If you want 1000 watt flowers you have to use 1000 watt lights.


I would have normally used 1000 watt lights during flowering. this time i used 600 watt lights for a couple reasons. My 1000 watt lights were old and needed to be replaced and i could not afford new ones. also i had discovered that the 1000 watt lights in my small room fried the plants to a nice brown crisp. However they were still 1000 watt big, just fried. You need a real high ceiling to use 1000 watt lights mine is not high enough and the lights end up to close to the plants.

this time i used the 600 watt bulbs for a total of 1200 watts in the room. I had to group the plants closer to the lights. i had way less light penetration. And much smaller flowers, about half the size of the 1000 watt lights. Still very nice just small, not as dense.

I am hoping to get new ballasts that will power 750 watt lights for next time. i figured why spend money on lights i know will burn my crop. save the money and buy something that will work as well and not burn the crop.

It is amazing how things grow under smaller lights. if you have a flat SOG canopy all the fruit close to the lights will be fine. If you try to flower full grown 7-8 ft tall plants under smaller lights the tops are fine everything else is small. You end up with a lot of shading because everything is put so close to the lights.

I am also discovering that moving the smaller lights can help with the light penetrating through the whole crop and allow you to spread them out for better air circulation. I you are using large or small lights leaving them stationary will eventually burn the plants directly under the lights.

I use a 1000 watt HPS with a light mover and keep it approx 1 1/2 ft from the tops with no light nor heat burn. My space for flower is 4x4x8. I have used a 600 watt HPS in the same place before I switched to a 1000. To be honest my flowers were not all that different, as far as taste & density it was still very good. Most of the bottoms I cut off anyways to let light get to the biggest of the buds. The best thing I ever did for my opp is buy a Lumatek switchable ballast & speed controllers for all of my fans. These help me control my temps in the summer & winter months with a flip of a switch or two. Best of luck friend.

Are the flowers really half the size? I didn't think moving from a 600 to a 1000 made that big of a difference on bud size.

In terms of output, it should be noted that a 600w is a little more efficient than a 1kW, meaning it outputs more lumens per watt (and also meaning less heat per watt.)

that is exactly what i plan on getting so i can use the 750 watt bulbs, with lights movers. the 1000 watt bulbs are just to hot for my room.

In terms of output, it should be noted that a 600w is a little more efficient than a 1kW, meaning it outputs more lumen's per watt (and also meaning less heat per watt.) Today 09:06 AMIn terms of output, it should be noted that a 600w is a little more efficient than a 1kW, meaning it outputs more lumen's per watt (and also meaning less heat per watt.)

yes the 600 watt puts out 88,000 lumins. the 750 watt has 105,000 lumins, the 1000 watt has 145,000 lumins.


Because i have a low ceiling in my room and can't properly separate the plants with the minimum 1 1/2 ft. i know the 1000 watt will burn, i have seen it do it. the 750 puts out more lumen's and lasts longer than the 600's. i plan to get the lumatek 1000 watt switchable to power the 750 watt bulbs with. also plan to build a counter balanced light mover, i have vaulted ceilings.

I will have no more light issues.

The 600 watt light just does not have the lumins to penitrate to the floor, or much futher than a couple feet everything below that level is smaller yes. quality is the same just not enough light to get though to the plants lower flowers to make them bigger like the 1000 watt bulbs do. when i would use the 1000 watt bulbs i would get larger flowers all through the plants; but the lights are to close to the plants and burned them. when using big lights you need at least 2ft between the lights and the top of your plantsor you will burn them.

i think 600s work better for SOG type grows...with smaller plants with less lower nugs, the 600s work perfectly. but if you are doing 10 gallon pots with 3-4 footers than yea the penetration sucks...lots of larf.

[TriWingGirl]

Absoloutly LOTS OF LARF FLOWERS. Very cool word larf.


Larf; Light, Airy, Fluffy

I have big fat flowers with 600's...but I dont try to flower 6-8 foot tall plants either...lol.. I never have airy buds...NEVER!..Airy buds are the worst, imo.... i have used 1000 and 600's, i cant tell a difference in my buds....But if I was growing out 9 foot tall plants, I would go with the 1000's....Thats a fucking tree....

Why don't you just keep the 600 and ADJUST your plant to your lights penetration.I have no prob pulling 1-1.25 zips dry per 30-36 inch plant and this is with a moderate yielding strain.With some spreading and tiein down i get about 1.50 zips dry with the same strain.

600's are good for SOG and that's about it.

I averaged around a pound per 600 with 16 plants in 10l pots (2week veg) 4x4 footprint makes it so0 much easier...

with 4 plants lst'ed in 10 gallon pots, 12oz was my best...probably about a qp of that was larf too...

I loved my 600's. I had 2 in my dr 150
