The Green Room

Regardless of what the numbers say on the digital device, if you are opening the tent and that's your thoughts, I would add a small fan to push air around and invest in an alcohol thermometer.   Consider spaying with water from a mister three or four times a day.  They love water intake through the leaf plus aids your attempts to up humidity.

Limited space hence the autos i do want to test if i can grow photos in my space though but do like a short veg keep them small. 50 for 5 i can do! 

The guy in hydro place said around 5 to 6 inches above just enough to lift the lid off, i see it on post within this site, a comment made after you says cfl need to be close..    I know what folk mean about not needing a whole tent for clones but what im planning is ive alreadt got 3 planta in veg doing really well on 18/6 and its them ill be taking the cuttimg from,, i then plan to do the clone in the smaller tent and let that grow as long as i can keep it there until my 3 plants are ready to come down, I dont mind if the cuttings stay there under the CFL for 6wk if need be, as soon as my 3 are cut they'll be moved into my bigger tent to do more vegging for a week or two and then flower and the smaller tent will become the drying tent for my 3 plants.. 

One was lumatek. Can't remember other. But I buy lumatek myself as I rate them. Have a lumatek 315cmh running besides my unbranded 23 yr old 400w..... My understanding is that whilst digital is more efficient, they are not as robust, and can fail after a few years..... Mags it appears are tougher.... Simpler components I assume....
