light question on newly transplanted clones

[bronc76]

They will freak out worse with less light than necessary. I have been vegging mine out doors then moving them into tent with a 1000w hps beaming down onto them from 24" away. Havent lost one yet from too much light. If its too close you will notice and can move it up some. Remember lumens= yield. The more light they have the more they produce. I just put some under two 24" T5 flourecents from seed to about 4wks old moved into flower and they are doing great. Hope this helps imp:

Here's the thing I don't quite understand about temperature: I read everywhere that 75 degrees or so is optimal. I also read that you can put your light real close and as long as your hand doesn't burn after a minute, your plants would be fine. So my hand can withstand temperatures way higher than 75 degrees! This seems like conflicting info--can anyone clarify?

Apologies if these seem like dumb questions. I have spent lots of time doing lots of research, but some stuff just doesn't seem to add up.

I got the 250 hps way closer now, and with the frozen water bottles and the personal fan blowing over them, I am down to 76 degrees during the day. Whoohooo!

Still confused a little though. Can anyone answer my question above?:jointsmile:

Hey Sprite

"Here's the thing I don't quite understand about temperature: I read everywhere that 75 degrees or so is optimal.

What they are referring to is the ambient temperature of your room, not the temp directly underneath the lamp. You should be able to withstand the heat of the lamp without burning your skin yes, and I guarantee you the heat coming off the light directly beneath the source is higher than 75 deg. Your Hygrometer, or Thermometer should be mounted just above canopy level in the shade to get a correct ambient temp. Keep a lot of air moving around the closet and get that ambient temp to stay between 72 and 81 deg with the lights on.

Good luck man and keep us posted...

Update? Hows it going with the light closer and temps down? :rasta:

Heh. I just saw this message. Going GREAT! Day 40 flower!

I never understood that either!

I've had plants burning like crazy when my nutes and "salts" were way out of hand. The bad tap water was compounding the problem. After getting ppm/EC under control the dang plants can touch the air cooled hood glass and just thrive. No signs of burning nor bleaching. Go figure.

I have noticed freshly planted clones need to stay more moist on the surface than usual seedlings or plants. It's sort of like when you plant a seed and you can't let the surface dry out too much. In a dry hot climate the area around the plug/puck/cube media can dry out. When the soil drys so goes the roots. Dry soil will also "wick" the moisture from your clone media.

So as to not over water one may use a spray bottle around the small plant a few times per day.

During that first week I wouldn't hit them with a big light. Yeah, more light than they had in the coning dome, but not a HID lamp either. You gotta work up. IMHO that is of course.

Cheers, DO.

After I put them in dirt, I turned on the 250 watt HPS (I know MH is better to veg, but this is what I have now) and within 2 hours, they looked floppy and stressed.
