you cant do it properly without the ac except if you live in alaska or in a very cold spot year round a minisplit is easy to install, they even sell small 2kw now

yes the blocks need some dryback otherwise youll get algae

ok and how much ppm is the runoff

yes there is an issue what solution do you use to feed them, at what ph and ec you also need to measure the runoff, i bet it will be acidic

no venting need with minisplit just get some compressed carbon dioxyde

Exact Crop steering will only work when there is substantial amount of media to buffer the water content fluctuations With your method you better feed several times threw the day

I never said to ph the runoff Just not to reuse it 0.5mS tap is not "full of junk" It just contains some bicarbonates, which make it hard (calcium and maybe magnesium) Depending on you location you can also have some sodium and chloride (beneficial in moderate quantities) and sulfur Actually...

why do you need pool shock for coco? all you need is a balanced solution at 2.5-3.0mS and ph 6.0-6.5. then you turn on the pump and let it drip until you get 10-25% runoff. discard this runoff, it's only good for your yard At field capacity your substrate will be around 75% WC (water content)...

what kind of iron do you use

amnesia

yes

how much ppm reads the runoff

good method in my experience the bennies are pretty useless I prefer to save money for nutrients and run to waste. Plants will like a low EC anyways, 400ppm nutrients is usually plenty also, in my experience, doing 1 large watering of 15 minute (like cap) is inferior to watering 15 times a...

a dehumidifier is what you need not that crap

you must calculate the heat charge for all the apparels in the room (lights, fan, ballasts etc) multiply the total wattage by 3.4 to get the btu hot climate (during summer) will also influence the heat charge to dissipate

what do you mean

Here we have 230v current (with live and neutral) I think you are speaking about 120v right ? Because at 230volt, 600w equals 2.6 amp If we round this at 3amp, for 3x600watt it makes 9 ampere. In my experience it's OK for a 16 ampere breaker

wow a 15amp breaker per 600w you can put three 600w on this without issues

I think the voltage drop will be negligible To my knowledge these extension cord are very fire hazardous Ime it is wiser to use a single cable from the ballast to the bulb, without connection in between Even when I used lumatek digi I used to strip the c14 type plug to connect a domino I...

yes Sir 230v here, which makes 2.6amp at 600watt 1mm² wire is 18 awg if I'm not mistaken On the paper it's enough, but it's without taking account of the starting current of the ballast which is x times higher than 2.6 amp ?? So i'm wondering if the 18awg will suffice The price difference on...
