I started iff with CFLs but i hear you get way better yield using better lights. can someone tell me how man plants i can grow under a 400W light and get the most yield??
I believe thats also correct.I have found that 4 plants during flower is about the max for a 400w unless they are tiny plants.
it depends on the size and strain of the plants, and whether you are flowering or vegging.i have 10 under my 400 watt but im also going to add 8 more plants and one more 400 watter but i just started this setup so no results to give u on it
your wasting light. 4?????????I have found that 4 plants during flower is about the max for a 400w unless they are tiny plants.
I suppose it would depend on your hood type and floorspace. But I have a 400w and I can tell you that I have vegged up to 12 plants with it up to 1 ft or a little less, but in flower I have found that unless I were to lollipop them or something, that 4 plants seems to be the max number of 3 footers that I can put in there without some of the plants not getting full light. These 4 plants take up a footprint of about 2.5 x 2.5 feet which is about the max for a 400w no?your wasting light. 4?????????
hood and distance is most important..... and i believe a 400 watter is good for 4 x 4 if used properly.I suppose it would depend on your hood type and floorspace.

distance aint the prob. heat, just blow the heat away. SEE EVERYTHING IS FINE 1000WTT HPS no hood vent see were they R. NO BURNED BUDS A HEAD OF TIME.hood and distance is most important..... and i believe a 400 watter is good for 4 x 4 if used properly.
i wasen't saying it needs to be FAR away... i keep mine as close as possible.... i was saying distance in reference to lumen output..... the further away the less lumens.....distance aint the prob. heat, just blow the heat away.

i can read a book on how to grow tomatoes.... but cherry tomatoes and jumbo tomates are quite differen't...... guidelines are guidelines... and those are good for what they are.... i do not follow that chart, although i can agree that it is a good reference.From what I understand, the useable footprints for HIDs are something to the effect of:
400w- 3x3ft MAX ( 2x2ft = optimal )
600w- 4x4ft MAX ( 3x3ft = optimal )
100w- 6x6ft MAX ( 5x5ft = optimal )
You can put as many plants as you want in this space depending on their size.
4"x4" per plant? that seems awful crowded unless you are talking tiny little plants. Also, you need to take in plant limits and laws- getting caught with 80-100 plants will get you 5-10.one 400w over a square meter with each plant using 16 square inches = 81-100 plants. Theres no reason for you not to harvest a pound every two months.
NO! federal mms 5-10 is for 100+ plants or 100+ kg. Please check the facts before you spread bad info.Also, you need to take in plant limits and laws- getting caught with 80-100 plants will get you 5-10.
