Here are some links I have found on the growing of ergot and the synthesis of LSD, please contribute other links with better instructions for non-chemists if you know of any.
1. Ergot Cultivation
2. Ergot Alkaloid Extraction (A little confusing)
3. LSD Synthesis Methods

LSD From Ergot Alkaloids
This was invented by Hofmann and is a superior method because you may proceed from the ergot alkaloids to LSD without isolating the lysergic acid. CA, 57, 12568 (1962).
Add 1.2 g of ergotamine hydrochloride to 4 ml of anhydrous hydrazine and heat 1 hour at 90°. Add 20 ml of water and evaporate in vacuo, to get d-iso-lysergic acid hydrazine. 1 g of the lysergic hydrazine is powdered well and added to 40 ml of 0.1 N (ice cold) HC1 acid. To this, cooled to 0°, is added 4 ml of 1 N Na nitrite, with good stirring. Over 2-3 min, add 40 ml of 0.1 N HC1 acid to get pH to 5. Let stand for 5 min, basify with 1 N NaHCO3, extract with 100 ml of ether, and then with 50 ml of ether. Wash the ether layer with water and dry, then evaporate in vacuo at 10°. Dissolve the resulting yellow azide in about 5 ml of diethylamine at 0° and then heat in a metal bomb at 60° for 1 hour. If a bomb is unavailable you may get by with heating for 3-4 hours at 45° in a vented flask under a nitrogen atmosphere. Also, I would flush the bomb with nitrogen before sealing and heating. Remove heat after time elapses and let stand (after bleeding off pressure for bomb method) for 2 hours and evaporate in vacuo to get 0.7 g of LSD and 0.15 g of iso-LSD. The iso-LSD will not do anything (good or bad) if consumed, so you may leave it in with the LSD. You may also separate it and convert it to LSD as in the formulas ahove.
