Well I think either your watts are off or your lumens.....HPS 1000w put out 140,000 lu and 400w MH put out 37,000 lu.....So, that is way too much light and HEAT in that little of space! CFL's or floros would be good in that veg chamber and a 400w HPS for flower. Or perhaps you have the wattage off...?

Instead of pruning look up LST. Basically tying and training the plant. Or you could flower once they reach 6 nodes, that way they don't get too big.


Bree don't know hydro, so I can't comment on any of that.
