Need help with grow box

Okay this is my first time growning mj myself. So i have a few questions. I made my grow room out a old chicken coop we had and i saw people put silver stuff on the walls. Well i was wondering what they used and if it is neccesary. I read somewhere that using alluminum foil is not good because it will create hott spots. I'm using a chick light with a red bulb to kinda warm up the grow box, I have the box in the barn and it is starting to get pretty cold so i was wondering if the light could harm my plants. I'm also using 4 CFL lights, if i turn on the chick light to warm it up do i also have to turn on the CFL lights? and could someone tell me if i did something wrong with the grow box or if i need something else or whatever. I'm new to all this so any advice is good.

pic did not work but most light is good light, you might want to add a fan and carbon filter how big is the chicken house your using?

O crap ummm how do you do the pictures then, and umm i will go check the measurements

i'm the person u ask about growing, not using the comp. lol are u going to use soil or hydro? bagseed or seedbank seeds?

Lol the measurements are 42x31x48 and i am using maracle grow and i got no clue from where the seeds are, my buddy had a few plants and got more females than he expected so he gave me a few.

nice i'm MG user as well, are the plants big anuff to be flowered? or they need more time? remeber veg 20/4 flower 12/12

Well they are still small, but two looks like its already in the flowering stage so i just kept the light at 12/12, Should i change it to 20/40?

idk it up to u, u can try to reveg them trim the buds of slowly, and make sure u dont kill it or get mold, or u could just let them flower 12/12 and get some bud pretty fast and them your next grow order some seeds online and have some danky dank dank

Well all it has is like a few tiny little balls thats it. Its not a full bud yet

buds with little hair like things? or hard green pods? u might have a male or a tranny in your box

Well its not a male it has those white hairs all over. Its probably a green pod, i haven't touched it so idk if its hard. I have like 2 or 3 on the two bigger once.

well they will become little yellow flowers, so i guess u got a tranny on your hands, u can cut the pods off and battle it every day, or u can just let nature take it place and get less potent produce and get a shit ton of female seeds, thats the reason your buddy gave u it, most likely but he could have not knew or know about it

So your telling me if i keep it on i get a bunge femenized seeds

yea man a some bud too, it will make your change of have a tranny high again, but most female

Alright Well then what i will do try it out with one plant and cut them off on the other plant but then should i keep my light on at 12/12 or change it, because i rather have them get bigger to that i can keep the plant after harvest instead of starting all over again. I got the picture up of the grow box

allrights man remeber 12/12 is flowering and 20/4 is for vegging to grow big and strong

Alright dude thanks alot for all your help.

Okay so i use 4 cfl lights but it doesn't really keep the plants that warm because it gets pretty cold. Now i also use a chick light with a red light bulb to keep it kinda warm in my grow box. Usually i have it on at night. Now Should i just use the chick light or should i use both the chick light to warm up the the box and the 4 cfl lights?

mylar is best!

Alright thx dude
