I have a switchable ballast so getting a halide to go with the hps hort eye for flower <and veg at the moment> already have would be no big deal .I just dont want to waste the cash if im not gonna see much gain in the veg cycle with a metal halide as opposed to trying to veg with the hps .This is my first grow ive done about 100 hours of reading and im basically learning the ropes already made alot of mistakes, i know ive had some transplant shock and a lack of nitrogen and of corse like all noobs im sure ive over watered i guess this could could explain the short height and very small plants <this is shwag seed > so im kinda going at it blind on strain .thanx again in advance for tips folks.
