How's it going guys? Got some advice from you a couple months back but financial probs meant putting my plans on hold .

Anyways I've got my shit together again and ready to go but I'm having a problem keeping the temps down.

I'm running a 600w w/ cool tube in a 120x120 cm tent in my bedroom. I have a 220 m3/h pulling air through the carbon filter and pushing it through the cool tube and out of the tent to my window but I can't seem to keep temps below 29c. I also have a clip on fan blowing towards the light, temps were around 31c without it.

Anyone got any ideas what else I can do to lower temps a bit more?

Unless you get an air conditioner you'll just have to put up with it until the weather cools down. Even bigger exhaust and input fans won't really help because the air is still too warm so all you'll be doing is just moving warm air faster but it's still warm air.
You're not the only one struggling with temps this time of year.
What size in inches are your input and exhaust fans?

At a guess the 220m3/h is a 5" fan? for a 120x120 you want at least 6" minimum exhaust fan with minimum 5" intake AND some kind of fan moving air around inside the tent etc, this time of year also when the temps are higher may require an AC/Cooler etc just to kkep temps anywhere below 100 lol

I don't have an intake fan, just left the vents at the bottom open. Will a fan pulling air in help? The exhaust fan is a 5" RVK something or other from growell.

Also (confession time), I germed a few black domina seeds 2 days ago using the paper towel method. Checked this morning and they all had a good 5+mm root so i popped them into some biobizz light soil mixed with some perlite. When they break through the soil will they be ok under my 600w hps?

I know, I'm a dick for even thinking about starting them before I knew temps were good etc but I'm not the most patient of people and I die a little bit inside every time I have to go pay £20 for 2g so the quicker I can grow my own the better.

In these summer months not
having an intake just wont cut it im afraid, MINIMUM u need for this weather/temps is 6" exhaust, 5" inlet(from ether a cooled room or in conjunction with an AC) in a 120x120 n even then you will struggle etc

I'm up in Scotland so never really considered that the weather would cause high temps in my tent lmao. How bad is 29c? Is it a straight up no chance or could they survive? Could it even drop to a more acceptable temp when the weather cools down again? I know it's far from ideal just wondering how much I can wing it with my first grow.

I got a complete setup and the fan, ducting etc is all 5", will I need to get 6" ducting and a 6" cool tube to go with the fan or is there some sort of adaptor I could get to go from 6" fan to the 5"

Also I'm definitely taking on board all the advice and not just gonna do whatever I want regardless (like I've seen many on here do). I appreciate you taking the time to give me some advice.

Its as "bad" as your skill level etc, if you know how to adjust for ups/downs in temps. adjust light distances, water/feed properly etc you should be fine etc

Right before we start with fans n the etc, what size carbon filter you running? also what size are the vents/holes etc on your cooltube?

It's extraction kit 2 on that page. It came as part of the bay6 xl complete setup on the same website. The cooltube was just a cheap 5" one from amazon. I know it's probably shit but I figured it would all last a grow or 2 and I could sell a bit the finished product off to upgrade to some better quality equipment.
