Can Afghan Kush take 90-95F temps

Right under the lights? The fops would be within 2 inches of the bulbs. It is supposed to be a landrace 100% indica isnt it (world of seeds).

95f will stress your plant.
If you have heat problems I recommend you to use silica, Dyna-protekt is my choice.
I dont put my ladies that close of the lights.. 6" - 10" you will be fine..

What about if they are t5 h.o. bulbs.... :/

t5 is good to start. If you are not able to get an HPS (at least 250w) I would go with Cfl's ... the thumb rule is minimum 100w per plant

a big trick to help the plant to deal with hot days. guys shhhhhhhhh its a secret . ( lemon extract ) and sugar . lemon is vitamin c that helps the plant deal with high heat and stress vitamin c is found in nutes that cost 100 a bottle . for heat stress. but not listed. sugar is carbs. and tends to make the bud stick together more not fall apart. just make sure you have a large fan going . it should be fine I flowered at 100f plus before it came out well every body liked it . ow teaspoon per gallon lemon . sugar. the same. no worries its very hard to over do it with sugar and lemon juice. just check your ph after adding it .

I'm not clear on the mixing instructions for the lemon extract and sugar. How much sugar and how much lemon extract should I mix into water? When you say lemon extract are you meaning squeeze fresh lemon and add with sugar into water? Cheers!

Sativas are tropical warm weather plants but not indicas. They like it cooler.
