Heating isn’t just about extending your season. It’s a powerful lever to unlock the full potential of the sunniest months of the year. By starting to control your heat early, you benefit from the months with the most sunlight.
May can give you over 1.4 lb/sq.ft, compared to barely 0.6 lb/sq.ft in October.
Heating isn’t a cost. It’s a yield booster. This is how you reach up to 9 lbs/ft².
Heating a tunnel is not only for the plant survival when frosts occur. It is necessary, all season long, to maintain an optimal temperature. Keeping temperatures a bit too low makes your growth much slower.
In the first months, you should be able to grow one new cluster per week. If you don’t heat enough because "the plant is not dying" , you slow the cluster generation process. If you don’t maximize the number of clusters in the spring, you decrease the yield potential of the whole season!
