Before you plant
Check the growing plan
Confirm that the bag size suits your crop duration, irrigation capacity and root-zone monitoring before ordering the full crop.
Prepare before transplanting
Follow the product preparation instructions. Allow the substrate to hydrate evenly and establish your feed solution before transplanting; the growing medium does not replace a nutrition program.
Check delivery across the room
Confirm even dripper output and drainage. Review representative bags across the room before applying one irrigation schedule to every plant.

Questions growers ask
Is this 4 inch starter block format right for my crop?
Compare your crop timeline, irrigation capacity, room conditions and next-stage planting workflow. Talk through your setup with Growhaus before selecting a format for the whole crop.
Does one case contain 300 blocks?
Yes. This listing uses case SKU GH022150X with 300 blocks per case. Order quantity is the number of complete cases.
How should we prepare for a trial?
Keep the preparation, feed and irrigation records for a representative group. Review moisture distribution, drainage and crop response before expanding the trial.
Can I order for a full crop or discuss a trial?
Yes. Use Add to Quote to start a supply conversation, or book a short advisor call to discuss the format, quantities and delivery requirements. Confirm current availability before planning a crop around a delivery.
Where can my QA team get technical documents?
Contact Growhaus with the product name and any lot number. Ask for the relevant specification sheet, preparation instructions and available batch analysis.
