Will this work?

I have almost a 8 foot tent bout seven feet tall if i line it with the shiny paper hook my 400 watt to the top.(tent will be stabalized so it doesnt colapse.) have ventalation holes, fans, ect and the plant are already a week in off unfertalized, soil, just straight dirt few inches tall.
will this grow them if i keep up constant fertalization and go 20 on four off??
also i was wondering if someone could run me through the time line on when to harevest ectt.
thanks

ok here is the best I know.
You could use a tent. You mean an actual camping tent right? They make grow tents that are ideal dementions for a grow. A camping tent will work but be very akward.

Here is the breakdown for your scheduel.
From clone 1 month (maybe 3 weeks) veg, then depending on the strain 2 monts (up to maybe 11 or 12+) to flower. Judged when done by color of THC crystals.

Harvers on a 400watter? Who knows. Its all up to your skill. A pro could maybe gett all 400 grams for 400 watts (with co2) but then again they would not be using this light I would think. Do 6-8 plants aim to veg them (lights 20 on 4 off) till they are 16 inches. Switch lights to 12 on 12 off and they will grow to 2.5-3.5 feet. Maybe get an ounce off each one depending on how well u grow

yes , it is an actual camping tent but its more like a small cabin i bought it at a garage sale, its really thick material and i think i could insulate well,
also someone explain- veg?
sorry, i new... well my city just went pretty dry due to a big bust and i am tired of relying on others to have the product,

yeah, you should totally grow. Cut out the middle men. Veg is the period that the plant is growing, it is not making buds just getting bigger, branching out and getting taller. After it gets to about half the hight you want it to finish at (ex. if you want a 2 ft plant in the end veg it till the plant is about 1 ft) flip the light to 12 on 12 off. It might actally go a little more than double in size so if this is your first time maybe go a little smaller so you don;t run out of room.

understoood thanks man, yeah about three weeks ago all our shit was coming from mexico in very large quanities on a schedule. so everyone could get hooked up easy quick and anywhere but then the DEA (Dick Eating Assholes) caught em with 768lb's and a few other large amounts of coke, and some other things. yeah me and my uncle were pissed. so i got five seed three sprouted two died from too much water i assume one is still alive , but i think i need to give away and start fresh plus my mom i pissed bout the plant haha
