okej jimi if i have questions for what will work without any data what is better/best but it just works i will remember you.
to tell somebody to use 1kW lamp to start one seedling that will go outside in a couple of weeks....
I dont just start 1 seedling dude. I never stated that. I also mainly use clones. Not seeds. And I also never stated I always run 1 plant per 1000w HID. I said I can get 22oz from 1 plant in a 4 x 4 from an old Barneys Farm G13 X Haze mother I have. I often run 2 plants per 1000w HID in 20 gallon pots, and then I can strategically locate 5 gallon containers around the edges. Running 2 per light requires less veg time. You have to veg 1 clone 2 weeks longer to get 22oz I normally use 3x 1000w Hortilux, or 2x 1000w Hortilux, and 1x 1150w Gavita DE fixture. But it works out best for me if I use 3x 1000w Hortilux HPS bulbs.
Last harvest I used 3x 1000w Hortilux HPS, with 6 plants, all of the same strain in 20 gallon containers, and 5x 5 gallon containers on the edges of the garden. I pulled 83oz. Strain was 2010 G13 x Haze
Between me, and my buddy, we have 12 different mother plants. 1 goes back to year 2000, and is AK47 from a pack of seeds from 1997. It wont produce but 14oz per plant in a 20 gallon container. Maybe 8oz per plant if I run 2 per light. 2 per light usually gives a slightly better harvest. Another is a 2001 NL5, and it will only produce 6oz per plant,, at the most. Closer to 4-5oz in 5 gallon containers.so I use more 5 gallon containers for that strain. Its useless to run it in 20 gallon containers, unless you veg it for 3-4 months. Which 2 months is he max I veg. Usually closer to 45 days if I run 2 of the G13 x Haze per light. Ill run 5x 5 gallon containers with the NL5, and get 20oz-25oz per light with 60 days veg
I vegged all of them last time in 5 gallon containers, under 1000w, and then transplanted 6 of them into 20 gallon containers when I flowered them. They stretch 3-4x their size in 20 gallon containers, and only 1.5-2 times their size if kept in 5 gallon containers. Theyre rootbound in 20 gallon containers by chop time. You can pull the whole container full of medium out of the container in one massive root ball.
Im also running clones, not seeds.
It also wouldnt make sense to run just 1 seed under 1000w, especially if you dont know if its male or female, and I dont do feminized seeds.
But I never said I use 1000w HID. for 1 seedling. You did.
