Grow Wheels Also grow wheels would require allot more mother plants to constantly produce that many clones. More mother plants, more clones = more labour, more hydro, more space, more rockwool blocks, more money. The extra cost of 1,000's and 1,000's rockwool grow blocks and disposal of them. Grow wheels have gears, motors and parts that will break down. Marijuana roots like to dry up a bit, take in oxygen between watering. Roots can't dry up in a grow wheel, because the rockwool block that it is growing in is mostly covered and sealed. Imagine 100's of plants jammed together, not good, they need air flow and space. With a grow wheel the plants grow into each other, the more they grow the less space they have. If you were to grow 8-16 big plants or 300 small plants under the exact same light, There isn't going to be much difference in quantity. A grow wheel does have more sq/ft per light, because the plants surround the light. I think FSD will have flood & drain tables on a rail system, so they can slide tables in & out of rooms, with one hand you can slide tables to different stations in the building. You can push all the sliding tables together using all of the grow space. Slide tables apart to make a lane if you need to care for them. All the watering, nutrient levels, PH, temp, humidity control will be fully automated. Everything on rails and automated illiminates most of the labour. Less employee's will be needed. To me it is the most practical and best way. It will be interesting to me to see what they do. I have allot of years growing this plant, many different methods, indoor, outdoor, greenhouses. I own 4 grow wheels, anybody want to buy them.
