Critical Orange Punch - 1st grow

Started a fifth seed in water. As of today, I have 4/5 seeds germinated and in 1l airports. I hope the final seed will catch up with the rest as it’s about a week behind. I’ve been struggling to control the temperature without having the extractor on a super high setting. I added some ducting to vent in from a cooler room - this helped keep the temperature at a steady 27C with fan speed on 4. I was struggling to keep it below 29C before this. My timer arrived so I’ve switched from 24-0 to 18-6. This has also helped with temperature control and will hopefully cut down on electricity which is around £3 a day. I’ll probably try 24-0 for the next grow. I’m going away for three days. I’ve lowered the light from 50cm above the plants to 35cm and lowered the intensity from 100% to 40%. I’ve left the plant pots in a saucer with 4l or so of water. Not sure if this was sensible but hopefully the plants will survive until I come back.
