Soil Blockers vs. Speedling Transplant Trays

When deciding which seed starting equipment to purchase, always take in account the "plastic factor", or the eventual need to discard, replace, sterilize, and store plastic trays. Also, we've created the first comparative breakdown of two systems: soil blockers and Speedling transplant trays. We will use the Micro 20, 3/4" soil blocker versus the Speedling 3/4" tray.

-----------------Soil Blocker------------------------------------------ Speedling

Seeds/unit---------- 20 blocks in 10 seconds------------------------- holds 338/tray

Price ----------$29.99 one time investment--------------------------- $6.99/tray

Price/cell/block -------------$1.49 ---------------------------------------$.03

Limit------------- unlimited -----------------------------------------------338
---------------2 minutes=17 charges=338 blocks ----------More seeds?=more trays needed

Time to equal costs---10 minutes=1690 cubes=$.03/cube ---More seeds?=more trays needed

Volume of soil ----------.75 cubic inches -------------------------.25 cubic inches

Maximum time plant
is allowed in cube after
(using a tomato as the example) -----14 days ---------------------------4-7 days

Average life span ------minimum 20-40 years---------------------- less than 4 years

Cost factors -----one time investment ------------------------yearly price hikes(plastic=oil)

Time to maintain -----------------5 seconds -----------------------10 minutes
(clean, sterilize, store, etc.)

Transplant shock?----------- No ------------------------------Yes

Damage by excess water? ----No------------------------------ Yes

Sand in potting mix?---------- Yes------------------------------ No

Damaged by the sun?--------- No -------------------------------Yes

Bottom watering?------------- Yes------------------------------ No

Extra options needed? --------No -------------------------------Yes, inserts, drain trays,

This chart is helpful for those considering soil blockers but are hesitant because of past reliable performance of Speedling trays. However, you wouldn't be reading this if they lasted forever?
