thank you all for the answers!
Indeed i was hesitating bcz the bigger SF 4000 has two dimmers (that could more or less replace the adjusting of two smaller SF 2000.)
But yall gave me the kick to order two SF 2000.
Hope to become it soon so the next grow diary will be with them!
Thanks alot, apriciated your help!
Keep on growin' keep on lovin', because its all the same.
