Id have to get bulb holders etc.. all money ! Annoyed that I have a spare led tile but its on the blink, can turn it on and sometimes it works.. other times it cuts out as soon as you turn it on and makes a bit of a fizz :S
Bit the bullet and cut 2 of the same plant.. its one of my better plants that are under the led tile back right, it had the most growth to take cuts, I just hope they survive, they were cut then scraped a little with a scalpel before dipping in root powder and planted in a propagator and left on...
What ever your going to do please separate it asap, I wouldn't want to see them both go to seed.. all it takes is to miss one or two pods and its game over
I like the idea and have thought about doing that my self, a lot run 1000w HPS so your only 200 over them.. the t5 units I would maybe only light 3 sides leaving one side for easier access and maybe downsize the sides to 3ft units ? With the right spectrum bulbs it would be fine
