24/0 >> 18/6

thanks to everyone, really.

i followed psteve advice and noticed that all my plants together form a square nearer of two feets.... so here some pics my friends.

Alright, in the photos...one is my setup, other are were my plants are inside, and one photo, is a close up of one of the afgani, that seems to be lacked of calcium, wtf?, how can be a lack of calcium in a 1.5 week old plant?


By the way, i am repotting today with high amount of humus, i was thinking 50% humus, 25% perlite 25% organic earth. how about it bros?

Are you watering with distilled water, or water purified by reverse osmosis? If you're using tap water, then I doubt it's from lack of calcium. Also, if you're using any nutrients... stop. Your plants are too young still to be fertilized. Fill out as much information in the Troubleshooting Form as you can, and you might want to post it over in the Plant Problems forum.

Your lights are MUCH too far away.
Put them about one or two inches from your plants.

This is true as roots grow mostly during the dark period.

I believe in the last pic it is his 400MH in which case he wouldn't want it that close.

then nobody would ever be able to go 24/0 under MH, I read somewhere that you need to give your ballast at least a 15 min break once a week. I haven't found anything about once a day..? :jointsmile:

You can do 24/0 using TWO mh lights. Just have them rest at different times.:thumbsup: I've never heard of the 15 minutes once a week, and there are very few timers that will let you do that. Most folks I know let it rest for 2-4 hours per day.

Well a quick 15-20 min a week thing can be done manually easier. But here I found this link on a hortilux bulb where it says weekly, and also on philips site with theirs as well.

I'm not trying to contradict you in any way but this could change a lot of things for a lot of ppl if you really had to do it daily.. I would hate do have to do that if i went 24/0 lol :rastasmoke:

Oh yah btw I'll be road trippin to your end of the country in may to look for areas to live in, I can't frekin wait! :D

well i think what caused the problem, i used about 90% perlite and 10% earth lol, but its ok my plants are fine now on 60% humus 20% earth and 20% perlite, also i perfored my pots so they are like swiss cheese, by the way the afgani is extremely bushy =X ....

Glad to hear things going smoothly for ya! A 90% perlite mix would be a good way to go if, and only if, you plan on supplementing fertilizers exactly when the plants needed them at exactly the right time. Sounds like your new mix should be much more accommodating.

Take care, and best of luck! :jointsmile:
