FF4 by FastBuds

So I have received some seeds from FastBuds to test all part of the FF range and have left them in a glass of water till the roots sprouted, once sprouted I put them in a probogator with BioBizz light mix soil, once they sprouted through the soil and seemed sturdy enough iv moved to a grow tent, on a 24 hour light cycle feeding just small amounts of water with a spray bottle, nice and healthy, leaves a bit browned from were the shell of seeds were stuck on 3 of them but all good. Not sure what strain they are as they are tester seeds.
