller, air...

They make all manner of sizes of dehumidifiers, ie., you can buy bigger ones that have bigger evaporators. If I understand correctly, OP has a 4 bucket RDWC, so I'm assuming 5 buckets total. That's exactly what I have - 4 13 gallon EZ stor containers with a reservoir that is the same. They...

Whatever you do, don't follow the illustration listed right underneath your first post in this thread. It was probably created just to demonstrate what it kind of looks like, but in reality, you want all of your pvc connections that are branching off t connectors to be exactly the same length...

The way I do it is I convert everything to minutes. So if a pump does 500 gph, that's 500 divided by 60 = 8.33 gallons per minute. Now we look at the total capacity of your DWC system. You mentioned that the tote will hold ~40 gallons. With a 500gph pump, you would recirculate your entire...

No offense, but that is a highly inefficient way to chill your water. For one, refrigerators cycle on and off, and they don't produce enough of a drastic temp change to really cool the water in your wort chiller. A much better and easier way to do it is with an old (or new) dehumidifier. It...

You should always allow your PH to drift within a certain specified range, rather than constantly adjusting it to one specific ph value. Nutrients absorb at different ph levels therefore you want your nutrient solution to experience a range of values for optimum absorption. Ie. Don't constantly...

Ya. And I should've clarified. The coils aren't sitting in reservoir water - they cool water that gets fed to 2 immersion wort chiller coils that sit in my reservoir, so the two systems aren't mixing liquids. You would be surprised just how well it actually works. I get ice forming on the wort...

I've got one that's been running for just over a year and a half, cost me $60 on ebay for a brand new humidifier and even if it were to die right now, I would say I got my moneys worth

Do a search on the Internet for DIY water chiller using a humidifier - there are even a couple videos on Youtube about it. Here's the instructions I followed: DIY Chiller from air dehumidifier Basically, you can get a used humidifier for really cheap, you just pop off one of the panels to...

Yep. There were some informal studies floating around several years ago that actually showed the DO content of your reservoir was higher with simple surface agitation vs. air stones. As mentioned, I put little screens in the ends of my T connectors to aerate the water even more, but it's not...

I myself have two rdwc setups with waterfalls. I was running both waterfall and airstones at the same time, and then figured I could do away with the airstones and just depend on the waterfall returns for oxygen and agitation. I put little screens in the ends of them - like what you would find...

Looking good! Is that waterfall aeration or are you using stones and pumps?

Hello CannaFish, Here's the link to the study that was conducted by Black Dog about LST. If you don't want to read it - just check out the graphs they posted. HPS vs LED Leaf Temp

While there are some fluctuations to optimal LST, depending on strain, there was a university study conducted a couple years ago on optimal LST for cannabis. The conclusion was that 25 - 35 C was considered optimal for photosynthesis to occur. That would be 77 to 95 F. I've seen other more...
