First grow - 150w hps
Hey everyone.
Long time watcher, first time do-er here. I have 4 plants going on which i grew from seed. Its been about 9 days since they sprouted.. For the first week, it was under a 22w 6500k flouresent lamp. I dont know how that affected it...but i dont think it was good, because it hasnt really done much since i put it under the hps.
Here are some pics!

I'm growing them in a closet, 2.5 x 2.5. I know i have four. but i plan to shrink that down to two or one once they xes.
I used potting mix similar to miracle grow potting mix. I dont like the proportions of fert in it...it seemed to be lacking in P but i did it anyway.
Im going to line the room with reflective film too...baby steps.
So im having a little issue with these plants...they look kind of stringy to me im not sure if its cuase they were under a 22w light for a week...or if they're roots are just growing under the hps.
My only other problem is temperature. I can't cut ventilation holes into the closet but i have 3 small fans circulating the air. The biggest problem is this small hps...putting off all this heat. The temperature at the plants is going up to like 90 degrees!
i froze 2 litre bottles and put them in there with the fans and that brought it down to 80...but its hard to keep it like that.
Anybody have good temp/vent tips?

not even a small hole for a PC fan?
i use 2x150watt hps and a PC fan was able to cool one of them, with both i needed more air going out.
90F is too hot, is there any incoming air?

No, no incoming air. thats my problem. I just dont have the tools nessiary to provide that for a few more days. Im afraid to make ventilation on account of smell though.

believe me the smell will get out regardless of what you do, infact it will build up in there and really start to stink the place up, is there a door to this setup you could leave open but a few inches?
this is probly the biggest issue people have and there really is no way around venting the area, is there a reason why you cannot cut a hole in the closet somewhere....even the roof of the closet with a fan pulling out would help you greatly.

the reason i can't is due to tools right now. im working on it in the next coming days. I've been able to keep the temp to about 80 degrees. Thats close enough for jazz right now.
Im finishing the closet setup, ill show some pictures later.

okay. down to 81...lets hope i can keep it down there. I might just have to start keeping the door open or something...i hope not.
Oh, and when y'all measure temp, do you tend to take the temp from right near hte plant...or the average temp of the room? i have my meter about 6" from the plant.

sweet! thats kind of a relief actually. i just know that 90 is dangerous.
I've been regulating the temperature with ice, so i guess i'll just be workin hard.
I wish i could figure out why my plants didn't look so good though.
the leaves have been getting less green more yellow...especially the veins. They're like yellow lines

Ok for starter your CFL will be the best thing to veg your plant, HPS are more for flowering, but the one CFL one do jack to 4 plants. Using CFL's bush them out more and if you place them 2 inches above the plant won't stretch and therefor have good stem growth too.
Your problem with yellow veins etc. will probably be from lack of phosphorous or general minerals. Try to give them a little but definitely not to much, you don't want to go down that route trust me!

the yellowing is most likely the soil you are using, MG soil just isnt that great for herb plants plus it usually has some sort of ferts in it which isnt needed for the first 3 weeks or so.
what i would do is find some organic soil at a flower shop, should cost no more than 5-6 bucks a bag, and transplant them into the new soil, if your careful and dont mind taking the small risk i would break off all the old dirt from the roots before i placed them into new pots that way you know the old ferts are no longer present.
when my cab was running in the 90's my plants didnt look that great until i was able to vent the area better which is what it sounds like in your situation, they do grow in high heat they just take a lot longer than normal and give off a shitty appearance.
was you able to obtain any tools yet?
get more pics up too.

bah. i messed up the pictures. ya'll gotta wait til sunday now. sorry
In the mean time, Im going to buy some top soil and peralite to make my own potting mix and then transplant the little guys. Does this sound like a good idea? its hard to find a good soil....i just returned my MG soil. Does my mix sound good?
Also....whos got fert tips? for veg, i've seen So many different things. I read that lower N is good for temps above 80. that would be me....i think i might just go to a hydro store and get some veg nutes and some superthrive.
Coments well accepted.

Superthrive is good, remembers its very concentrated. Get some Neptune Fish fertilizer it does wonders!!

for veg you can use anything with a higher nitrogen level than the others (N-P-K) and Neptunes Harvest makes some of the best if not the best nutes you will find,thier seaweed mix is some good stuff and great for veg and micro nutes.

Hey all!
long time, no update (with pictures at least)
I transplanted into bigger pots. Im not worried about them being big enough because i only intend to have one (or two) plants in the end of this grow.
After transplanting them, i watered it with the Vigoro Root stimulator 2-5-2 Fert. I hope this is a godo thing lol. I havn't used the MG 12-4-8 fert yet...cause everyone always talks bad about MG. So ill wait to hear comments. Key: its MG liquid feed All Purpose Plant Food. 12-4-8.
I've got these plants on a 5 day water cycle, i hope this is enough. I dont think im watering them enough thtough...im gonna wait 3 days and see how the soil is.
Anyway, here are some pictures....let me know what you think cause they are looking kind of droopy (im assuming from the root shock?)

Wow looks like the beautiful start of an excellent grow . Your plants look really good to start, I have seen alot worse plants survive and yes maybe the plants have been stressed abit from transplant, but dont worry they should perk up a bit soon.
I really like your grow cab, lovely reflection
Good luck!
{edit} I don't know anything about MG so sorry can't help you. My fert is 6-5-5 and its fine for me.

Stone: Thanks! im glad to know they at least look ok....im so scared to kill them i fear im over nurturing. lol I like the closet too, its really small...perfect for 1 or 2 plants. ;-)
Kaj: I used ACE premium potting mix initially, but transplanted them into pots full of Scotts preimium potting soil (which seems better). My only regret is not putting any perlite in them...i feel like they hold too much water and don't drain well...
Anybody know how i can help this? it seems imposible to add something at this stage to help drainage.
