Yeah well you keep that up and let me know what you have in 7-10 days.my 400w mh is only 25-30cm away from my tips, small fan and no probs
So so true, the mongo plants for some stupid ass reason always turn to out to yield the most in my own experience.Don't throw out the 'retards'. They can pick up awfully well later and put all into buds. They sometimes have the best result at the end of the day
Those heights youve recomended for 150w and 400w should really only be used as a rough guide, light height needs to be taken on a case to case basis, theres many factors, how many hours has the bulb been used for before, the ballasts output over time can change and decrease if magnetic ballast, heat extraction is another factor, theres no real set rules, you will need to judge for yourself based on some of the above factors.Your plant will grow out of this. There was actual physical damage to the seed. 150W...6-12 inches with reflective bonnet. 400w...12-20 inches with reflective bonnet. Growing mediums differ so use common sense.
ok, maybe 30cm would be ok if i was to get the temp controlled at under 30°C ?agreed (for once ) 30cm no issues
I have witnessed buds 5 and 6 inches from the thousand watt hps and still not get burned. Of course the buds were moved at first notice away from the lights. On the other hand I've been in other ops that suffered major bud burn because the plant moved to close to the light. I have never had a plant burn't by any lamp in any of the ops I,ve setup. I believe in having positive atmospheric pressure in my ops. This could be the reason. Slightly more air being brought in than is being vented. I fix my 1000w/hps bulb 4 feet above the gravel from the bottom of the bulb. I mount my bulb horizontally. The bottom of my bonnet is about 3 feet 8 inches from the top of my gravel. I stopped moving my bonnet up and down long time ago. I skirt my table(3ft x 3ft) with flouresent four foot tubes to cover any shadowed areas. The biggest reason that less than 80 degree temps are recommended is because after 80 degrees farenheit spidermites start to breed rapidly.ok, maybe 30cm would be ok if i was to get the temp controlled at under 30°C ?
I have a basic setup really. My temps are pretty easy to control because my tent is in the basement where it is only about 62 degrees most of the time. People always ask about lowering temps. It is not rocket science. The heat come from the light so if you cool the light your temps will go down. I will add a pic too.bigv1976, you still didn't explain how you manage the heat, which would be beneficial to Reject. And since we're showing off pics, here's some buds I grew that never saw the HPS closer than 16":
