Nothing wrong with those fans you have.
He pictured a duct booster, which is inline but not the same as your fans.
Filter stopping negative pressure

plug those straight into the wall and see how it goes. They should be BLOWING LIKE FUCKING MAD when wired straight into a wall. Maybe the blower is going.
Thank fuck for that Haha yeh they do blow like fuck almost take your breath away it’s just when connected to that filter. I’m sure there is a shop nearby I can pick one up from if not I’ll look at those recommendations I’m not making one I can’t be bothered pissing about with charcoal

i made one many years ago and yeah it was a pain in the but. This was before amazon was a big thing and finding things online was a little more difficult. Now they have them for 50$ and that is crazy if you ask me.
Original problem was definitely shitty filter
New filter turned up today had to go for the 6” rhino hobby as opposed to the pro as a temporary measure because cash is...gone haha should sort me for a bit
Tent is now setup as below
600w hps
Filter-6” fan-ducting-hood-ducting-out of room-vented into house
4” fan pulling air from outside into base of tent
No problems with negative pressure at all
Temps after 2 hours currently sat at
Room: 21.5/70.7f
Tent Bottom: 27c/80.6f
Tent Mid: 28c/82.4f
Tent Top: 27c/80.6f
I expect temps to drop slightly through the night but the temps are lower then they were with the old filter
Would you be happy with those temps veg through flower?
Obviously I can go back to 400w (havnt checked those temps but I was curious with 600)

Are you thinking of inline booster fans or something? Inline fans like his vortex are far superior to blowers for dealing with ductwork and loads like carbon scrubbers...
Originally he thought due to high temps and the fact iv never done this before that I may of been referring to booster fans.all got cleared up though

yeah i didn't know they called everything an inline fan now. Thought only those boosters were inline fans. We cleared up the confusion earlier.

Do you have much in the way of air circulation? It doesn't cool but it does mix the air to give a more uniform temp from top to bottom.
Don't forget to only take readings in shade and not in direct light, the HPS spectrum will give a false reading with al the IR.

I have two 6” 16w Secret Jardin clip on fans iv been using both An infra red temperature sensor and a humidity/temp sensor in the tent
I moved that last night out of the light still at canopy height just nearer the door of the tent temps were awesome through the night 23.5-24c/74 75.2
Iv also changed lights on/off time slightly so hopefully that helps too

Yeah I used those lumii bulbs before. Not very good in comparison to Philips. Osram are good.
A good bulb on a budget are the omega bulbs which have a similar output to Philips but a fraction of the cost.
I doubt the bulb would change the temp of a room unless it was a super red spectrum in comparison to dual spec.
The wattage will depend on the ballast and there is some major variation between one ballast and another even in the same brand.
Especially in the cheap ballast market.
I wouldn't use dual spec for flowering. Its a lazy mans bulb.
I’m definitely changing the bulbs for the first properly done grow,this all started because the mrs planted a seed under a small 40w bulb that we had left over from the reptiles we kept.iv been thinking about it for years I just wish I’d of bought decent equipment to start with then I wouldn’t of ended up with
2 tents and all the extra shit i don’t need haha
I’m definitely not lazy I go a bit ocd with things like this
Grow medium is one I want to sort myself also, not keen on stuff just done for me I want to get this as perfect as I can so I know exactly what needs altering and when I’m not growing for myself to end up with shitty street quality it needs to be done right
