I'm in a small tent so no concern with loss. In the early part of this grow, so room for height isn't an issue for now.

I was just curious in general terms.

I'm going to be draining my two buckets through 2" pvc in a short, straight line to my res. Do you think this will be adequate to keep up with the flow directly from the chiller through 3/4" lines?

With ppfd being equal, is there any disadvantage to having led lights farther from the canopy?

Impressive!!

Thanks, I appreciate that. I enjoy problem solving particularly with outside of the box solutions. The water bath chiller works well and could be adapted for RDWC, I simply lack the necessary space in my closet. I'm using 3 of the Mars ts-1000. Down the road I'm thinking of upgrading, but I...

Too late now, already got the chiller in today lol. Money isn't an issue. I'm single and retired. I don't drink, no motorcycles, boats etc. Growing for me is a hobby and entertainment that I really enjoy.

Thanks, that makes sense after thinking about. So I'll need 2 pumps then, one to circulate to the chiller and the other to the buckets. Would I be correct in thinking they don't need to be the same size?

Thanks for your reply! I have a 2x4 tent shoe horned into my small bedroom closet. I'm using 2 Hydrobuckets that hold 4 gallons to the bottom of the root plug. These are the only reason I got into DWC. With the the side reservoirs it's never necessary to lift the plants up to do maintenance...

I'm planning on possibly upgrading my DWC system to recirculating when my current grow is finished and have a few questions. I'd like to reuse anything I have now if possible. I have a cooler I want to use as the reservoir. Are there any pros or cons to having an insulated reservoir? I'll be...

I'm in a second run of their Blue Dream Auto. First was a single and I'd give it an 8, nice well behaved compact plant that produced 230g. This run doing two to see what other phenos might show. So far, at week 4, one looks like she's going to be a major stretcher even prior to flower :(. Have...

Very interesting information in these PDFs! I know I don't have anywhere near the reservoir capacity for my canopy size that they recommend. Since it's early in my current grow I'm considering a new strategy. I think I'll try doing straight RO water add backs until my PPMs drop to between 65...

At first I thought the only thing volume would affect would be temp swings. After thinking about it, I realized I wasn't taking into account a living organism in the equation. The plant is taking a smaller percentage of dissolved solids out of 26 gallons than 3 gallons.

What's your waters starting ec? I'm using ro and my current ec is .6

I really didn't see how volume could buffer ph swings either but I had to ask.

I have to admit that ph stability is very appealing, especially at lower ec levels in early veg. Do you find your ph is more stable even at lower nute concentrations?

I'm having trouble seeing the advantages of RDWC over DWC, for me personally, in a 2x4 tent with just 1 or 2 buckets or totes. It just seems like extra components and nutes to deal with for 1 or 2 plants. When I have 2 plants going full throttle, I do complete nute changes every 6 to 7 days...

Well I don't feel too bad now, I only use a meter but I do keep a spreadsheet lol.

It's just a plant, It's just a plant. Thanks!

I just got a complete and identical Apera pH/EC meter to have for a back up. I replaced the probe on my original as it was close to 2 years old 3 months ago. After cleaning and calibrating them both I decided to compare their readings. The temp, EC, and ppm are very close between them. But there...
