The Soviet Union had major food problems in the 1920's, what with the civil war and an attempt at forced requisitions. Their solution was the NEP, which used grain taxes instead of total requisition, and did state capitalism for the economy.
Did Lenin or anyone else investigate greenhouses around this time? It seems enclosed greenhouses would allow food production anywhere in Russia, rather than relying on the grain belts and transporting huge distances. (In fact I remember reading about Khrushchev's agro-town concept in the late 1950's, though I don't know if those were proposed greenhouses.) It would require much more work to build, but if they successfully electrified the country in the 20's, I would guess they could build them.
Instead, Stalin abolished the NEP in 1928 (and also re-instituted internal passports to tie the peasants to the land), and proceeded with total collectivization to support total industrialization very soon.
