You can build your own flipper for about the price of a 240v timer, and use this design for other applications. e.g. converting a 120v timer to a 240v timer.
Parts:
120v timer
Potter & BrumfieldKUP-14A15-120 relay & socket (doesn't have to be this make but P&B is common and reliable)
cord...
when did you start using the 400w? Temps? Nute break down (ratio, micro, bloom, etc)
I use very similar nutes, but i use a 600w mh. Your pics look roughly where i would be at around 3 weeks in flower.
Anyone getting sick of the same questions being asked over and over?
It is almost every day people asking how to sex a plant, when to harvest, how to clone, method for this method for that. I have not been here that long and find it a waste of time to be sifting through the same bs all the time.
