Starting a shed grow

So I've been growing indoors for the last ten years in a tent

I'm in the prices of building a shed 20x7 ft

I'm going to get it close cell spray foam insulated (floor cleaning and walls) and wired up for power

The plan also is to build a veg and flower area with a partition wall between the entrance and grow area

I have an thermostatic heater for night time cooler temps because living in Ireland it's not to warm to be honest.

I have a rhino fan/temp controller and big ass carbon filter combo.

My question is there any thing else I need to thinthink of ?

Veg is a cfl set up
Flower is a 600watt citizen DIY rug with a se 600hps added in for the Craic
Flower will be run using autopots because of the say and set and forget ness. With 250litre res

Sounds like you've got everything covered except humidity. You'll need to keep an eye on it. Cooler temperatures are, by their nature, drier. Add the lights and heater to that and the air can dry out in RECORD time.

You might have to add a small humidifier to the mix to keep your RH up to 45% or so, but that's about the only thing I can think of that you haven't addressed.

Thanks tacomac

I eBay something with a humidistat I didn't think the air would dry out because it always rains here and I will be pulling out side air through a DIY box with car panel filter to keep the bugs out

In that case, you may be fine. Just wait 'till you get up and running and monitor the RH. If it's constantly lower than 45%, then you'll need to order one in. Dipping down blow 45% only once in a while isn't going to hurt anything at all. You just don't want it down there all the time.

You'll have to see what humidity is like but even in a wet climate if it's cold you still may require one. If your spray foaming then you should just go sealed imo. Yes it does mean running CO2 but you control all aspects of the grow ;).

No Co2 for now just outside air being draw in through a big ass car panel filter

Would it be a waste of time to get a u sterilizer to kill any bad stuff coming in or will that create ozone gas ?

If you mean a UV light, I would say a hepa would be better IMO to filter the incoming air, also a uv light does not create ozone that I'm aware of. The effective range of uv is inches so it's more of an over time type of system. I use a hepa in my shed to filter the circulating air but only because I had one on hand. I'm in a seriously cold area and if I bring in outdoor air I need to heat the room, one of the reasons I still run HID lighting

Cool bean thank u I'll eBay a large hepa filter and build a box for it and run my intake ducting from it

Almost finished laying my bed of hard core. Two tons to cover a 20 x 7.5 area Jesus that's loads of work with a shovel and wheel borrow

Took clones last night for my next round

I'll order the shed on Monday so that means it should be delivered two days later then I have to organise the insulation company and an electrician

I'll be running cobs and hps

Do u think I'm better off mono croping or making to 600 watt rooms and harvesting every 1.5 months ?

For cash? Three light rotation. @16mins. But recommend the whole 30 min vid.
