Theres a few things you may wanna consider...
Cooling and ceiling height: most people wouldnt do 1000w hps with less than 8 feet ceilings. Hard to not fry the plants. Especially if youre drawing air from inside at 74-77 °. Ok you got an aircooled hood, you can maybe draw air from outside to cool it and make up for this partially. But the hood will also eat up som height inside. What height is your plants when you flip from veg to flower? Have they got space to double or tripple in size?
Tim here is showing some lovely plants and yes you can vegg with MH and HPS, especially super hps with whiteish spectrum. But theres a few things to have in mind. First of all stretch will depend on many things. You see how nice and bushy his plants are? They arent touching, leave to leave, and thus dont feel that they compete over light. When they do this its a different story, especially if they have other factors of stretch (IR, far red, low light conditions, high heat), they might bolt, and when one stretches they all stretch.
So veging with 600 will actually keep your plants shorter than a 400. Low intensity, they look for the light. Blue for vegg: led users vegg bushes with as low as 3000k, which only has about 12 % blue. As for HPS spectrum being bluer at 3 feet than 1.5, i dont really give any credit to that, all respect to Tim, but i think its more on planetary distances. Also, vegging 4x4 with 1000w hps and low clearance sounds like a bad idea to me, maybe for the last week before flipp ok, but during seedling stage id iay nono.
Its more about how you do it, keeping plants separate, keeping the right environment, good idea to vegg for a week with whatever is your final light before you flipp so they are used to light youll gice them. Remember that plants from seed needs to be mature enough before flowering, no matter how big youve youve vegged them.
When i see youre way of reasoning it reminds me of myself a few years ago, the same inquisitive mind setting out to read up on forums to prepare for the first ambitious grow. However there are so many things about growing that youll only learn about thru practice.
My suggestions to you is this: do a test run first. Maybe 12 plants or so, that way you have maybe 9 left after the first one dies on you, or for removing the small runty ones. Use some cheap but stable seeds. Try out some plant training before you go full mainlining. Use soil, less effort to ph. If u wanna use your own compost, try a few variants of mixing in aireation. Get yourself comfortable with watering; overwatering is the first typical misstake. As you grow, read up on VPD and remember the tables will be very different for hps and led, due to different leaf temprature. That will get you covered as far as environment, as long as you can control temp drop and humidity spike at lights off.
A test grow will also see if youre likely to get buggs. Or PM.
If you have fresh worm compost, brew some compost teas and try it out.
While your doing this setup a vegg tent and start your mainlining. But get some ordinary growing skills, the practical bit, as well first. Otherwise you are liekly to vegg and mainline your plants for a few months and then either have burnt or pm plants after a short while in flower. See the whole cycle out before getting advanced.

those are lovely man, can’t wait to get mine running here. I’ve got a ways to go. I’ve got pretty much everything for my tents, just need a few more pieces and small things before the setup is complete.
