So I have fed them today with full strength veg nutes, I'll give it another week and I'm probably gonna a pull 3 of them.
I have moved the 3 I like to the front
Edit: I have also just bought a hlg 185h c1400b driver and a 100x165x35mm heat sink from tme. My 3 vero 29 3000ks are on there way from China. I should be flowering in the next few weeks. I have returned the other 300w vipar panel as I won't be using it and it was inside of 30 days
in total it has cost me £150 to build this vero light so same as the vipar panels and I'm pretty sure the results will speak for themselves
