1000watt vs 400watt?

[mrgreengrower]

Ok so I don't know, and need some help will a 1000 watt hps light produce more fuller buds then a 400w or is it only for space ? I grow now with a 400 watt hps and really only grow 2 to 4 plants at a time but I was wondering will a 1000 watt light give be a better, fuller, bigger yield or just the ability of flower more plants at one time? Also will I really be able tootell the diff? And heating how much hotter will a 1000w light be vs my 400 ? Sorry I know a lot of ?

if you can keep your grow area cooled, a 1000 is well worth it.

Every lamp has it's "growth zone," which is the distance away that its light will support healthy plant growth, minus the minimum distance the plants need to be from the bulb. Here's a graph illustrating the strength of different wattage lamps at various distances.



As you can see, a 150w bulb that is 5" from the plants creates about the same intensity of light as a 1000w that is 15" away. It should also be noted that on this graph the maximum light intensity the average pot plant can handle is at about the 170% level. All of these bulbs can make more light than the plants can handle if they are close enough, regardless of heat management. So the answer to at least one of your questions is that all of the wattages shown (and more) can create cola tops that are just as frosty if a plant is grown directly underneath without rotation. However, the higher wattage lamps will create this level of crystal further from the bulb, making a larger area of maximum growth within which the plants can be moved around without significant detriment to trichome production.

Edit: The minimum amount of light in the graph that supports healthy growth is about 15%.

wow thanks i guess think i might be a little too messed up to under stand all that but i thank you, sounds like i should stay with what i got i think my head hurts

why didnt u mention a 600w?? those are the best lights..by best i mean they give u the most lumens per watt..but yea its all about HPS thats what gives u dense bud..lumens will give u more bud..so if u did a side by side yes a 1000w would probably have fuller buds with more bud spots but they wont be much denser then a 600w or 400w if grown properly.

i dont know i thought i already have a 400w whats the diff between 400 and 600 i thought thats not a good jump or change i thought that 400 to 1000 is a better jump or change but we can throw 600 in there too. i am just wondering if i will notice and is it a waste of money or not?

i like 1000w and 600w the best but i like cheap bills to so i use my 400w lol and i get dense buds..maybe u should feed your plant a ripener additive if your having "dense bud" issues..or put ur light closer to the buds when your in full flower

well this is my 2nd grow, my first grow was bag seed that i didnt really care for so im working with a little northern light now and only a couple weeks into flowering so not too sure about none dense buds as this plants now are amazing and 100% diff then my first grow so will see if bud density is a problem but i dont thing thats a big deal just want too make my girls happy

 

[Cali.Grown>408]

there looking happy to me..but yea i got a 1000w, 600w, and 400w but right now im just growing in a 3x3x7 space and 4plants so my 400w was the best light for that job..if i had like 4x4x7 and 6plants growing i would use my 600w and if i had a little more space and like 10 or more plants i would either use my 1000w or combine my 600w and 400w to spread the light out better.

I think the 1000 would only produce bigger buds thn the 400 when dealing with larger plants because the light can penetrate deeper, but if your canopy is dense it probably won't be as helpful because the efficiency isn't that much greater than the 400. I think your right it's just going to cover a larger area. A 600 however is more efficient per watt. A 1000 watter is gong to put out way more heat than a 400, especially in an enclosed area.
