how far away...
1. overhead
2. approx. 4'...under 250hps
3. small fan dedicated to 250hps/there is also a 16" recirc fan in room

The temps in here are usually around 70-80f, but when the door got closed the other AM...temps blew up to 90+ and clones wilted. I removed them to an airy room and spritzed them...It looked like 9-10 might make...but, then yesterday AM...the same person that closed the door and killed them in the 1st place, took them without my knowledge, stuck them in the dark and they all died, as far as I can tell...who knows...

4. seedling box-day2
5. my C99xNL5

GK, I put my seedlings under 1000w horti- in my sneakpeek thread...they were clones, rooted for 2 weeks, then I vegged them 1 week-15/9 and flowered them 12/12 for 6-7 weeks...all under 1000w horti-
...As far as airflow; I have a 5000btu window unit you see in wall dedicated to lamps airspace...
and a 16" recirculating fan(too much) in all my rooms...
temps always kept between 70-80f...humidity varies 46-75 at times.

Did that answer your Q's? You know that in sneakpeek thread, you can see all this! thanks for the response.

I can't believe that with all these experts we have around here...no-one bothered to try and help with this query...and to think, everyday, I take time to help some poor soul. Oh well, I blame myself for trying a new method I am not familiar with, at a major cost to my perpetual grow!!! I lost 20 Northern Lights and 10 Misty blue clones here,,,BUMMER

I gotta go! lw
