what ive tried and proved that worked for me in trying to yielding the most out of a small space in the least amount of time is alot of little plants under 400w lights. My method would be putting about 40 of these small plants per 400w vegged for about a day or two in square 1.5 liter pots with a soiless mix then start flowering from there (never change pot from start to finish). The pots are placed side by side no space in between them but i would trim them to be single cola plants and make sure each cola grows straight up not leaning into the other plants space. I would also set it up as a perpetual grow space dividing flowering time between how many 400s usually by 3 or 4 harvesting every 2weeks to 2 weeks and 5 days also by alternating big and small rows of plants to improve air circulation and light penetration. My lamps are usually around 5-8 in above the tallest cola which usually isn’t more than 2 feet in height including pot height and younger plants are placed on pots one to double pot height to get the younger plants closer to the lights instead of moving the lights closer to it so all of the plants are pretty much mixed up in a orderly chaos of plants starting to flower next to ones just about to finish all pots are put in trays of 8 that perfectly fit the 8 and is thin enough to keep the pots right next to each other. Ive tried a few different strains this way and they always came out nicer looking buds then its bigger counter part. Doing it this way pending on strain would get you an average of 12-18g per plant. Ive grown a few that hit above 20g per very rare but it happend a few times. You would get some that weigh less about 8 grams was the lowest ive ever recorded but thats also rare if everything is healthy without bugs!!! (the few last batches i had got hit by stupid spider mites but they averaged around 8 grams some hit 12-14 but keep in mind this is when everything was sick with bugs and chopped early but still produced danky buds around 6 1/2 to 7 weeks. Also im all the way out on Guam so access to a hydroponic shop (for good organic pesticides or any other good types of bug killers so i was stuck with the bug with no way of getting rid of them and i tried ciggerates in water with hot pepper and all those homeade crap that didn’t do anything) or any place to get lighting equipment cause i dont want to use a credit card to purchase equipment in fear of BS coming to my door with it im using 400w HPS flood lights like the ones on top the buildings to light up the parking lot i took it apart and made me a homemade grow lamp. Its all backyard stuff i have a big c02 tank but no regulator so i dont use c02 in my rooms either and im attaining these numbers per plant. All in all it takes from start to finish mostly pending on flowering time of strain around 8 weeks (sometimes even 7 1/2 weeks) and 2 days (1-2 days for veg) to the max 9 weeks i dont take on sativas unless im gonna do a whole batch of em cause they usually gain about a foot over everything else and like i said we are going for most bud in the least amount of time. So everybody is saying 2 gallons with like 3-4 week veg time and flowering about 12 of em under a 1000w making about 2 3 maybe 4 Os per plant thats 4 at max in a 4x4 (16 sqft) space 12x4Oz= 48 Oz under a 1000w light in 3 months about max. My space is a 3.5x6 for 3 400w lamps (5 sq pots x 8 sq pots per lamp) cut that in 2/3 to try and match the 1000w with 800w in a 3.5x4 (14 sqft) space lets say all of them my way hits max (remember im lacking alot of stuff cause its a backyard setup so if i added c02, better aircooled 400w lights, and mylar instead of just flat white, my best was over 20g without the use of any of these) 80x18g= 1440g = 51.42Oz under 800w in about 2months i can harvest 2 times more in a years time by taking alot of time out of vegging and straight into flowering. Pros and cons
CONS) this way is alot of work cause u have 80-160 individual plants in individual pots so u have to make sure u dont miss any when u water i missed alot cause i was plain ol lazy and the next day they’re wilting so i know now which to water they take watering everyday especially towards the end, moving them around cause of constant growth i dropped at least one if not more a week had to move them around at least 3 times a week, getting enough clones to supply ur flowering room this came as a problem cause u have to constantly make clones so you need space for more mothers or a really big one. (PROS) THIS WAY WILL PRODUCE MORE BUD in a SMALLER SPACE in LESS TIME with LESS POWER. Just think about it a smaller plant means it needs less to survive and less light to flower cause theyre so small so it needs less to be a fully healthy plant and a fully healthy plant produces very good bud. Cutting down your time means you have more time to grow different stuff and another benfit of cutting time is the shorter it is less time that something can go wrong. I dont have any pics because we have a rule about having incriminating photos anywhere but if u dont believe try growing a few plants in a square 1.5 liter pot and see what numbers your making just 1-2 days veg and the rest flowering in the same pot also another test is take 2 clones put one in a small pot and on in a big pot and check the quality change if any. Ive tried alot of different supercropping from fiming, snapping branches, to LST with a hard flexible wire and placing each tip where i wanted it, they worked yea but even at that couldnt touch the yield i got in the same time as my little ones. You guys probably wont believe but try a few small one single cola and see how it goes thanks for reading
