My plan

Hello all im brand new first post in your community. i have a plan i just wanna run by people and see if i am on the right track. I plan on using a 25 (5 x5x6 foot high) sq foot self made grow chamber with 15 feminized advanced early widow seeds under 600 watt. im gona veg them for about 4 to 6 weeks depending on how they grow if its gona be 4 or 6 weeks. the flower them. im tring to get an oz a plant hopefully. i have both hps and mh lights 600 watts each im going to switch out during veg. and flower stages. so thats the basics. does anybody see room for improvement??? is that to many plants for area? thats really all im worried about. i have some past exp. with growing things not bud but i know how it all works so any comments to help would be nice
thanks

You could fit them all in there but it will be a tight fit. You have so many possible options. You could grow half as many and get the same yield using lst. Then you could go to rounds with that amt of seeds. Obviously you can just clone your veg plants right before flowering or keep 1 mother so u don't need seeds for round 2 but it will take up more space. Doesn't sound like your gonna run perpetual with only 1 room.

Something many ppl underestimate before they start growing is the amt of heat your light is gonna put off, and how much it can cost keeping your temps down and setting up ventilation.

Make sure you think about:

Soil, organic, hydro?
Mass air exchange or co2 enrichment?
Grow methods such as lst, topping, screen of green?

So many possibilities and techniques to try and perfect. Just don't underestimate the expenses is my best advice. Keeping your environment in check is #1.

Oo I misread, didn't realise you said early widow, thought u said white widow. Well if that's an autoflowering strain (which it sounds like, but may just be a fast flowering indica) then you won't really have a choice on when you flower and cloning, although possible, is more of a photoperiod thing.

So if its autoflowering it probably won't get that big and won't yield as much as a plant that you can decide when to flower it. Probably wanna let it grow untopped or untrained with autoflowers too.

sorry im going to be putting them in soil prob. 3 gallon potts after a few transplants to get to 3 gallons. Im not really gona use any special way but let them grow thats all. i was thinking of doing only 10 or 12 plants in that area. so im basically gona plant and let them grow and of course have them on water scedules. and just let them grow. i am gona take clones from some but thats future plans. Right now i kinda just looking to know im on the right track as far as light and amount of plants for the area and wattage. as far as heat from light. right now where i live its 45 degrees room stays about 66 now but im gona have them in a chamber with in the room so for this grow as far as venting the heat from light i think as long as i cut the heat to that room crack the window and and vent light heat to recycle back in room to heat room and vent direct heat in chamber. ill have to play with the set up to see whats gona work for the next 4 mothns but ill get it. what do u think? wattage and space and set up sound ok? Im hoping to pull an oz a plant if i go with 16 plants of i go 10 plants i want the same amount. thats my goal right now. oz a plant or just above it with 10 plants only. Sound plausable for sucess at this point? i know to predect sucess is hard cuz there r so many more factor once its started but at this point i think i got a workable plan.

didnt say its an autoflower plant i just rechecked there from attuide

Cool, its probably just a fast flowering indica then which is cool. I'm not rly familiar with the strain but the good thing about it being photoperiod is you could keep them in veg as long as you want so you can clone it easily and you will be able to let it get as big as you want before flowering so 1 oz a plant should totally be possible as long as environmental conditions are good and nothing stunts them.

That is a great wattage for that size area. Its a little more than you need which is a good thing. Because then you will get nice hard buds instead of fluffies. I wouldn't go with smaller light. However when I said don't underestimate the heat I mean it. That 600 watter can easily boost your temps 20 degrees or more in that size area if its not properly ventilated. I would definately go with an air cooled hood and a fan to vent outside the grow room. if you don't need it in the winter you will need it in the summer. Your gonna want one. That's like the best advice and most important thing you will need.

Also realise plants constantly need fresh co2 so you will either need to constantly exchange the air in the room with ventilation or use co2 enrichment. I run a sealed room so use co2. You will want a fan capable of exchanging all the air in your room in 2 or 3 mins. That shouldn't be hard at all the for a room your size.

Sounds like ur on the right track. I just can't stress enough about your ventilation. You will need it I promise. Don't underestimate the heat from your light. Alsi ventilation is the best way to keep ur humidity in check.

That's a pretty good space for that many plants (IMHO) but your 600w hps may not be enough. IF you could run both your HPS and MH and keep your temps down then you're talking.

I'm running a 4' x 4' grow tent and can run up to 12 girls in 3 gallon smart pots, my only issue right now is I need to switch from a cooltube to a larger hood.

Good luck, happy growing

If he uses an appropriate hood a 600 watter is perfect for 5x5 area and to still get nice dense buds.

I won't disagree with that but ever since I upgraded from a 2' x 4' running 600w to my 4' x 4' I've been researching supplemental lighting. To me, it just seems like a little more would not hurt his situation one bit.

Anywhere you look at dimesions per lights it will say 400w = 4x4 , 600w = 5x5. 1000w = 6x6. That's what the light manufacturers will tell you, growing books, I've never seen anything different. Obviously more light CAN be better but when considering the size of his room, and the next step up being 1000 watts that will be way too hot. You can always argue more is better, but 600 watts in a 5x5 room will in no way whatsoever be lacking. its the optimal, suggested, and standard wattage for that size room.
