Grodan Improved Gro-BlocksGrodan Improved Gro-Blocks are stone wool blocks for the vegetative stage, built on an optimized fiber structure and advanced wetting technology. The result is uniform water content and EC distribution through the block, rapid root development and a stable rooting environment before transplant to Gro-Slabs or Uni-Blocks.Available across the full size range from 1.5 in Mini-Blocks up to the 8 x 8 x 8 in Big Mama, in unwrapped strips by the carton or loose blocks by the pallet. Grooved bottoms suit flood tables, trays and gutter systems, and each block with a hole accepts a fully rooted Grodan A-OK or Macroplug for efficient transplanting.Available Options Mini Block 1.5 in - Strips, Carton — unwrapped strips, 2,250 per case, 12 cases per pallet (SKU GR15UC) GR4 - Small 3 in (3x3x2.6) w/ Hole - Strips, Carton — unwrapped strips, 384 per case, 12 cases per pallet (SKU GR825UC) GR6,5 - Small 4 in (4x4x2.6) w/ Hole - Strips, Carton — unwrapped strips, 216 per case, 12 cases per pallet (SKU GR6C) GR6,5 - Small 4 in (4x4x2.6) w/ Hole - Loose, Pallet — loose blocks, 2,448 per pallet (SKU GR6P) GR7,5 - Medium 4 in (4x4x3) w/ Hole - Strips, Carton — unwrapped strips, 180 per case, 12 cases per pallet (SKU GR43UC) GR7,5 - Medium 4 in (4x4x3) w/ Hole - Loose, Pallet — loose blocks, 2,160 per pallet (SKU GR43P) GR10 - Large 4 in (4x4x4) w/ Hole - Strips, Carton — unwrapped strips, 144 per case, 12 cases per pallet (SKU GR64UC) GR10 - Large 4 in (4x4x4) w/ Hole - Loose, Pallet — loose blocks, 1,584 per pallet (SKU GR64P) Jumbo (6x6x4) w/ Hole - Loose, Carton — loose blocks, 64 per case, 12 cases per pallet (SKU GRGBJC) Jumbo (6x6x4) w/ Hole - Loose, Pallet — loose blocks, 704 per pallet (SKU GRGBJP) Hugo (6x6x6) w/ Hole - Loose, Carton — loose blocks, 64 per case, 8 cases per pallet (SKU GRHC) Hugo (6x6x6) w/ Hole - Loose, Pallet — loose blocks, 512 per pallet (SKU GRHP) Uni-Block (8x8x4) No Hole - Loose, Carton — loose blocks, 36 per case, 12 cases per pallet (SKU GRULC) Big Mama (8x8x8) No Hole - Loose, Carton — loose blocks, 18 per case, 12 cases per pallet (SKU GRBMIC) Key Features Uniform water content and EC distribution Optimized fiber structure with advanced wetting technology Rapid root development and excellent control Grooved bottom aids drainage and suits a range of cultivation systems Single plug hole accepts rooted A-OK or Macroplug starters Sizes from 1.5 in Mini-Block to 8 x 8 x 8 in Big Mama Unwrapped strips by the carton or loose blocks by the pallet Ideal Applications Vegetative stage production Transplant step between propagation plugs and slabs Flood table, tray and gutter systems Automated seeding and transplanting Indoor cultivation and controlled-environment agriculture Container OrdersContainer quantities can be mixed and matched across the full Grodan and Pargro range, so one container does not have to be a single item.
