No worries :jointsmile:
Just goes to show, patience and diligence now saves a lot of money and headaches in the future. I too was in a hurry to start, and had to learn some things along the way. Now I want to buy new stuff...
If you were to invest in one thing, I'd make it ventilation. Look into a fan that has multiple speed settings, and strong enough to vent your growroom and cool the cooltube - the other investment... search for DIY cooltube on google and you can make one for half the price or so.
Good luck :thumbsup:
