i dont know, ive had others see the same thing, all i can say is u cant compair 1 to another, but i think hanna is a better product.

dl works more slowly over a longer period, & i dont think youll need epsom salt. ive only used it once a few soil grows ago, & my plants have never shown mg def when i dont use it, but it seems calmag has more benifits than dl, b/c its already buffered & has calcium, v-d, v-k & other trace minerals

and vigorous air movement both above and below the canopy.

does the c02 enrichment hasten the veg stage or the flower stage, and how much time will be shaved off?

it can be used for both veg & bud,m but most just use it during budding, & ive read somewhere that the propper use of co2 can increase growth by 200%, but im not sure on that. co2 wont make the plant finish budding faster it just make the buds bigfger & more of them, during veg it will speed up growth.

I honestly didn't think they would germinate. And 4 out of 5 seeds did. And i'm pretty sure the 5th one will germinate in another day.


now i'm debating on if i should go for it or not. I'll be buying some soil 2morrow from wallmart or homedepot. Which ever is cheaper.

then i guess i'll be buying some CFLs. and buy a cabinet or something to put em in.'

any tips or advice?

here is a simple cheap basic setup that i think i'll be going with...if i do fall with the growing thing.





I'll be hanging all CFL's over the plants about 1.5 inch away when they get maybe a good 1' or so.
That sound any good?
I'll be using all reflectors on the lights as well. Would this be tooo much light?
here is a link to the bulb im thinking of getting

here is a link to my thread.

looks good but id mix those cfl, ide get both 4100k (3) & 5000k (2), & paint the walls a flat white & youll be set, & not too much light, more is better. the sun puts out 100,000 lumens per sq ft.

I haven’t added nutes to them yet and they are about 3 weeks old. This just started a day ago when I watered them. I did use tap water instead of distilled water from the store this time could that have something to do with it maybe. Thanks for any help you can give.

Update

Ok im not sure if I did the right thing or not so let me know. but I went to the store and got gallons of distilled water like I have been using for the last 3 weeks before this problem and flushed the plants potting soil medium with the same amount for each plant. About 2 cups in a 16 oz pot (plastic cup). the main thing I notices is that on most of them the water running out of the bottom was a yellowish color some more then others. Did I wash the nutes out of the soil or why the color in the water. This is my first time growing indoors so I could use a few answers please. I think my outdoor op was less completed. Just plant and harvest. lol

More Info

They are under 90w of flows untill I get my 400w mh this week from fedx. I’m not sure how accurate the ph is because of the way I checked it with the lit paper. The room is at 76 deg 45 - 52 % humidity and I just watered them before they started looking so sick. I thought that maybe since I have city cleaned water from the tap there might be too much chlorine or fluoride in it for the plants. So I guess I will just see what happens since I flushed them huh. There has been a fan on them since the start. It is miracle grow brand moisture control potting mix. .21-.07-.14 nutes per bag. Best I could get over the counter. You got any idea about the yellowish run off.

Update


Well I have concluded that what ever the yellowish stuff was that washed out was a good thing because I took a cup of fresh dirt and ran the same amount of water through it and it came out clear. So I guess ill see what the result is in a few days

Update 12 hours later

Some seem to be doing better but a few others the leaves are starting to curl upwards and there are both light and dark green leaves. I hope they come out of it but I would still love to know the cause if any one might have a guess. thanks

1st the dirt is that color b.c its dirt, 2nd that mg moister control is bad news, i used it 3 griows ago & had probs all the way till harvest. u can let your tap water set for 24hrs w/ lid off to let the chlorine evaporate. u can add hydrogen peroxcide 3% @ a rate of 1-2 cap full per gallon to help get extra o2 to roots & help prevent overwatering, the leaves curling up , could be from heat, or a mg def. the best advice is to get them out of that soil & get some that dont have ferts already in them, they are timed relerased (bad for mj), get the mirical grow organic & mix some perlite in it.

Thanks, i'll be buying some bulbs once the store opens. But i don't know what they'll be having so i'll be basically shopping for bulbs between 45 - 105Watts.
i'm kinda broke. haha and i dont want to spend too much cash. the most i would like to spend is 120$. 200$ the most. untill i'm done paying off bills that is!

If i don't get 4100k will 2700k be ok?
And 5000K is the same for all bulbs no matter what the wattage is right? i mean besides there being a 6500K. i just have to look for it, correct?

Do they actually say Daylight and cool bulbs? on the Cfl's i mean.


I'll be going to Homedepot/Lowes.


and also what kind of soil should i be getting?
What do you recommend for a 1st time grower?

yes youll need 6500k or 5000k for veg (cool white), & 2700k or 3100k for bud (warm white). youll have to look at the bulbs K rating, b/c they go from 10,000k - 2700k, so for veg get as close to 6500k as u can & for bud get as close to 2700k as u can. ide get mirical grow organic soil, & some perlite & mix it in w/ the soil

[SinisterCyclops]

what type of lighting would be ideal for seedling growth?
Someone mentioned cfl's earlier in the thread i belive, but how many lumens should i have per seed?

Yea, the idea of c02 enrichment got to me to. When you do it, remeber to give me some tips

[Rhaas2001]

jcj77d thanks for the advice i never thought about the soil being bad. will fix the problem asap. thanks again.

[Rhaas2001]

ok so i got a potting soil mix of canadian peat moss (55%) with Perlite and Vermiculite mixed in. there should not be much nutes in this soil so i have some Miracle Grow all Purpose Plant Food my girlfreind uses on the house plants. the dir say to mix 1/2 teaspoon per 2 quarts and apply every to weeks. but i have read to start them at 1/3 strangth till they get used to it. do i still only apply it every to weeks. under my sitituation what would you recomand to not cause any more damange. plus im going to start a new crop because i think this one might be lost. thanks for the help

[Baked potato]

how far should i put the fans on and one more thing, kind of stupid quesiton but if i put the plants in a plastic type bag to hold in humidity will the heat from the light [x2 CFH42watt, (150)] be able to transfer through this, is humidity really THAT big of a deal btw.

You bet!

[suspect]

Im planin onaddin co2 very soon. My question is........

when addin co2, is it a good idea to set the ppm @ the same level ppm as the nutrient solution?
(increasing both levels simutaneously as plants mature)

Taken from the "CO2 ENRICHMENT GUIDE" by cecil_b (The Garden's Cure forums)

"Carbon dioxide enrichment involves increasing the concentrations of CO2 to 4-5 times the normal atmospheric levels, to between 1200-1500 ppm in an enclosed space. Levels higher than 2000 ppm have been shown to retard plant growth. Low levels of CO2 (below 200) have been show to halt vigorous growth.."
