8 Core Light Deprivation Greenhouse Tips

Do you use a light deprivation greenhouse? Light dep greenhouses are the ideal solution for growing short-day plants and allow you to control photoperiods all year round. Light deprived greenhouses are a little different and can have some nuances that you'll want to be aware of so you don't have to learn by mistake.

1. Strain Selection

Research plant timing, harvest timing, strengths, weaknesses, and optimal plant size. Hortitech Direct Guides & How To's offer a wealth of information that can help guide you in the right direction.

2. Clones Not Seeds

Seeds are inconsistent. Cloning allows you to get predictable results from a healthy mother plant. We offer a variety of products like aeroponic cloners, rooting cubes, and cloning gels for plant propagation.

3. Prune Plants

Remove low down bud sites, branches not getting light, and browning leaves. Proper pruning and defoliation strengthens good flowering sites and boosts yields. By topping plants earlier in growth, you'll achieve a more desirable plant shape that is less tall and has more branches.

4. Remove Hermaphrodites

Stressed females can turn hermaphroditic and release pollen like males. Remove male plants and hermaphrodites ASAP or your crop could become seeded and lose value.

5. Strict Scheduling

Strictly follow the best schedule for your strain. Short-day plants require 16 to 24 hours of light for vegetative growth, then 12 hours of light and 12 hours of darkness in order to flower. Light and dark need to happen at the same time every day or plants can get confused.

6. Strict Ventilation

Ventilating your plants helps you control temperature, humidity, and CO2. Be vigilant of your plant's needs. Manual light deprivation with roll-up sides requires you to pull blackout tarps twice as often as with automated ventilation. You need to remove blackout tarps after sunset when using roll-up sides and pull them back again before sunrise or plants will not get enough fresh air and mold will be a big problem.

7. No Light Leaks

Light leaks can push plants back into vegetative growth, triggers hermaphrodites, and let pests in. Be sure to properly seal your light dep greenhouse and use light traps with greenhouse ventilation.

8. Max Automation

"We'll do it manually EZ." We're only human. Automated light deprivation provides more realistically consistent results.
