LSD Small Tent LED

Overall, progress is feeling a bit slow but I know in a couple of weeks it'll grow a lot more! Increased my humidity slightly as it was quite low at around 30%. Got it up to 40%. I'm feeding it half a litre of water every 3 days. I feel like I should up the dosage of water but not quite sure yet as the soil still seems slightly wet after 3 days. Still deciding what to name the plant ;) I managed to fix some ventilation issues I was having. I'd wake up to the lil one having an atmospheric temp of 31 degrees. Managed to get this down to 22-24 degrees celcius, but now my humidity has taken a massive hit (down to ~25% from ~40%). The noise of the set up has also slightly increased, so in order to stealth this grow I may have to make some sacrifices in some areas to stealth the set up slightly more. I think my next grow I'm going to switch to CFLs because of the reduction in noise. If anyone has any ideas of how I can quite the noise please let me know. I've tried using sound dampers and it's slightly helped but it's blocking my IN vent.
