DWC - Light Proofing & Cooling

[mull]

Try to seal up all the painted surface with tape treestump, it will flake off eventually if not.

Good luck there, enjoy.

treestump, ur ment to sand,prime,paint by just painting the plastic it will flake off as mullaway said its just a matter of time

[stonedstump]

It shouldnt flake off because I have wrapped it in duct tape and insulation tape

 

I probably wont sand or prime any of my buckets I will just put duct tape on and then reflective tape.

 

The lid may need a few more coats though because I didnt put any tape on the lid and no light gets through still.

My set up................

80L plastic container............

I painted the outside of the container black , then wrapped it twice in black gaffer tape.

the lid, I taped lino to it with my cut outs for the pots.

I found it was still getting a bit warm , so grabbed some 20 mm ply wood and cut it into squares and painted them white. I sit them ontop of the lid around the pots.

 

I also bought a axial exhaust fan ( 90L per minute ? , cant remember )

for $30 on ebay.........

no more heat problems

 

I have 2 x areration pumps bubling away in the container.

( I think the biggest failing in problem DWC set ups is not enough bubles,

go over board)

 

and check PH often,

I found on my first grow that once I had my PH and temp right,

alge was not a problem.

I think the lino idea is good, i'm going to do that with my nute tank when I get more bubblers going.

 

I have a 5 or 6" round airstone in my bubbler (20L bucket) at the moment and its connected to a 9500cc pump... do you think that is enough air?

 

I was also thinking about putting concrete pavers standing vertically against the nute tank on each side of it and it sits on a concrete floor, that should really keep the temps down I think.

 

What is everyone elses opinion on that?

9500cc is plenty even 7500cc works well see my grow the black pots to the left are using the aquaone 9500cc the black pots to the right are using a aquaone 7500cc
