How to properly harden tomato seeds

There are several reasons that make seed hardening a useful and practical procedure.

Secondly, hardened seeds give faster and more friendly seedlings. And, thirdly, hardening of seeds will allow in the future to increase the yield of the bush by 25-30%. But be prepared for the fact that not all seeds will survive, so take them at least a quarter more than you want to sow, and also take into account its duration - at least 3 days.

As a rule, hardening is carried out at the very end of pre-sowing treatment, and then the seeds must be immediately sown in the ground.

Tempered tempering

As a rule, this treatment lasts 4-5 days, but some gardeners advise to increase this period by 2 times.
