The Mystery Gang

Hi guys, So this was the first week in to my second grow after germination. Some upgrades form the start of the last grow; Intake fan upgraded, I have no idea of the power as it is ot listed on the unit. It's an industrial mini intake fan acquired from my old mans place of work. Shh. I now have the weaker fan I was using that caused the water build up in the ducting as an intake just pulling fresh air in from the room (open window above the intake). Finally, experince upgraded! ;) Hopefully with what I have learned over the last 3 months this is an even better experince. So, I Planted on the 22nd so these girls are now 10 days old. 3 days later all 4 had popped with the shells still attached to all 4. This worried me a little but I left them a day or so and they were loose enough to literally glide off with the tip of my little finger. I have uploaded a video for the 25th. I know I dont have no pot bottoms at the moment. Whilst I am not watering heavily I'm cool lol need to pop and buy a 4th this week. They're now all at a similar height and look good as you can see :) Last pics were taken on the 1st of May. Watering with plain tap water in small amounts every few days once I see the top soil start to dry out slightly. Humidity is kept stable between 65 and 70 at the moment and the heat is sitting between 20 to 22 in the day. Really looking forward to this grow. I am a little worried that not knowing what the strains are will start to get a little tiresome so if anyone has any educated guesses along the way please comment lol.
