(increasing both levels simutaneously as plants mature)

This is somethin i have recently read and have been looking into as you may have read on my most recent posts.A question which will require more involved research as not many ppl are familiar with this as i have found.Most ppl i read about use 1500 ppm during flower and some use this through out their whole grow,while a slim few say 2000ppm works beter although i feel through my extensive research this is a waste.This new concept of matching ppm with co2 and nutes is interesting though and would save co2.Ill be looking for more info on this as i know you will too.

flouros or cfl are good for them, & when they are new sprouts youll need about 800-2000 lumens to keep them healthy, but the rule of thumb is 50-100w per plant or a minimum of 3500-5000 lumens by wk 2.

u shouldnt need to feed until wk 3-4, & u shoukd start @ 1/4 stregth & go up slowly. to know when to feed the plant is prety good @ showing u when it need food, but usally feed 1 time a wk or 1 time every 2wks

the fans need to be on where it blows the leaves around, not a wind storm, but like nature would do, & dont put a bag over the plant, & humidity is not a big deal, but it helps.

it would make since to do so, b/c when useing co2 u speed the plants growth, so it woukd use the nutes quicker, but ive never acctuklly heard of that

i also did some studing up on ph levels and found that mine were way out of wack, so i fixed it to night the best i could. i will have to get the good up and down stuff tomorrow. but hopefully they will strigten them selfs out in a week or so and not die. thanks for all the help.

What do you think of this statement? "Dont use aquarium PH up PH down.Its bad for your plant" That's what I'm currently using.

JCJ; Since most use the PH down nearly all the time,can you recommend ANs barricade for PH down as the directions state it can be used for such?

[ocitown]

JCJ please see my #919post.

Suspect see my #920post.

hey i grabbed these bulbs the other day.

2600K each bulb


1600K each bulb



i have a feeling that one of these should be daylight bulbs and the other cool white.

can someone please correct this for me? i know i'll be having to return one of the 2 bulbs and buy a diffrent one, but which one should i return?

got what i needed searching. man this forum has a ton of info. during my reading it also cleared up some ?'s i had.

Lumens and Kelvin are 2diffrent things..

The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units.


The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the perceived power of light. Luminous flux differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light.

Lumens is the power of Light
Kelvins is temperature
