Oh, no. I was talking about the 6500 in the 4x4. In appropriate size tent will basically be same thing. Yes as to becoming back ups. Thats how I got the ones (LEDS) I have. Started with 3 100 watt quantum panels in 2x4. Then the SP 300 in there, 100 watt panels temporarily not needed. Already had 4x4 with 600 watt HPS, wanted to try LEDs. First led grow good bought another SP3000 and another 2x4 all on sale too good to pass.
Got tired fighting heat of hps, bought another SP3000 on sale plus discount code. put new SP3000 in 4x4 and snatched another SP3000 out of one of the 2x4 tents and put the 3 100 watt panels back in there in there. 3 panel led tent is moms.
This worked very well. So, on big sale and discount code I got the FC-E6500, impressed with what gmo was doing with his light. Again removed 100 watt panels, Sp-3000 back in there, one SP-3000 not used.
That, is when the 6500s power supply failed. Removed light put the unused SP3000 in there and again took another SP3000 out of a 2x4, replaced with two of the 3 100 watt panels for the moms.
So, yep, keep and reuse! I can supply myself with a 2x4, but it runs constant. I have Built up a supply this summer that will keep me in bud, rosin and hash for a minute. No more 3 tents mess, no need. Too much work. I dont need to run a constant flower 4x4 and feed it. So. One 2x4 is going to be run part time, for veg if no room in moms 2x4, or if not running moms tent at time. 4x4 will be flower tent. I am liking clones better than seeds, everything is same, height etc. The extra tent will let me raise select clones on plants from seeds.
For seed 20Twenty Mendicino, for one does list a percentage of "variability" a particular strain of theirs has. Snocaine, glue sniffer, and most others from them havevery slight phenotype variation. Some others? 5 seeds look like 5 different plants. I dont have the time to sort that mess out.
