First time sea of green suggestions

So to start i used a room in my brothers rented house last year for a perpetual grow that went pretty well. The landlord started freaking him out so we shut down. I had a 400w mh for the veg side and a 400w hps on the flower side. I let the plants each veg for about a month before flowering, sometimes longer. We were harvesting 2 plants every 4 weeks. The plants ended the up getting fairly tall, therefore i believe i was just wasting grow energy because anything on the bottom ⅓ of the plant was pathetic. He just bought a house so we're starting a sea of green. I bought one more 400w mh and another 400w hps. I will have 5 mother plants to start. I am using 7"x7" square pots with organic soil. I'm expecting to only veg for one week making for some extremely low plants. I want to cut 5 clones every week, meaning if i flower for 12 weeks, I'll have 60 plants under my 2 400 w hps lights in a 4' x 8' area. My question is this : will my 5 mothers be able to keep up with one clone every week off of each plant?

That sounds fine to me. I cut 60 large clones off 3 mums that are under a 200w mh. I only use 30 clones a month, but sadly some dont make it ( I'm not the worlds best cloner...lol) I usually want to keep a few clones for new mums and I like to choose the best looking ones to go into flower. The rest get dumped or given away,unless its spring then I sell them.
As clones are the life blood of a perpetual grow op. Take more then you need,better to have more then not enough. I think you said your going to have 4 lights now. 2-400w mh & 2-400w hps? the one mh would be enough for the 5 mums if ther not trees..lol, then you could use the other 3 lights in flower room and really pump out the buds. I would rater use my lights growing bud then clones. You could veg in mum room,as you wont veg long in sog 0-10days veg just to get good roots b4 flowering.

30 plants under 400 watts?.. seems like you would want at least 1000 watt per 30 plants?.. check al b. fuct if you havent already.
