I would hit them with a nice dose of veg nutes the first week of 12-12 and think about adding Liquid Karma and some CalMag to the tool bag for any defs IMO. For a possible table/tray, go to Lowes or HD and check out the cement mixing tubs. When I was there the other day they had some that were low profile, maybe 7 to 8 inches high and 2x2, give or take and they were all black, also they are only $10 or less. I have a 6 bulb rack of those same lights , like them as well.
As for me, I am doing quite a bit in my imaginary world. I am going threw a coco coir fascination right now, it seems like coco can be as quick and robust as hydro without the reservoir tempeture issues or water pump accessories. You will probably see me posting about it here and there since I have about 5 going right now in the coco in different stages and even have a couple side by side with soil, coco and DWC to see who will do what. On top of that I have some other DWC stuff along with about 2 dozen in the flower room and about another 2 dozen in the veg/clone/mother cab lining up to do there thing. It is really helter skelter in my grows right now because I am just doing allot of experimenting with different mediums, strains, veg times and so on. I am even burning up some plants to see how leaf burn relates to yield because alot of people freak out when they see nute burn and just don't understand that the leaves may not be able to handle the nutes, but the flowers/buds can and may do better in spite of the leaf burn. So I am not really able to dial in my grow for one specific system or strain, but in the next few months I should have my stable sorted out and just start working on some power grows where robust healthy plants and good yield are the main focus.
