my 3 stages of flower

Ok, new question. I bought a couple chillers to help with my res temps but not sure how I should connect them as they need pumps. Should I use the pump that supplies the sprayers or get an additional pump(s)?

I would get an addition pump and run it using a SS coil in the res. keeping the chiller as a closed loop system. Not saying that is the best way fyi, just how I would do it. The pump capacity would not have to be very large. I work on large chillers and geothermal systems so a bit different but just bigger lol. Does your chiller cycle using a separate temp sensor? The delta t of the water flow through the chiller should be adjusted by valve to achieve max efficiency and will add to longevity of unit.

Hey SS,
I know you run botanicaire and it works great, but I was wondering if you have ever tried synthetic nutrients in any of your systems? I can't find many references of anyone using synthetic nutrients in the these systems. I am currently experimenting with GH, Advanced Nutrients and Dutch Master in different aero veggers and none of them seem to be working well at all and definitely don't come close to the growth rate when using botanicare. Actually, they all look kind of stalled out and not much growth at all, they just sit there like they do not have any nutrients. Not sure if I am doing anything wrong or what so I thought I would ask if you know of anyone ever doing this. I added airstones to the reservoirs tonight, we will see if that changes anything. Also using tap water, so I am not sure if that makes a difference between organic and synthetic nutes. Tap water with botanicaire works fine of course. Thanks.

Only botanicare for years now, I tried technaflora when I started dwc.

Found a great deal(craiglist) on a 1/4 and 1/2 hp chiller. I've got the 1/4 setup and it's working fine on the veg system. Veg totes on a table with drains back to res and the chiller cooling the res. My problem is my flower setup. I've got 2 three rail setups but I've only got one chiller. Really don't want to have to buy another one as this one is a 1/2 hp size and I know its big enough. I was trying to avoid having totes in my tent and just feed the 2 rails from a res outside the tent but my problem is getting the return. How do you guys have your flowering systems setup?

When I ran a chiller i ran one pump from chiller res to manifold that fed wort chillers in each res then to a return line just making a circuit.

So you still had totes that the rails were draining into, correct? And just gravity feed back to the main res?

Yes on RES's but the return was more just pressurized from the pump for chiller

Ok, sounds like you have an enclosed loop there and you weren't running your nute water actually through the chiller

Ok, one thing I don't get is how you guys are going from the irragation type of connectors I'm seeing in pics to PVC?

11/64 drilled hole and screw them in

Wasn't meaning the sprayers. I was asking about going from the barb type connectors that come with the pump( and the associated hose) to PVC

I have never used the fittings that come with pumps. I use the grey thread to barb fittings in lawn irrigation section of plumbing at Lowes. Tons of sizes in different configurations.

in one of your early posts at the beginning of the thread you mentioned using rubber paint to seal your room, what did you use ?

Elastomeric roof coating is what SS told me when I asked that same question. Something like this http://m.lowes.com/product?langId=-1&storeId=10702&catalogId=10051&productId=3013309&store=2634&view=detail&nValue=4294934213

Its a white rubber roof coating for mobile homes. Works great.

Yes it does

did you use it everywhere like paint, floor,walls,ceiling

All but the floors.
