RDWC where to place a water heater

[green beanz]

As the title says really where do I place the fish tank heater on alien pro system

 

It's freezing at the mo and I think I will struggle to hit 18-22c without a heater 

 

Do I place it in the 100l res or in the pot with no plant in it 

 

Can't seem to get my head round it last time I grew in just dwc I put heater directly in pots plants were in and the light on the heater caused my plants to herm so want to avoid that this time

 

So where do I place the heater please

I use a different system and mine is in the res, not sure how alien works but if you have

continuous circulation through the pot/s then  place the heater in your res, should

do the trick. I'd be a bit concerned root temps in the pots, they could still be too low.

Critical temps in the res summer and winter is one of the reasons I gave up DWC.

Thanks for the help 

Will also heat the tent with an oil filled radiator and see if that will help with over all temps

I've got a choice of which RDWC system to go for

The alien silver pro with 20l pots or the black series which is a lot lower spec but I could get it with 36l pots 

 

So what's more important higher specs or bigger pots ?

 

Cheers

bigger pots imo
