In larger grow rooms this requires a decent amount of equipment to pull off but in these small PC case grows it makes sense that something like a small yeast bottle and release should increase the CO2 in the confined space quickly and effectively making it worth it. I mention yeast because it cheap but a CO2 bottle or anything else would also work.
It wasn't the temps causing the issue. Everything was fine until I ran out of circulation capacity due to the canopy. At that point, the light hitting the leaves was just causing excess heat build-up in the tissues themselves because there was inadequate airflow to move cooler air in to keep the plants cool. Totally crispy plant.

If you follow my new journal in I think my bottom link in my sig, you'll see much better results.

Soon I will build a new case grow, with better ventilation. But right now, I just got my new NFT system (minus hydro fittings) and I need to get that set up. Only took FOUR MONTHS to get here!

SWC Micro Grow Member for years, finally deciding to post, with a starting project - a converted A/V Workstation case (larger than your typical PC case) into a growing box. It takes up just over one square foot of floor space, and I have about 1.5 cubic feet of growing space inside. I am using a 6-quart container modified into an SWC container for two plants. For ventilation, I have a 120mm computer fan powered by a 12VDC wall-wart from some random electronic equipment. I am using an over-sized air pump Rating: 5
