I'm growing a critical + 2.0 from dinafem and it seems kinda small for 2 weeks old. I'm using a 600watt MH bulb, and I keep it about 30 inches from the plant for 24hrs. The temp is always around 75F and humidity is always between 50% and 60%. I always wait till the top inch of soil is dry before I water, which is about every 2 days. Any input would be great.
