ive used the bio bizz range quite alot but never bothered with the top max, usually went with shooting powder or pk 13/14 but tbh theres not a huge difference with them all in my experience( some of the other lads are more clued up on that kinda stuff) but goin by your bulb size its gonna take at least 8 weeks veg to pull that kinda weight....this is all semi-educated guess work of course , i dont know the strain so im kinda shooting in the dark, but i do know the nutes, medium and bulb. first off get them under the big bulb, stick the veg lamp in beside them if you can though but your gonna need hid lighting as fast as possible. the bonus with bio bizz is its bloody hard to overfeed and fry them( not impossible though, trust me ive fuckin manged it!!! still dunno how the fuck i done it though!) so you can chuck feed at them . i still think your lookin at 8 weeks veg......you'd be much better off with a 600 hps ballast mate. or even better a second 400.
the 400wt is great i had 5 autos under it each gave me 4+ just trying to get same result with reg fem seeds . Yh bio products r great nether had no probs with them and always gt some nice tasty bud i did a hydro in a wilma system before using advanced nutes quantity was gd but quaility wasnt taste wise, hense the switch bck to bio products i thrown in pics of blue mystic 5 weeks veg showing first preflowers i overwatered a little hence the leafs curling a bit on one
lmfao!!
