Thank you slunt.
I realize 87 seems a bit warm, but i should add that there are no obvious signs of heat stess, no burnt tips or yellowing...(except in some older foliage which is due to lack of nutrients, i believe...i have had a hard time finding FF tigerbloom, which is the fert. i want to use for flower, and have been adding organic "super phosphate" pellets to the soil, just till i find the tigerbloom.as well as recently adding some organic liquid plant food made of worm poop) the only signs i say could possibly be heat stress are the stretched pistils...they are very pronounced, but not dying at all, thought it could just be a pheno thing....as i said my plant is a almost pure sativa with haze genetics somewhere along the line. sorry dont do piccys. My hand is warm when under my lights (which are 450w now, but i plan on adding about 175w more during this next week.) but do not feel "uncomfortably warm". put it this way, i wouldnbt be worrying about heat at all if my little digital therm lying on my screen didnt often go over 90f. moving lights away is not an option, as they are already ~1ft away and i feel any further will be bad for the plants light consumption. Before adding more lighting i plan to add one more fan directly at a bulb, to reduce heat....my mate is also unlatching the windows to his room and turning the electric room heater down to 55 more often..
in conclusion of all that rambling, heres what it lead up to:
HOW CAN I GET LOWER TEMPS??????
while i dont think the amount of heat i have now will kill the plants, i feel it will deminish potency, and yeild. i also believe, from what i've read, that growth will be better with lower temps than i have now, and some minor fungus and pest issues will probably go away with temps a little lower.
And i don't know anything about wire guage, my lamps and ballasts are wire directly by fairly thin, normal household extension cord wire...have been fine so far, my largest bulb wattage is 150, and i have tested a 150 wired this way for about 5 months and no problem, now i have 3 150s and am adding a 70 and a 100....while they are all using the extension cord wire, they are all plugged into the surge protector heavy duty power strip with a max load of 1875w, im only using about 800 with all exhaust applications iuncluded.
Also i think im gonna do the yeist and sugar thing for co2.
thank you.
