I have reading a lot about ph to understand it better for my grow and it seems I have learned a few new things: I should not force the ph to 5.8, rather if it is within 5.5-6.5 I should leave it. I should monitor the ph and check it 1-2 times daily. A range of ph is actually better than being...

I understand that for PH meters there are ph 4.0 and 7.0 to calibrate the solution. I am looking at a TDS meter and would like to know what I need to keep it calibrated. I saw a brand that had 1000ppm and 342 ppm solution. I then wanted to see the General Hydroponics version as they are usually...

I'm sorry I don't understand the last sentence at all. In the video he's using a 700GPH pump using 5-gallon buckets, I'm guessing to create more oxygen in the water through pressure. I understand it may not be ideal, but I already bought the pump and lost the box so can't return it, and don't...

I have recently changed my RDWC setup to copy one I feel would be better for me. I will be using six 10-gallon totes and a reservoir. Rather than using an inline pump that flows water into the reservoir, I will have an inline pump pulling water from the reservoir. It would then pump up and...

Yeah my pump is submersible? Does anyone have a link that explains the different methods of RDWC? I have a reservoir and two buckets all on the same line and I'm trying to figure out the best way to make this work. I also have a chiller

I don't understand

The only thing that makes me feel like more of a newb than posting in this forum is asking this question. How do I install my submersible pump in my RDWC system. That's right, I asked it. I always thought it would be self explanatory when I got the pump. I always understood the farthest bucket...

I'm running a DWC setup. A lot of the answers are intuitive, but I want to make sure I have a complete understanding. I assume the size of the container/tote/whatever matters. Or is it the amount of water? How much space the roots have? There are 14 gallon, 27, 32, etc. What's a good size for...

Why did you send a link to the ph 7? Why not ph 4 or 10? Do you know the answer to any of the other questions?

These are some of the ones I was looking at. http://www.amazon.com/Oakton-EcoTestr-Waterproof-Tester-Range/dp/B004G8PWAU/ref=sr_1_7?ie=UTF8&qid=1423707204&sr=8-7&keywords=ph+meter...

I am looking to buy all 3 of these meters and would like to know all the required maintenence for them. It seems for the PH meter I need PH 4 and 7, cleaning, solution, and storage solution. I also see ph 10 solution, do I need that? If I regularly calibrate it and keep it in the storage...

I bought a couple tents, one for veg and one for flower, so that I may have a perpetual harvest. I then realized I wanted to use a scrog, and 70-80% of the scrog has to be filled before switching to flower. Does this mean I MUST use the same room, or is there some other way to still get a...

I am going to be doing an RDWC grow and will be attempting a scrog for the first time. From what I gathered it seems like I put the scrog up during veg, possibly 3 weeks in, and switch the plants over to flower when the scrog net is 75-80% full. The point of a scrog is to pull back vertical...

I did. I took him to home depot and lowes and neither had the parts we needed. I think it was the rubber gasket they were missing, so I wanted to make sure I was ordering the correct item online that's all. Any other glaring issues you see?

Can I use this with 1.5" PVC? http://www.horticulturesource.com/hydro-flow-tub-outlet-straight-fitting-w-2-gaskets-1-in-bag-of-10--p22656

Do you say that because there is something wrong with my setup? What is it?

New setup advice anyone?

Anyone else have any advice on my new setup? Pumps? AIrstones? PVC?
