Hardening of tomato seeds: the main methods and rules for conducting

How to properly harden tomato seeds

There are several reasons that make seed hardening a useful and practical procedure. Firstly, in this way it is possible to significantly improve the adaptability of plants to environmental conditions, and, most importantly, increase its cold resistance - tomato bushes obtained from such seeds can withstand a temperature drop of -5 ° C. 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.
