Cold weather heading your way? Your Tower Garden doesn’t have to pack it in for winter. Bring it indoors, get the lights ready and keep those fresh greens and herbs coming.
A little planning makes the move much easier. Before that enormous tomato plant claims a corner of your living room, decide what you’d like to keep—and what you’d rather replace with something a little more house-friendly.
This guide walks you through bringing an outdoor Tower Garden indoors, from checking for unwanted passengers to choosing crops you'll enjoy growing all winter.

1. Decide Which Plants Are Worth Bringing Inside
You don't have to keep every plant just because it's already growing. Moving indoors is a good opportunity to harvest what's ready, retire tired plants and make room for a garden that fits your winter routine.
Keep healthy plants that fit your setup
A healthy, manageable plant may be worth keeping if you can check it thoroughly for pests and provide enough light indoors. Think about its mature size, not just whether it fits through the door today. Can you still reach the reservoir, harvest comfortably and keep the leaves within range of your grow lights?
Start fresh when the outdoor garden is past its best
If your plants are heavily infested, diseased, bolting or sprawling well beyond the tower, a fresh start is often the simpler choice. Harvest what you can, remove the old plants, clean the system and replant with crops suited to indoor growing.
Starting with fresh plants reduces the risk of carrying an outdoor pest problem into your home. It also lets you choose a more practical mix of crops rather than trying to squeeze your summer garden into a smaller space.
2. Check for Pests Before They Get an Indoor Address
Aphids don't need an invitation. Neither do whiteflies or spider mites. Check your plants before the move, even if they look healthy from a distance.
Look closely at the undersides of leaves, tender new growth, stems and growing ports. Watch for insects, eggs, fine webbing, sticky residue and damaged leaves. Separate crowded foliage so you can see what's hiding inside.
A rinse can remove many exposed pests, but it won't necessarily remove every insect or egg. Recheck over the following days and deal with any remaining problem before moving affected plants inside. Don't rely on one quick spray to clear a heavy infestation.
Once indoors, keep checking your plants and nearby houseplants. Our Tower Garden Troubleshooting Guide can help you identify problems and choose your next step.
3. Prepare the Tower and Make the Move Easier
Set up the indoor growing area first so your plants can return to their normal watering routine promptly. Move before a forecast freeze or a cold spell that could damage the crops you want to keep.
- Harvest and tidy up. Remove finished crops and dead or damaged foliage. Keep pruning sensible; you don't need to strip healthy plants just to move them.
- Unplug the pump and any other equipment. Drain the reservoir before moving the system. A full tower is heavy and awkward to handle.
- Clean as appropriate. Wipe down the exterior and inspect the pump and accessible components. If you're restarting, this is an ideal time for a thorough clean using our Cleaning & Maintenance Guide. Don't run cleaning solutions through a tower containing live plants.
- Plan the route. Check doorways, steps, ceiling height and plant supports. Get help with bulky plants or tower sections, and follow your model's instructions if disassembly is needed.
- Keep roots moist. If plants need to be temporarily removed, protect their roots and rockwool from drying out and replant promptly. Don't force an established root mass through a growing port.
- Refill and test. Once the tower is in position, refill it, restore the correct pump schedule for your model and check that water reaches the growing ports. Look for leaks before leaving it unattended.
If you're keeping established plants, don't pull them out simply to scrub every part of the tower. Save a full dismantling and deep clean for a restart.
4. Choose an Indoor Spot That Works for You and Your Plants
The corner that looks perfect with an empty tower may feel very different once it's full of kale and basil. Allow room for the plants, lights and support cage, plus enough space to refill the reservoir and reach around the tower.
- Choose a level, stable surface. Use a suitable waterproof mat or tray to help protect flooring from routine splashes, and check underneath it regularly.
- Keep power connections dry. Position cords and connections away from spills and follow the equipment's electrical instructions.
- Avoid temperature extremes. Keep the tower away from heating vents, fireplaces and cold drafts. An unheated garage may still be too cold for the crops you're growing.
- Think about everyday life. Grow lights are bright, and the pump makes some sound. Pick a space where both fit your household's routine.
Have your grow lights ready from day one
A bright-looking room isn't automatically a good growing space. Winter daylight is shorter, and a window rarely provides even, adequate light around the whole tower. Plan to use grow lights rather than hoping the plants will manage until your lights arrive.
Run Tower Garden grow lights for approximately 14–16 hours each day, followed by 8–10 hours of darkness. A timer makes that routine easy to maintain.
For Tower Garden lights, aim to keep foliage approximately 6–8 inches from the lights where practical, checking placement as plants grow. Follow the manufacturer's distance guidance if you use a different light system. Large leaves shouldn't block the light from smaller plants.

5. Choose Crops You'll Actually Want to Harvest
For a first indoor season, we'd keep most of the tower devoted to greens and herbs. They're useful in the kitchen, generally easier to manage beneath lights and don't need pollination for the leaves you harvest.
Lettuce, arugula, kale, Swiss chard, basil, parsley, cilantro and chives are all worth considering. Choose a mix that suits your room temperature and what your family eats. Keep larger crops lower on the tower and leave space for their mature leaves.
Yes, you can grow fruiting crops indoors too
If the idea of picking a tomato in January makes you smile, leave room for a compact fruiting crop. Just plan for stronger lighting needs, plant support where needed and a little attention to the flowers.
Our Best Compact Plants for Indoor Tower Gardens article covers smaller tomatoes, peppers, cucumbers and other options. Start with one or two fruiting plants rather than filling every available port with crops that will compete for space.
Check whether the flowers need your help
Tomatoes and peppers have self-fertile flowers, but indoors they may benefit from gentle tapping or vibration to help move pollen. Cucumbers depend on the variety: some need pollen transferred between male and female flowers, while parthenocarpic varieties can form fruit without pollination.
Don't assume every indoor crop needs the same treatment. Check the variety's requirements before you plant.
6. Adjust Your Care Routine for Indoor Growing
Moving indoors changes the conditions around your plants. Your reservoir may need topping up at a different rate, and the nutrient routine that worked during a hot summer may need adjusting.
- Check water levels regularly. Indoor growing doesn't mean the tower can be left unchecked. Large plants can still use plenty of water.
- Match nutrients to the plants and conditions. Fresh seedlings and established crops have different needs. Follow our Nutrient Guide rather than automatically repeating your outdoor summer dose.
- Check water quality and pH. Aim for a pH of 5.5–6.5 and use a suitable water source. The Water Guide explains what to watch for.
- Provide gentle airflow. A small fan can help air move around crowded leaves. Aim for slight leaf movement rather than a constant blast.
- Watch new growth. Check for stretching, pests and leaves growing into or away from the lights. Adjust spacing and lighting early.
If several plants start looking pale or stretched, check the light before reaching for more nutrients. And keep harvesting: regular picking helps prevent your indoor garden from becoming an overgrown jungle.
Your Before-the-Move Checklist
- Decide which plants to keep and which to replace.
- Inspect and rinse outdoor plants, then recheck for pests.
- Prepare a suitable indoor location with floor protection.
- Have grow lights and a timer ready.
- Unplug equipment and drain the reservoir before moving.
- Clean the system as appropriate for keeping plants or restarting.
- Refill, restore the correct pump schedule and check watering and leaks.
- Check plants closely during the first few weeks indoors.
Keep Growing Through Winter
You don't need to recreate your whole summer garden indoors. A manageable tower of salad greens, favorite herbs and perhaps a compact tomato can make winter growing rewarding without taking over the room.
