Beginner grow Aerokit

So, this little experiment is going ok too, there are 3 large girls in here already (3 weeks from seed) and a couple of little seedlings I planted just to make up the numbers, the aero kit holds 8, but after trying to do 9 in the other one I thought, less is more. The root system although slightly red (due to the nutrient solution I am guessing) as there is only that and water in the tank...would make sense uh, is looking really cool, it now sits in the upper tray of the aero kit as the hairs are so long now, about 300mm, but also the plants are looking healthy up top too, I have had to trim the largest of the fan leaves this week, they were getting ridiculously huge, when its the size of my hand I think it should come off, there are now plenty of upper fan leaves and I dont think this will stress the plant out too much, I am going to leave these in veg for another 3 weeks while the babies catch up, theres a couple of autoflwers just gone in and are now just getting established. Once they get big enough I will flip the lot again, I am now officially out of seeds, everything I have bought is now planted and tbh, I quite like the process from seed to plant rather than cloning and I aint got a grip of cloning yet or timing to clone, more research required..... watch this space....chiao for now.
