New Grower Adapting loft from winter to summer set up

[MrAmnesia]

I've got a well insulated groom in an uninsulated loft , currently run one 600w bulb , intakes via two 4inch fans suck in in the air from the loft both in low setting at around 100cfm each , extraction I've got a 6" which can run upto 600cfm which extracts through a hole directly into spare cupboard , now last summer whilst building the room the temps in the loft were in bare able , so plan is to swap things around , I'm going to intake from the spare cupboard with 6" and then I was thinking of extracting into the loft with the two 4" or possibly upgrading to a 8" , will it be safe police wise to extract directly back into the loft space? , think it was near 25-30C up there last summer I'm hoping with this set up I should be able to keep the temps down inside the groom itself

Well just crawled right to the edges of the loft where i was hoping to intake , where the eaves are theres brick on top with three holes in each running all the way along , tried pulling one but they feel like there all connected any ideas?
Can see small bit of daylight coming from beneath the brick work

I got an idea. Switch to LED. Save on electricity and heat.
Need heat in the winter switch back.

I'm 100% led, so it sounds good.

You can try run your lights 18/6 with lights off 12-6 pm during summer...

I run 2 tents in my loft. Insulation you e already taken care of. The way I run my vent 1 supply fan and 1 extract split etween the 2 tents. I pull my supply air from inside the ouse and vent the extract into the loft. I have previously had the supply from inside the loft and from outside under the eaves.

My current set up gives the best year round stability, the temp inside the house is 90% more favourable than outside, running the extract into the loft space also has a buffering effect on your heat gains/losses. In summer it can help keep it a bit cooler when your roof is being a storage heater. I run led and in winter have to supplement the tents with a bit of heating.

My intake is a hole punched in the airing cupboard ceiling.

it is isn't it?

Yeah my current extracts a hole punched in airing cupboard ceiling , would it be safe to extract into unisulated loft police wise? If the lofts 25-30C and im pumping out extraction at similar temps in theory I should be fine

Venting into the house makes the house stink, when you go in and out of the house you are venting that smell at street level. Venting into the loft makes the smell travel further.

The real tell tail is when it snows. I have less snow on my roof than my neighbors, so for 2 days a year that's an issue. Gonna insulate the roof with spray foam this summer.

The filth would need to suspect you have a big old operation going to look for way TBH. Domestic property grows that they are on the look out for are most likely whole house set ups. I would imagine a quick look at your home from the trained eye would show you are actually living in it, that would lead them to think it's a personal grow and not really worth wasting their over stretched resources on, depending on where you live of course.

The helicopters look for localised hot spots I think. Patterns that give a grow light signature. A hot roof all over doesn't flag up too much.
