I'm going to grow one plant for personal use and I'm not to sure how big my grow box will be but I want to know how many 100 watt equiv would I use for the plant

JN811 · Nov 18, 2009

id say like 10.... for good growth..

JN811 · Nov 18, 2009

those are 26 watts right?

JN811 · Nov 18, 2009

darkdestruction420 · Nov 18, 2009

how big you want to grow it? how long do you want to veg? planning on fimming/topping/lst/scrog it?

They are 100 watts equiv and 23 watt's that it uses

if you want a grow thats gonna be decent size and speed id go with at least 8, the more the better as long as you can control heat

JN811 · Nov 18, 2009

just dont use like 4 and expect to grow anything good...

Is 6500k the one I want to use because that's what I got and would I just put all the lights above the plant?

put the light bulb horizonatally so the entire side of the bulb is looking at the plant. Why not go with 42w, 150w equiv? And 6500k/daylight is used for vegetative(the first step) and around 2600K/soft white is used for flowering(second step)

ya you'd just put it above, but i agree id just use some 42w, it would be a lot easier, ya actually 6500k is blue for vegitation

I was growing a very healthy plant under two 26w and two 15w 6500k CFLs(5000 lumens all together) and the main stalk was the diameter of a dime. i fimmed and supercropped to keep it short so thats probably a factor but 4 lights worked well for me. Roseman has a thread about CFLs and says you need a minimum of 3,000 lumens per sq. ft. and 7,000 to 10,000 is ideal.

4 23w per plant = roughly one ounce per plant if things are done well.

true the more light the better, but i had only used one 23 wt daylight cfl for the vegging period and got great results for the vegging. now ofcourse iv added sum light for the flowering. pics were taken prior to flowering

Lowrider3 · Nov 19, 2009

When doing the veg stage would u only use the 6500k bulbs first or would u use 2700k and 6500k together? And if so can u use these light's for the veg and flower?

original poster-use all the lights you got.
redredwine-something is up w/your plant, its not normal for the tips of all the leaves to be like that. whats your ph?soil type?watering schedule and amount, feeding schedule? temps?

im using scotts potting soil mix. its my first grow so im making mistakes i know, but i dont know the ph to be honest, i water every 3 days or so and just enough to have a little run from the bottom of the pots an i havnt been giving them any food. the temps are about 65 to 70 and i dont have any control over the temps

i used all 6500k in veg and all 2700K in flower but people recommend mixing spectums. just use more 6500k bulbs than 2700k in veg and vice versa for flower.

heres a thread about it.
