    It’s handy to have both outside the tent firstly Cos it’s easier to manage adding nutes and stuff once your plants get big and it’ll be closer to the chiller if your using one. Chiller works quite hard at the start till you got a decent canopy. And header pot being outside will be less to absorb the heat from lights. Also saves opening tent to make adjustments.
    The alien one I’ve got has a float valve to let the top up res fill up the system as the level drops.
    Gotta be nice and level as I’ve found out my pots are all I’ve the place sometimes and still add a few buckets of water here and there.

    See my thinking was having my header tank out of the direct spread of the lights which it can be with the space I hope to have. It won’t be that far from the chiller....if I had the header outside the tent then I’d have to try and maybe even warm the nutes up, if the header is inside and the chiller regulates it then it would be the easier of the two to control better ?

    I’m really considering maybe putting in some sort of auto top up from the res from outside the tent, that res can have the heater in and just regulate the tank itself and replenish the header when it needs to.

    I have an auto tip up on mine with a mini float valve doing the work.

    It’s fed from a 350l tank that’s kept topped up with a RODI filter on an auto shut off.

    I never water. It’s ace! Hahaha

    I’ve had one blockage at the end of one line of pots was a bastard to clear it out but been lucky so far.
    Kinda wishing I had the bigger pipework but it’s still going fine just need to tug a few roots back now and then
    Hope your all good mate

    Hay tobluey

    Just a quick question,, what tank heater have you got that actually can be submerged at bottom of tank.

    The ones i have at the moment can only submerge 3/4 way in top of water.?

    Ha ha are they only supposed to go so far down? I’ve got a 200w tank heater that’s sat fully on the bottom of a 100l tank

    Those lines on aquarium heaters are the minimum they can be submerged. Both the RDWC’s and the fish tank have fully submerged heaters.

    I just use aquarium heaters, they are sitting in the bottom of the epicenter. I don't heat the feed tank.
    You would struggle to heat a full system full of cold water so I tend to put warm water in to get to temperature on the initial fill then the aquarium heaters are able to hold the temperature. About £15 off ebay. I have 2 in the big flower system.

    I was going to have the epicentre in the room so the the chiller sorts the water temps out and then have the tank outseide the room to fill when needs be with the heater in

    I have my epicenter offset outside of the room. alongside the feed tank. The feed tank just drip feeds very slowly so no need to heat. I had a problem with the ballcock getting gunged up from feed tank to epicenter) so I may fit a filter from the tank to the ball cock. Its not a problem if you are checking every day but could be disastrous if you went on holiday.

    I don't see the point of having the epicenter inside the grow room if you have the space outside.

    I don't have a filter on the main line but have tied some fine netting curtain material around the epicenter inlet from the system it is easier to get to and does collect a lots of bits. Use about a sq ft of material and pull it into a bag so the water flows freely through the netting back into the epicenter.

Have the ends of the material hanging down it will really reduce the sound of the water falling back into the epicenter. Make sure you tie it really tight and secure as if it comes off it will float down the pipe work and block your system. I tie mine with string and an elastic band.

    Im tight in space with going for a bigger tent but that means the epicentre can just go in the tent to the side

    What’s humidity levels like when using dwc? Obviously I know the water is in the buckets and not that open to the air but does humidity rise just as much as say when you got soaking coco in a tent after feed?
