When growing twistys you have to be inventive..That's a big part of the fun. If it works, If it doesn't, you've learned a valuable lesson which you won't repeat....all good.........Luck dude
Definently use the double plastic bin. Total cost will be under $100. Just buy two big plastic bins (5$ each), a bath bar from Home Depot ($10), a bunch of Y-sockets (.50 each), a bunch of CFLs (less than $20), some mylar ($1 emergency blankets), a computer fan ($20).
Then use the Hempy bucket method and you'll be ready for an easy, easy grow.
