After a successful first bagseed grow in soil and perlite under cfls i progress to my second grow.

This time a Wilma 4 Pot Hydroponic Flood and Drain system with a 600 watt HPS in clay pebbles. Seeds = Blueberry.

So, the problem is that I have a limited grow space of 75x75x200 so I have room to buy the BudBox Medium Grow Tent.

Would it be recommended to put a 600 watt HPS in this tent as it says on the description "400W is possible but make sure you have good extraction"

If it is what sort of ventilation am I looking at for such a system with plants like Blueberry.

Also would you advise 4 plants at once in there

Thanks in advance.
