I have a 400watt HPS and i just want to know will this do for veg and for flower? and how far do i keep it away from the plants in both stages of growing. thanks
Usually HPS is used in flowering stage, altho some growers use it all the way...
The distance will depend on how cool can u keep the bulb, the coller u can get her the closer will u be able to put her on top of ur canopy, currently i have mine at about 18", plus 4 x 18w 6400k fluoro tubes in my grow room...and i dont have heat issues (so far)...
thats fine, if you have to buy a single light, HPS is the one to get.
just make sure your temperature is good, and dont put the light to close when they are babies.
abut 12 inches above is good for both. when they are babies you want to protect them more, or put them on a window sill for the first few weeks, then when they are strong, put them under the light.
The Light i have is a 400w HPS Dual Spectrum Grow Light - Hydroponics HID to be more pacific, thanks
That is perfect to go all the way since the bulb covers both light spectrums, if ure starting from seed get the seedlings a foot maybe a 1 1/2 feet away, if ure starting from clone u can go a bit closer, just remember the cooler u can keep the bulb the closer u can put light....the closer the light the better the plants will do...Quote:

No u dont need to change the bulb dude, as for the distance like i told u if u the cooler u can keep it the closer u can get ur plants under it....and yes to flower u just need to switch to 12/12 and change the nutes...appart from that i can only wish u a happy grow
thanks for ur help man much appreciated, could you tell me wat is the best nutes to use for when i switch flower, i was thinking a soluble fish emulsion wat do you think?
Get your air flow right and you can bring your light as close as 12-14" above your flowering plants. According to many growers, the close the light to the plant, the better! But you must check them daily to ensure there hasn't been a growth spurt and the fresh tops aren't getting stressed by heat. I keep 600W HPS around 24-36" away from freshly potted clones for around 1 week or until they look like they are striving in their new home. I then lower the lighting by 12" and keep the lights around 18-24" from the tops from then on until harvest. If I had Cool Shades I'd keep them closer. Adjusta-wings are good because the heat dissipation keeps the area between the plant tops and bulb relatively cool in comparrison to other cheap shade that I also use when I miscalculate space and cutting survival rate.
gee, much happened in the time it took for me to type that lol
Flush your soil (i.e just water no nutes for a day or two) between 18/6 and 12/12 to help eliminate chemical residual build up in the soil from nutes that aren't likely to be used much by the plants once the cycle changes
Thanks man for taking the time, you are all helping me out big timeQuote:

at the min ive got my light pretty far away cuz im a noob and DO NOT WANT TO BURN me babys. yea the soil drys out pretty quick, but only the top.under neeth will be plenty of water..never give your babes to much water.if the soil is dry and crumbly. give it a good spray. i would spray twice a day but not heavy at all... also i dont use nutes or nething yet.. im very basic...and their growing..
Failte Raibhat TBB
cherrs, im setting it up now
also if they havent broke thought the soil yet. leave it on the window sill for a week..no stress just patience.. believe me thats the hardest part to growing.. GUd Luk
ill take a pic and you can tell me if im right or to close or wat, ill take one now
ok ill have to wait till me sister gets in to get the camra off her,
I set it up temp is raising big time and humidity fallin big time hum 30% right now temp 33degrees wat will i do?
i put a small fan blowing on the light temp gone down to 31degrees,
do i leave the light on 24/7? they havent broke thought the soil yet,
Can Anyone help me out??
Here are the pics i took just
can you tell were im gone wrong?
you can do either. Both will work.
Your setup looks fine. Just wait for little seedlings to pop up.
What is that little thing you have taped to the corner? Lower left corner of pics?
Its A surveillance cam, so i can keep an eye on things from my room
saves me jumping up and down
Are the temps alright do you think?
it is ok. but lower would be better. Optimum growth happens around 74-77F or like 23-25 Celsius. Its really hot where i live now San diego and my ladies have been up as high as 100 deg. farenheight. They are doing ok.
will it be alright like this when they start to grow? the humidity it only 32% and temp is 32 Celsius
thats a nice wee stup mate.. love the camera to.you best bet is just to wait till the seedlings pop up then put ur light on. humidity wont be a problem. if youve fans on..the attic looks big thats good to. means the heat will spread out. honestly dont worry about humidity or temps.. yet.. pics look sweet.. ps dont let the soil get cold or it will slow growth.. Looks greaet sorry i couldnt get bak to you earlier.. Peace TBB
Thanks man,
so will i not keep them there on 24/7 till they pop up? were will i put them?
and when will i have to start worrying about humidity and temps,
Cheers mate
nah man not 24/7 when the seedling comes up put it on 18/6. what strain is it? worry about hum and temp when the stem gets thicker and youve loads of leaves.. a big attic is the shit,cuz its nice and dry, my grow is pretty much the same as yours. ive four plants one indica and tthree sativas.soo they will grow at different rates thats where i fucked up.. but as for them meen time, just be paitent and wait. YOU HAVE ALL YOU NEED TO GROW SOME NICE BUDZ ;);):)
i dont know the strain, my sister brought home a load of seeds from jamaica they all said it was some shit, they were parro outta the head and all that they says they never smoked anything like it, sounds good to me.
Will i put them on 18/6 now? dam humidity is now 25%
lol Jamica must be good..did ur sis buy them or get them of sumbody.honestly man your set for some buds in two to three months..Dont forget the humidity will change with the weather, specially in a attic... ..thats why peaple build boxes or rooms.. so they can control everything..dont get me wrong thats what you want to do. but on a basic grow all you want is a scource of energy(sun,,light) some food(water) and alota paitence. peace bro.. stick around here btw and you can diagnose any problem you get by typing it and waiting for a replie..loll SMOKE UP DA FUCK
yeah it sounds like good shit, she got them out of the stuff they were smokin over there, yeah me brother is building a big box or 2 up there for me on saturday hes a good chippy,
Thanks for all your help man much appreciated,
o yeah will i leave them under that light on 18/6 or what?
It't best i think to grow the babby's under flo.then h.p.s.just have plenty of ventalation. keep temp.at68 -70
lol nah i would just leave it on the window sill untill they pop uot its just a waste o electrik. as soon as they pop out bang them under 18/6 to 24 if you want.but be careful they dont burn..
