yea ideally 6500k then 2700k but tbh only using 2700k isnt going to do harm you'l just end up with slightly shorter more bushy plants which may be better if space is an issue
blue 6500k for veg, red 2700k for flower 400w is easily enough for 4-6 plants
tbh as your only growing smaller plants id say a 250w cfl would be enough and be able to get good yeild
stay well away from shortrider if you want an autoflower return that shit and buy something else i can recommend afghan kush ryder and la diva instead both of them auto flowered unlike shitty shortrider
yeah i also had shortriders and a mix of 3 other autos and the shortriders were the only ones that didn't auto so in the end they got ripped out and binned as they were getting in the way of the others
looking good there're startin to get bigger and nice dark green aswel thats what ive noticed with leds they always seem a really healthy looking colour whereas somtimes under traditional lights you somtimes get a very pale leaf, unless anyone else has seen that with leds?
btw that particular bulb is for flower look for a 6500k for veg stage and they can just be swapped when needed and they also have 105 watters still on e27 fixture

somthing like that for a light as its a standard fitting not e40 which would mean buying...
yea i agree with that if you have the floor space for pots and the space in midair for a lamp you can fit a tent its not lik you using the space between the lamp and the plant for storage is it.. just buy/build a small one
90w will not get you the results of a 400 at all, i mean im all for leds iv got some myself but dont believe hype like that more like the results of a 150w or roughly around that area
leds can get results but atm they will not be as good as hid lighting, but if led is the only practical option then go for it you will get buds but not a massive amount, id also go with dwarf autos in your situation
maybe if you put a link so people could actually see it..
also square pots would be better as there isnt wasted space you get with circles especially as you say space is limited
