a lot to concider…room temps size of veg clone area…
personally for micro grow setups i like simple compact flouro 23 watt cfls but they seem to be dieing in popularity in hardware tores here im not sure about everywhere…
the new leds in hardware shops seem to be taking over in sales but i have not tried any for growing seeds or clones.Im sure people on here can help as my info may be too old…
one 23 watt cfl can sprout a 1.5 by 1.5 area full of clones and seeds then one cfl for each seedling in veg… 1 can actually suit 2-4 seedlings or semi vegging plants in solo cups for a while too if needed room…
the best for veg though is 125 watt or 250 watt cfls for faster growth with bigger pots …too little lumens in veg can stunt growth and if going perpetual which it seems like u might, the new vegged planted might not match the flower room after last harvest…lining it all up is a task that takes time to get used to each setup…
people on here can probably help you master lining up all the right lights and timing for seed clones and veg and flower though if perpetual is your thing.
as for metal halides in veg good for cold temps and good growth (cool temps= 600 hps/mh less power than 2400 watt heaters)but power wise in no too cool areas to hot areas leds will be best or cfls or (if hardware store leds have right blue or cool white spectrum) they might be best…metal halides were also sometimes used by older school growers wanting more resin/trichomes…5000k spectrum seems like it worked best 10 000k not so much…others wanted yeild so went with HPS which was well known as flowering spectrm but both work…cooler temps or cool basements…they work well…bigger buds too but imo not as dense as good led grown buds…600watt HIDs were the most efficient to watt…other HIDS came out like ceramic and read good things but never tried myself…
if going with HIDs choose watts for size of area one 400 watt will veg 4x4 from memory and flower 3x3ft…and again HIDs ie mh/hps or ceramic whatevers use less power to heat a room than a heater.digital ballasts can do both mh or hps but hydro shops i worked for all agreed they were not as good as old school magnetic ballasts…this is all old info though…
