Christmas cactus thrive in our hydroponic system! They're much stronger and more durable than growing in soil.
Christmas cactus have a delicate root structure that requires an even balance of water and air while adjusting to hydroponics.
That means a careful watering routine for the first couple of weeks.
Initially, an even balance of air and water at the roots will help the plant adapt. Then, gradually move to a definite wet/dry cycle similar to what the plant would experience in its natural growing environment.
Even balance of air and water at the roots
For the first 3-4 weeks:
Using the water gauge as a handle, lift plant from outer pot and take to sink. Pour KLN Rooting Solution through the pebbles at the sink (1 TBLS KLN per quart of water). Retrurn plant to outer pot with no standing water at the base.
Repeat 1-2 times a week.
Moving to a wet/dry cycle
After 3-4 weeks start using water gauge. Pour KLN Rooting Solution over pebbles until red indicators moves - then stop!
Wait until system is completley dry before rewatering. (use water gauge as a handle, lift inner pot to check for dryness).
Rewater when bottom of pot is dry.
After a couple of weeks, increase water to 1/4 on gauge. Rewater when bottom of grow pot is dry. Plant should use up all its water in 2 weeks or less.
Dump out any water left over in pot after 2 weeks and force a dry period of several days before rewatering.
Increase water to 1/2 on gauge. Healthy plants should use up all the water in 2 weeks.
Use KLN Rooting Solution for the first 3-4 weeks - then switch to a balance fertilizer for growth. (I use and recommend Dyna-Gro 7-9-5 grow formula).
