How far should my 250w MH bulb be from the plant in first weeks of vegging?

edit:
What do you guys think about this plant, it was trasplanted yesterday and I started to give nutirents in mild dosage. Leaves look king of down, is it overwatering/overfeeding?View attachment 2386782

Way to early to be giving nutes man. If anything I would of done plain water with a dash of super thrive when doing a transplant. But mj is an amazing plant and can repair herself if you show her love. Oh and btw plants wilt after a transplant that's a major shock to them hence the super thrive

Oh yea how close you can get a 250 depends all on your setup man. I have a cool tube and I can be 4 in above my canopy with ease.

If by wee test you mean trying an air pot, I am doing just that, with the exact same pot, 7litre i think...the roots shot out the bottom crazy, thinking of getting some bigger ones for my next grow, under a 400

As said wait on the nutes. I had issues from nutes too early myself. If you are using a premix soil wait about 3 weeks after transplanting and go with a low dose, say 1/4 recommended and work your way up..

I had my MH about 12 - 16" up for the first week after switching from my T5, then dropped it down. I was able to stay 4 - 6" most of the time, however the heat made my buds a bit loose and airy. So keep an eye on temps, if the inside of your area is under 80f then you should be fine just keep good airflow between the plants and bulb, it tends to get a little warmer there...

Thanks for the rep man! I keep trying to give it but it keeps telling me that I need to spread more to give more lol. I don't get it.

I can keep mine at 4" but it's also in a cool tube with a 300cfm inline fan blowing air across it with a 4" inch inline fan for my exhuast. Temps stay at 75-78 lights on and 66-68 lights off. My girls are loving it.

Have you done any autos man? I'm doing my first batch of them and they are some funky things.

giggles, your 2 tent exhuast to box, then second fan idea, sorry keep forgetting to post.

Guy at the hydro store went to a big expo the other weekend, and when we were chatting after, i flicked through a brochure and saw a box, ready made, just as you havein mind. Baffled inside with foam to kill noise, but I recon they will be ridiculously expensive and much cheaper to make.

It should work, but one thing I would consider is the air flow quantity, and size of the box. If there is a lot more air being pushed into the box then can be drawn out, and little space for movement, pressure issues could affect your fans.

Right, just checked the weather, and the humidity is gonna stay between 80-90% for the next few days at least. Mite have to bite the bullet and buy a dehumidifier, right in the middle of harvest

Fucking weather!!

Bro I am feeling you!!! I am 2 weeks in and they are my autos that only flower for 45 days and my fucking humidity is at 58%. I may have to get a dehumidifier as well. I'm not really wanting to. Opening windows and fans are not helping enough!

Also at day 43, humidity at 75-80 and that's with the silicone dehumidifier crystal things, it's horrible. I'm keeping aiirflow 24/7, minimising watering, and basically gonna let them dry out to total wilt, then add just 300ml pure water every 5 days for a couple of weeks before harvest, give them plenty of chance to rape the leaves and get all the good sugars out of them

I'm not so happy. The money I was going to use to buy another tent may be going to a fucking humidifier now!!! grrr. I have 2 of those silicone things in my tent and it's not helping!

Well hetty I got my problem solved. Not sure if it's a good thing what I did but I did it lol.

I put another 4" inline fan exhuast in at the bottom of my tent lol.

Came down to a nice 34% lol. So far so good.

When is it a good time to start giving co2 ?

I have a spare outlet hole in the top of mine, and a spare standard bathroom extractor which I use in my drying chamber, might put that on. I'll lose the carbon filter smell protection doing that, but for a few hours a day while i'm home should be ok...i hope

ive been quite lucky in the fact that im in veg so the 85%rh isnt that much of an issue. cant believe ive jumped to 6 plants. hope my 250w hps and 2 45w cfls will be enough. got a couple 23w as well.

I know your feeling man I lost my carbon filter but RH was getting out of hand and I didn't want to lose my crop to mold.

I hope my idea works for you bro. Just thought id share what worked for me to help another grower out.

Yea that's what I thought to man and then next thing I knew I was in flower scratching my head saying wtf do I do know lol.

Of course the 250 can handle it bro. Its such an underrated light and u have supplemental lighting you will do just fine bro.

On the plus side I convinced my missus to let me get a 3x2x3 tent for vegging and my mothers. Im pretty fucking stoked.

If you are running a co2 system then give it to your girls all the time. Bitches love co2 lol. Nice thing about co2 is you can have higher temps and still have great results.

i hate women, i asked her before i started and she said fine. its mad because the reason she broke up with the guy before me was because he blew 60k on converting his loft to a factory. im growing a couple plants in the cupboard for personal consumption and she pre approved but isnt happy about it so she wants me to move it outside. ive kept her out of the loop this time so thats why im doing 6 plants.

Lol tell her its the wrong time of year to be moving outside! Sometimes we just gotta do what we think is best and not listen to the women lol.

If she dont want you having all those plants brett ill gladly take a few lol.

60k on a loft factory...how big was his fucking loft!!!!

Like i say, mine has just given me permission to do a couple of larger grows under a 400, store up some jars, and then stop while we think about relocating next summer. When we move I plan to set something up, having it running for a couple of months without her noticing, the tell her, and maybe sell a couple of bags to buy her something nice. I only grow for personal, but always try and sell a little to one or 2 close friends, and give her some money for electricity and take her out to dinner. Amazing how her morals fade away with just simple actions....

Also running 6 plants under my 250w with 4x30CFL, one in each corner of 2x2, and they are doing fine. Just don't try and fit 6 monsters under there.

Got my humidity down to 68% today, with open windows and plenty of moving air. Gonna rig up the second extractor later and see how that goes

Let me know how that works out for you bro! Hope I was of some help.
