Electricity is relativily inexpensive here , plus you can get a commercial rate. Still getting these numbers together and will share when done.
Each table was 2.4m x 1.2. I used 4L square containers with a coarse coco mix i made myself, similar to clay ball size but coco. I top feed for two weeks to get the plants etablisehd then used flood and drain which was the reason for a very coarse medium. This performed really well and produced 1gm per watt using hps 600 indoor sun buldsx3.
Back to the question, each table needs approx 100 clones.= 600 clonesfor a 16 length,x 5 = 3000 clones. Can be done, but need good mothers etc… I actually like it.
