I have my seeedlings under a 400w hps w/ a MH conversion bulb...temps is b/t 70-76degees F...they seem stuck and haven't really grown, the one's in the smaller containers look great but the larger one's have not grown, the light is 24 in. above the seedlings, should i move it closer...i'll add some pics
should i move the lights closer, currently they are 24in. above the top of the large pots
close up
you dont need intense light for the seedlings, but you do... hard to explain, a flouro works great in the situation cause u dont worry about too much light or heat. Im not sure whats wrong with them but the light could get much closer, just watch for heat thats the only thing. Also they stay the same size for a while growing roots, they will pick up how long since they broke soil? it takes about 2 weeks for a seedling to start to really grow.
I'd be very careful about moving a 400W closer to seedlings. If you do that, and see the plants reacting with negative phototropism (leaves turning away from the light) then you're over lighting them. Safest course is to use flouro on seedlings. Alot of this is a waiting game.
Dboy
By the pics. I say kick back on the water and focus on some CFLs. You don't need to use such a strong lights before flowering. . .
hey all, well they'll be about two weeks old on Sunday, guess i'm not giving them enough time, i used cfl's to start the first few then put them under the mh and they look great,,,maybe i'll use cfl's for the first two weeks them put em under the mh...i know cfl's are the new craze...but everyone says mh and then hps is the ticket...i'll do some further searching, if they don't start shaping up after sunday, i'll put em under cfl's and see what happens
noticed that the plants today are beginning to show signs of growth, maybe its because i have had the curtain shut lately due to cold temps...currently its 30degrees F outside and my growroom is struggling to stay around 70 so i moved the mh down 2 in. and am using a lil of the heat to keep my babies b/t 70-74...let u kno what happens
leave the 400 at 24" when the seedlings slow down like that they are growing roots they will start to grow soon they look healthy be paitiont
Im in the same position after 4 days but i assumed they are growing roots. I havent watered yet since I planted 6 days ago. Should I water now and if so how much? They are in 1 gallon containers.
well, yesterday i moved it to about 21-22in. above the seedlings because the temps around my area have dropped, is this bad, the extra 2-3in. of closeness allows me to keep the grow room over 70...should i move em back to 24in. or let it go
new update on the boys and girls
these ones i guess are still growing roots
I think it's just impatience :P. They seem to be growing regularly to me. I mean they are only seedlings, they have slow growth. One time I noticed a change every 24 hours but now that's slowing down. Just give it some time.
