    Default Wilma big 4 x Airpot mod x Migro 400 lights

    Evening all

    New here and soon to be starting my 3rd grow, just looking for a bit of advice on dialling in my setup before germinating

    So far i've a 120x120x200 tent, 5"extractor with carbon filter (connected to a temperature controller that also runs a small heater), migro 400 LED light and a wilma big 4 that i've started to mod as per one of the other threads on here

    Will be using 10 litre airpots and the standard MJ500 for the drippers, looking at an MJ1000 to use as a return pump to an external tank to create a waterfall for more D.O (will also be running a large air pump in the res)

    My questions are will i need a ballcock type system on the pipe from the external tank into the res? might have missed it but didn't see it mentioned in the plans in the other thread

    Also has anyone out there done a wilma/rdwc grow under LED's? I’m wondering whether i might need to look at heating the res slightly due to the lower running temps... i believe res temps of around 18c are ideal?

    Thanks in advance!

    Yeah I run a Wilma. I keep my res at 18 and have no problems at all to date. I use a tube heater for heat. I have mine in outhouse thing so not warm in uk at this time of year. Have it sitting 20-24 pretty constant now.

    What sort of mods have you done or is it fairly standard? Will be my first time using a Wilma so part of me is tempted to leave as is but the idea of the roots swimming around in the res sounds ideal.
    Do you run an external tank or just top up the res directly?

    Cheers

    Ta mate! Might look at doing a grow diary when I get up and running, seems like there’s a gold mine of info on here that would be great to tap into!

    Going shopping today, still scratching my head over this ballcock... the problem I’m foreseeing is that once the roots have dropped into the res and filled it out they will prevent the ballcock valve from closing? Has anyone run a system similar and found a way around this? Or am I overthinking and will the root mass not be dense enough to interfere? Help!

    I just run it standard really except I cut a square out under where pots go so the roots can get right into the tank. I could maybe see your point with the roots.

    Ta mate, not completely mental then! Better to be safe than soggy I suppose

    Do you run an air pump/stones then or are your girls ok without?

    Thinking I might make a box/cage to go around the ballcock and cover it in a filter sock to prevent the roots getting through, probably overkill but I’d rather not take any chances with the groom being on the first floor

    Yeah Iv got air stones in. Was advised to so I did. Just makes it so easy. Just fill it up. And just check the ec ph. Adjust if need be. Only thing is a pain is when the roots are big in tank for tryin to do a res change.

    Cool mate thanks for the help ??
    Yeah seems like a great system, ‘set and forget’, Mon the Wilma!
    Am used to keeping on top of e.c and p.h as I’ve only grown in coco, made a drip ring and auto irrigator for my last grow which worked pretty well but lost a lot of height due to needing a bucket to catch run off, will see if I can find a photo...

    Hey! I use a wilma xl with leds. I picked up an aquarium heater with a sensor to maintain warm enough water. I also have a heater in my grow room to maintain air temps

    Hope this helps. The aquarium heater was about £12 on amazon and works great... Has a temp dial to set it

    Cheers dude, was hoping to get away without heating the water but for £12 it’d be rude not to haha
