hmm, ok. I thought the cabinet with the series cooltube was going to be for MHs and vegging, sorry for the confusion.

You're probably going to be vegging each plant to be flowered for about 2 weeks and will have to find some space for them for that period.

Your wish for a monthly harvest means you'll do cuttings once a month; those will take about 10-12 days before they're ready to go under big lights to veg for 2 weeks and then on to the flowering area, where you will be taking out the same number of plants as you put in.

A sample sked could be to take cuttings on the 2nd-3rd day of the month, to be rooted & ready for veg on the 12th-15th, then vegged until the 30th, when they can go in to flower and mature plants can be harvested.

Keep in mind that the harvesting job is the most time intensive and tedious part of the whole gig. I elected to harvest every 2 weeks to break up the job a bit. I initially was harvesting 2 trays at a time 1x/month but manicuring 46 plants and having 46 more to go in at the same time was just too much work in one go.

You'll have fewer rootballs, but there's every reason to think that you will get just as many buds and as much weight as I do. It'll be a very big job once a month.
