Using the 600 might be the best thing to do, but there's probably nothing wrong with the 450 either. Why don't you discuss more of your soil and how you fert. People could learn from this.
That space is really too small because they might double in size in 3 weeks. This plant continues to grow in flowering.
polishpollack Reviewed by polishpollack on . is it worth changing my bulb? I'm running a 450 hps & have been since i turned to 12 / 12 (5 weeks ago). When i bought my kit (I'm a first timer) it came with a 600 dual spectrum. I had issues with high temps (90f - 100f) at the beginning so used cfls for veg stage. Since then i've improved my ventilation and temps are between 75f - 80f. Will the 600 watt dual spectrum bulb increase my potency / yield in these last 3 - 4 weeks? I've attached some images of the ladies, feedback of any type gladly recieved. Rating: 5
