## Description

SPECIFICATIONS Size: 1.5”W x 1.5”D x 1.5”H Quantity: 28cubes Package: 1 Sheet ADVANTAGE Firm: hold their shape well and do not fall apart Breathable: retaining plenty of oxygen for rapid plant growth Aseptic production: Inorganic and sterile growing medium better than soil Water & nutrient retention: retains a lot of water and nutrient solution Suitable for hobby or commercial growers WARM TIPS 1.Wear gloves/glasses while handling 2.Don't try to tear the product - cut it Please Note : To Soak , simply dig plug briefly (10 sec) in a starter solution adjusted to pH 5.5 using pH down either or a lemon ,Do not squeeze the plug How to transplant rock wool block Once the you see about 0.5-1" of root growth below the plug, it is time to transplant. They can go straight into the big rockwool hole, as they do not have any wrapping on them. Your best bet is to transplant the starter plug into a 3" or 4" . WHY? It is much easier to control the moisture level in a 3"-4" than a larger block. Just wait until the block feels really light before you water. Smaller blocks like these will keep an even moisture level in the entire block. Rule of thumb: water 15 minutes before the block goes dry. If you transplant into bigger blocks: It is essential to keep the upper part of the block moist by misting or watering sparingly.

## Questions & Answers

**Q: After the seed sprouts can you put into the cup**
A: If you were careful you may be able to but you should really use this to sprout the seeds if possible.  I did put a clone in one with success but you will need to make the hole in the top of the cube a bit larger first.

**Q: do these ever expire?**
A: It won't expire, but you can try planting as soon as possible, which will be very effective. Do not place in direct sunlight.

**Q: If using for germination can you plant right into soil after sprouting or do you somehow have to remove from cube?**
A: No, plant directly into the ground and let it grow.

**Q: Will these fit my Lettuce Grow farmstand?**
A: It did not work for me,

### ⭐⭐⭐⭐⭐ Great value
*by G***M on December 26, 2025*

Order this rockwool all the time for our aeroponic tower gardens. These seem to be sturdier and do not melt away like some. Great value!

### ⭐⭐⭐⭐ spongey and malleable when wet
*by H***Y on November 11, 2023*

it’s very shapeable and stays wet for the most part. it can break apart and melt if it stays in water. it’s a sensory nightmare for sensitive skin. the whole bag is filled with dust that looks like fiberglass dust and it will get everywhere.
